What Causes Cancer

What causes cancer? The answer to this question is not a simple one. Cancer has several causes because there are a multitude of factors that negatively affect the environment of our cells and their DNA.  

Healthy cells can turn cancerous when they are under assault by toxins, microbes, and radiation, and unhealthy environment caused by inflammation and lack of proper nutrition. It's normal to have a number of rogue cells in our bodies at any given time. It's also normal for cancer and the immune system to interact. Those cells are usually targeted and killed. When the immune system becomes compromised, they escape detection, multiply, create tumors, and metastasize. This can happen at any age, but the older we get, the more our odds increase.

More than 10 million people worldwide will hear the scary word “cancer” this year from their doctors. It is predicted that one out of every two men, and one out of every three women will get this diagnosis in their lifetimes. 

Why Do Cells Become Cancerous?

The DNA inside of the genes hold instructions for the cells. As long as the instructions are accurate, cells reproduce, function and die as they are meant to.

Nobel Prize winner, Dr. Otto Warburg,  proved way back in 1931 that when cells are denied 60% of its oxygen requirements, they could turn cancerous. This is because they start meeting their energy requirements through sugar fermentation instead of oxygen. 

When DNA is damaged, cells do not function properly and they change. They multiply exponentially because the regulator that tells them to stop reproducing is turned off. Once cells turn cancerous, they stop communicating with other cells and grow their own blood supply.

Not all cancer cells are the same. Some act as stem cells that reproduce themselves and sustain the cancer. These cells produce a sticky protein coat that helps them clump together as a tumor and stick to new sites. It helps them metastasize and become invisible to the immune system. They also produce the enzyme, survivin, that keