How to Kill Cancer Naturally- A Guide

As you've seen in previous posts about what causes cancer, The Basic's of Cancer- in Layman's Terms and One in Three Will Get Cancer, the way we optimize our health is by killing active cancer cells and reestablishing a balance within our body.  This is not solely about cancer, as the beginning of most health issues begins with inflammation.  When you are diagnosed with cancer, you can either choose traditional treatment of surgery, chemotherapy and radiation, or you can treat it naturally.  But if you choose the former, traditional treatment, you will need to work much harder to create proper balance after treatment.....that is, if there ever is an "after treatment".  Many will remain in traditional treatment until their demise.  

With what I know now, I would have never agreed to conventional treatment before trying the natural approach.  The problem was, I didn't know about the natural options prior to having cancer treatment. I didn't even know anything about cancer!  There are so many sources for information on the internet, and so many conflicting opinions, it's nearly impossible to filter through, especially when you are scared beyond belief and holding your new cancer diagnosis.


As I researched cancer, I started to develop a clear understanding and strategy for getting healthy.  Once I finished chemotherapy and surgery, I chose to turn down radiation and get my immune system up and running as fast as possible.   A strong immune system is an important way to prevent cancer and recurrence.  I wish I had known what to do from the very beginning.  I could have avoided all of the torture of conventional medical treatment.  Regardless, here is what I know now.




In my research, I found the main things required to treat and prevent cancer within our body are... 


Create Healthy Bloodflow- Thinner blood, unclogged arteries, healthy blood pressure and increased circulation all work to prevent damaged and sedentary cells from mutating to form cancer cells.

Reduce Oxidative Stress-  Toxins and bacteria enter our bodies and create free radicals (damaged cells).  These damaged cells can mutate to form cancer cells, dividing and multiplying to form tumors.  Anti-oxidants play an important role in scavenging free radicals and killing them before they mutate, relieving us from oxidative stress, inflammation and premature aging.


Boost the Immune System-  The immune system is our biggest ally in preventing cancer.  Our white blood cells devour toxins, bacteria, and viruses.  Sugar can be detrimental to our white blood cells, so one of the ways we can boost the immune system is to prevent excess sugar (glucose) from getting to the white blood cells either by reduced consumption or blockage of glucose.


Reduce Acidity-  Cancer likes an acidic environment.  Not only does it thrive in acid, it creates it as a byproduct of cancer growth.  A diet full of soft drinks, red meat, and processed foods all greatly increase acidity in the body.  But one of the biggest acid producers in our body is stress.  By living with a great deal of stress, the body is constantly producing and retaining lactic acid in muscles....cancer's favorite environment.





Now that we know WHAT to do, 
how do we go about doing it?

This is where we "CONNECT THE DOTS"


There are four categories of what I feel are the most important components to combat not just cancer, but diabetes, heart disease, arthritis and many other systemic ailments.  The first category is called GOLD, the strong active cancer killers.  These are the strongest, most important compounds that have proven to cause cell death in many different types of cancer.  And even more importantly, these have little to no negative side effects.  Because these in particular are so important, there are links to each ingredient to another blog post with information about them and references from clinical studies done on each one.




Category One 
GOLD
Strong Active Cancer Killers



Black Cumin Seed- Nigella Sativa comes from a flowering plant found in Asia.  It has been used in Chinese medicine for centuries, as far back as the 5th century BC, and was even found in the tomb of one of the Pharaohs of Egypt.  It is a strong anti-oxidant, produces apoptosis (cell death) in cancer cells, increases circulation, and is used in treatment for cancer, diabetes, heart disease, epilepsy, allergies, colitis, and numerous other ailments.   It boosts the immune system and bone marrow.  They are also a good source of Omega-3 Fatty Acids.  The health benefits of Black Seed and Black Seed Oil are extraordinary.  Works in synergy with Honey.





Indian Long Pepper Fruit- Piper Longum has also been used for centuries, and its use dates back to the 5th century BC.  This hardened unripe pepper has proven to be a strong anti-oxidant and anti-bacterial agent.  It has shown activity against parasitic infections, protects against the effects of radiation, and induces apoptosis in many different cancer cells.  It has been proven to be effective against prostate, breast, ovarian, and colon cancers, as well as melanoma, lymphoma, leukemia and glioma tumors.  There's so much punch packed in this small fruit.  Works in synergy with Curcumin (listed below).



Mangosteen- Garcinia Mangostana is a strong anti-oxidant.  Many studies have shown this fruit's anti-cancer effect on breast, prostate, bladder, pacreatic, colon, melanoma, and colorectal cancers.  There are more than 50 xanthones found in the pericarp of this fruit, with many found to be beneficial in fighting cancer, reducing tumor growth and preventing metastasis. Mangosteen also works as an anti-inflammatory, and its effect on insulin production has been found to be therapeutic to those with diabetes or obesity.  Controlling glucose levels plays a key role in weight management and cancer prevention.  Works in synergy with Curcumin.




Dandelion Root  Yes, I mean the root of that inconsequential little weed growing in your yard.  This little plant is packed full of nutrients and cancer fighting properties. Numerous studies have now shown the great benefit of these little plants.  They have proven to be a strong anti-oxidant, inducing apoptosis in cancer cells in pancreatic cancer, leukemia, breast cancer, prostate cancer and even drug-resistant melanoma.  The root of the Dandelion contains high concentrations of Vitamin A as well as other important vitamins, and acts as a diuretic, cleansing the kidneys and liver.  Other evidence has also shown that this little plant can also positively affect insulin secretion.


Curcumin comes from the Turmeric Root, a yellowish root from the ginger family.  It is a strong anti-oxidant which protects the body from oxidative stress and inflammation.  It has been proven to be effective against cancer, Crohn's, Ulcerative Colitis, Alzheimer's, Diabetes, and even Cystic Fibrosis.  It has great wound healing and pain relieving benefits, as well as the ability to increase circulation and lower cholesterol. Works with Long Pepper and Mangosteen.



Bitter Melon- Momordica Charantia is a bitter vegetable native to Asia and is used in Asian cooking.  It has been used in Indian medicine to treat diabetes by inhibiting glucose transport throughout the body.  It has the ability to cause apoptosis, or cell death, in cancer cells.  Bitter Melon has proven to be effective against breast, lung, prostate, bladder, colon, liver, lymphoma, neuroblastoma, leukemia and other cancers.   In regard to breast cancer, one study in particular showed very promising results.  When breast cancer cells were exposed to Bitter Melon's extract, 80% of the cancer cells died within 48 hours, and none of the normal cells were affected.   You can see more information about this study here. 


Side note:  There are other compounds found in nature to be strong cancer cures not listed here.  One of the most powerful is the Cannabis/Marijuana plant.  In fact, the US Government Department of Health and Human Services holds the patent on the extracted compounds of Cannabis that prove effective against cancer.  However, due to the plant's legality in many states, this has been excluded from the list.  


Other strong, natural cancer cures include Essiac Tea, Black Salve, Soursop, Astragalus, DIM and Vitamin B17, also known as Laetrile.  Although these compounds are proven to be effective against cancer, they also may come with serious side effects or contraindications for many people.  I intentionally left those out due to their potential complications.  





Category Two  
SILVER
Strong Anti-Oxidant Plus+


This category of natural compounds includes major players in preventing oxidative stress.  Like the ones above, they have cancer fighting ability to induce cancer cell death, but their role is more importantly to help alleviate inflammation caused by oxidative stress and improve circulation, cardiac function and glucose management.  These are also extremely important in building the body's immune system. 


Resveratrol comes mainly from the skin of red grapes.  It improves cardiac function and physical capacity.  It helps reduce inflammation, prevents the oxidation of LDL cholesterol and makes it more difficult for platelets to stick together and form the clots that can lead to a heart attack. Resveratrol is thought to limit metastasis of cancer cells and triggers the process of cancer cell death in Bladder, Colorectal, Gastric, Cervical, Liver, Ovarian, Colon, Breast and Leukemia.  It also helps prevent insulin resistance, a condition in which the body becomes less sensitive to the effects of the blood sugar-lowering hormone, insulin.


Taurine is a sulfur-containing amino acid found in animal tissue.  This strong anti-oxidant is known for it's ability to improve cardiac function by a number of pathways, including lowering blood pressure and reducing oxidative stress.  It calms the nervous system resulting in less reaction to stress, and it supports insulin health, helping to prevent diabetes.  Low Taurine levels are newly becoming a marker for many types of cancer.  This essential amino-acid is also a strong anti-inflammatory. 




Ashwagandha / Indian Ginseng has been known for centuries for its rejuvenating and healing properties.  It has adaptogenic properties which allow the body to deal with emotional and oxidative stress.  It is full of amino acids and vitamins.  This herb is often used for energy and vitality, memory and concentration.  Ashwagandha has also proven to have potential in selectively killing tumor cells by causing apoptosis.     





Green Tea is loaded with strong anti-oxidants that improve brain function, lower the risk of cancer and enhance fat loss. It protects cells from damage due to toxins and bacteria. It is an anti-oxidant, anti-microbial, anti-viral, anti-tumor and anti-bacterial agent.  It may also reduce risk of stroke.  Other studies look at it's ability to inhibit metastasis specifically in breast cancer cells.   







Rhodiola Rosea is also known as the golden root or arctic root.  It is a strong anti-oxidant known for it's ability to prevent fatigue, relieve depression, protect the kidneys from damage and induce apoptosis in cancer cells.  It's also a free radical scavenger and improves heart function. 






Gotu Kola / Centella Asiatica is a swamp plant that grows in Madagascar and Indonesia.  It has been used for centuries for wound healing, mental fatigue and concentration, anxiety, dementia, skin conditions, and respiratory infections.  It protects the cells against oxidative stress, and has been shown in studies to reduce liver tumors.  Gota Kola may also protect the skin against Gamma radiation. 





Category Three  
BRONZE
Probiotics and Enzymes

Category three, Bronze, provides fundamental bacteria and live enzymes that establish a functioning chemical balance within the body.  



Probiotics are comprised of the working bacteria mainly contained in the gastrointestinal tract where 70 to 80% of our immune system cells are found.  Probiotics help prevent infection, inflammation, and may even bind to carcinogens in the intestinal tract, promoting their excretion.  They are essential for optimizing a properly functioning immune system.




Enzymes are proteins that speed up the chemical processes in the body, mainly digestion.  There are many types of enzymes all throughout the body, however the role of digestive enzymes is to break down the food we eat for our body to properly utilize the nutrients.  Raw, plant based foods contain the highest levels of enzymes, but most of us eat cooked or processed foods that no longer contain these beneficial proteins, leaving us deficient.  Stress can also lead to low enzyme levels in the body, compromising our immune system further.  Low enzyme levels are also linked to Liver, Pancreatic and Ovarian Cancer. 



The most important enzymes are as follows:


Quercetin is a plant pigment and flavinoid found in fruits and vegetables, mainly apples, onions, grapes, and berries.  It is a strong anti-oxidant, anti-inflammatory, anti-histamine, and may protect against heart disease and cancer.  It may also suppress insulin receptors, impairing cancer cells' ability to multiply.  Quercetin has also been proven effective against cancer in Breast, Ovarian, Bladder, Prostate, Oral, Pancreatic, Cervical, Head and Neck, Lung, Liver, Renal, and Leukemia.   



Bromelain is a protein extract found mainly in the stems and juice of the pineapple.  It has been used for centuries to reduce inflammation and aid in the wound healing process. Used in conjunction with Quercetin, it aids in digesting and utilizing a greater amount of Quercetin.  Bromelain has been shown to be effective against the following cancers:  Mesothelioma, Breast, Gastrointestinal, Colon, Glioma, and Skin Cancer.  



CoQ10 is an anti-oxidant that is found in every cell.  It is found naturally in the body and in many food sources, and helps convert food into energy.  It is at the very basic level of cell function.  A deficiency in this can cause chronic physical and mental fatigue, high blood pressure, poor blood sugar regulation, stomach ulcers, heart failure, and poor response to depression medication, as well as a number of other ailments.  In regard to cancer, CoQ10 has proven to combat oxidative stress and relieve chemotherapy related fatigue.  



The Big Three- Amylase, Protease and Lipase are digestive enzymes that break down starch, protein and fat within the digestive tract.  As we age, the number of enzymes our pancreas excretes reduces.  If we are deficient in these digestive enzymes, our cells do not get the proper nutrients from food.  A deficiency is also caused by eating cooked, processed or irradiated food, killing the live enzymes.  This can create inflammation within the body as well as compromise the immune system.  Cancer patients have notably low levels of enzymes, and new studies are emerging with the use of enzymes as a therapy for cancer.   


  Category Four  
THE BASICS
Vitamins, Nutrients and Minerals


This final category is about the basic compounds we need in our body to function optimally, reduce oxidative stress, build muscle, reduce acidity, promote a healthy immune system, reduce inflammation and prevent negative systemic responses and illnesses.  Most of these can be found in a healthy, well rounded diet, but may need to be supplemented.  

1.   Daily Multivitamin with Selenium
2.   Vitamin D- Supports healthy immune system
3.   Iodine- Deficiency may cause Thyroid or Autoimmune problems
4.   Sodium Bicarbonate (Baking Soda)- reduces acidity
5.   MSM (Methylsulfonylmethane) sulfur- used for joint health, circulation, wound healing 
6.   ALA (Alpha Lipoic Acid)- Helps turn glucose into energy, builds Gluathione levels, and is a strong anti-oxidant
7.   Melatonin- Free radical scavenger and sleep aide
8.   Cayenne- Digestive aide and promotes healthy circulation
9.   Ginger- Digestive aide and nausea preventative
10. Cilantro- Detoxifies the body of heavy metals
11. Garlic- Improve immune function, reduce blood pressure, improve cholesterol, strong anti-oxidant

One in Three Will Get Cancer

Did you know that one in three people will get cancer over the course of their lifetime?  And that rate is rising every year.  Take a good look at the people around you and ask yourself, are you that one?

Did you know that with standard cancer treatment of chemotherapy, the five year survival rates are staggeringly low?   With the five most common adult cancers combined, the five year survival rate is 1.6%.  That's it.   Breast cancer isn't much better at 3.5%.   That is unbelievable to me.   Reference

And we are all, myself included last year, lead to believe that this is the only way we will survive.  We get treated with surgery, chemotherapy and radiation, because that is the only option we are given.  It's this treatment or death.

Going through chemotherapy and surgery was literally torture, both mentally and physically.  To be stripped down to an unidentifiable science experiment is degrading, mortifying and downright scary.  I lost my dignity.  I lost parts of my body that identify me.  I lost my physical strength.  I lost my income.  And worst of all, I lost my children.  And to find out now that it didn't have to be that way is infuriating.

Cancer comes from an imbalance in our body.  Toxins that damage cells outnumber what the immune system can handle.  It's simple.  Build the immune system, restore the balance.

Why is the survival rate for conventional treatment so low?  Because chemotherapy destroys the good cells with the bad.  There is no differentiation of normal vs cancer cells.  It kills the very thing we need to protect ourselves.  This is a fact.  And this is the reason that many people have recurrence of cancer within a short time of finishing treatment.

Just because I had complete response to treatment does not mean it will not return.  My body was obviously out of balance to create the cancer in the first place.  And now, after treatment, it's even further weakened.  That's why it's so important to bring in strong natural ways to build the immune system quickly.  Whether you choose to do chemotherapy or not, it's crucial to reverse the imbalance.

Many people in later stages of cancer are not given a break from treatment.  They remain on chemotherapy until their end, with doctors saying they are prolonging their life and giving them a better quality of life.  In my opinion, staying in a perpetual state of "miserable, but just getting by" is exactly where the money is for the pharmaceutical companies, a whole nation of people dependent on them to keep them sick.  Many will even give up and let the cancer take over.  It doesn't have to be that way.

There is another option, a better option.  There are natural cures all around us.  Not treatments, cures.  Getting your body in proper balance will cure and prevent not just cancer, but many systemic ailments as well.  We've become so dependent upon the next pill, that we've forgotten that we have everything we need right in nature.  And it doesn't cost millions of dollars.

The Basics of Cancer- In Layman's Terms

Let me start by saying this.... When I had cancer, I started with traditional cancer treatment.  I did seven rounds of chemotherapy and five surgeries.  By the time I learned about the natural options, I was in the middle of chemotherapy and was advised not to take anything else.  Traditional medicine killed the cancer and I am thankful for that.  However, the effects of chemotherapy and surgery do not stop when they are done, and I personally wish I could have avoided that by at least trying the natural approach first. Once I knew about the natural options, I shifted my treatment, turning down radiation, and opted for a more natural approach.

The following post is not to intended to replace medical treatment.  It is merely to give you more information to make your own choices regarding your health care.  The ultimate goal is to prevent cancer and recurrence altogether and avoid the torture I went through.
_________________________________________________


When I was diagnosed in September 2013 with very aggressive breast cancer, the first thing I did was start reading.  I needed to understand what was in my body, why it happened, what did treatment entail and what my prognosis was.  I spent hours, days, and weeks researching.

You would be surprised at the sheer volume of information and misinformation that is found on the internet.  And for the average person to wade through this, it's more than discouraging to say the least.  But I stuck with it.  I kept reading, and eventually, I worked my way through to a greater understanding of this terrible disease.  One thing I know for certain is, you can't believe everything you read on the internet, even by the government and pharmaceutical companies.  I think back to when I first started reading about cancer, and I was beyond terrified about what I was finding online.

Now, after over 7,000 hours of reading, researching, and even experimenting with my own body chemistry, this is what I have found to be true.

First, cancer is preventable.

If we control our sugar levels, build our immune system, and rid our body of the things that cause oxidative stress, then we can prevent cancer from forming.  How, you ask?  I talk about how cancer begins in a previous post called How Does Cancer Begin?


Okay, now that we know the basics, what can we really do to help ourselves?

The truth is, sometimes we just don't know what causes toxic overload or oxidative stress in our bodies.  When we combine GMO food, processed food, beauty products, cleaning products, deodorant, soaps, environmental pollutants, medications, cigarettes, old dental work, and basically anything we come in contact with on a daily basis, we are making ourselves vulnerable.   Every time we breathe, we are exposing ourselves to toxins, moreso now than ever before in history.  Scary, huh?

So the goal should be to get these toxins out of our body before they start causing problems.  Who's responsible for that?  The immune system.   The job of the immune system is to send out white blood cells to find all those damaged cells and devour them.  But sometimes our immune system can't keep up with the demand or they're distracted.  Sometimes there are too many toxins in our bodies and the immune system becomes stressed.

But the biggest culprit of a weakened immune system is sugar.  I know people say, "Sugar feeds cancer", but this is not the function I'm talking about.  When we eat simple carbohydrates, processed foods, and sugary foods, not only do we have an overload of glucose in our blood stream to feed damaged cells, but our white blood cells get confused and absorb that sugar too.

When the white blood cells have too much sugar, it changes their ability to absorb damaged cells.  Their process is hindered for up to five hours at a time.  This is the moment when the damaged cells starting changing and multiplying.  Unfortunately, because of the addictive nature of sugar, we may eat it far more often than every five hours.  So our white blood cells never really get a chance to do their most important work.

Did you know that we all have cancer cells in our body already?  Are we feeding them?  Are we encouraging them to grow by adding more toxins and withholding our immunity to them?

Great, so what you're saying is, I can't have any fun or eat any delicious food like steak and cake....

Well, in theory, we would all be using natural products, eating organic plant-based foods, and we would be running through fields of green grass and standing on mountain tops breathing fresh air.  How realistic is that on a daily basis?  We have become dependent upon convenience for food and rarely get our proper time in nature.  We have responsibilities, you know!

That said, we can try to create a better balance in our bodies by trying to include more plant-based foods and less sugar.  And we can reduce the toxins in our bodies by stopping smoking, shifting away from more chemical based products, and getting out in the sunshine and fresh air.  But there are some other natural ways we can help our bodies achieve a better balance.

There are plants found in nature that will clear our body of toxins and damaged cells.  There are natural immune boosters.  And most importantly, there are natural ways to prevent our body from going into sugar overload, even when we DO eat those delicious cookies.  These plants can even reverse damage that has happened within your body, including premature aging, diabetes and cancer.  These things in nature have been around for centuries and have little to no side effects.

Why don't doctors prescribe natural cures?

Doctors are governed by protocol.  They must do what the government has deemed appropriate care for patients whether it's good for us or not.  Sadly, just like the food industry giants, there is an overlap and inbred relationship between the government policy makers and pharmaceutical companies.  If they cannot make money on the medication, it is not prescribed.  And cancer is expensive!  My year of cancer was nearly $50k a month for chemo, and hundreds of thousands of dollars for surgeries. In total, my breast cancer was close to $400,000, and that came out of the taxpayers' money because I was on Medicaid.
This was me getting what they call the "Red Devil"

Why is this a big deal?  Because statistics show that with chemotherapy and radiation, the odds are not much better than going it alone.  It extends life in some cases, but many are left with debilitating problems and subsequent cancers from treatment.  I remember signing a statement before getting my first chemotherapy that said I understood I could get bladder cancer from this particular drug.  Then the nurse suited up and warned that the drug will eat through skin if it touched it...as she was pumping it into my veins.  It's terrifying.

Why don't pharmaceutical companies promote natural treatments if they work so well?

Great question!  In my research, I have found that there have been many natural plants, herbs, fruits and vegetables that have tested as well as or even better than chemotherapy in clinical studies. And the best part is that they have little to no side effects.  When they find something that works and kills cancer, scientists get to work to determine what compound in this plant is responsible for the great results.  Then they try to extract that one compound and patent it.  The patent is where the money is.

But many of the plants found in nature that have cancer killing properties need to be in whole form.  ALL of the compounds working symbiotically is what kills the cancer cells.  When that happens, it's proof that it was created perfectly already.  However, that cannot be patented.  In cases like this, the pharmaceutical companies drop the study and move onto another that can potentially make money.

At the same time, the plants that they have proven to kill cancer in clinical studies are now suppressed.  We continue to trust that current chemotherapy and radiation treatments are the only way we will have our lives extended.  When you look at internet sites run by the large cancer societies, treatment centers or research facilities, they try to scare you away from any of these natural substances.  They say you will die if you take them.  Or they say they aren't effective despite what the clinical studies have proven.

So what are we supposed to believe?

Everyone has to do what's right for them.  And trusting your doctor to do the best thing for you is a big deal.  But at some point, you must question the safety of these toxic drugs.  At some point, you must look at what you are putting into your body and question, "Why this one? And will it kill cancer or just prolong my life?"  Start looking at ways you can actually get your health back, not just survive a couple more years.   Do I wish I had done this differently now that I know all of this?  Absolutely!

Had I known that I didn't have to torture my body and put my future at risk, I would have gone a natural route.  There ARE natural plants, herbs, fruits and vegetables that will cure cancer.  There ARE ways to get the body's chemical balance back in line.  There ARE ways to get healthy by not spending half a million dollars.

Don't be swayed by all the scare tactics by pharmaceutical company propaganda.  These cancer killers do not have to be toxic to our body.  If I had given the natural treatments a month of experimentation before signing my life over to seven rounds of toxic chemotherapy and five surgeries, I feel I would be in a MUCH better place right now.  I just didn't know what to take and why.  But that's what I know now!  And you all get to benefit from my hard work.

Okay, you keep talking about all these amazing things that work, but what exactly are they?

After thousands of hours of research, I've put together a list of what I feel are the most important cancer killers.  Some things rid the body of free radicals, damaged cells, toxins and block oxidative stress within the cells.  Some things prevent spikes in blood sugar, thus preventing sugar from overfeeding the cancer cells and white blood cells.  And there are some things that promote immune system health.  ALL of them are from sources found in nature!
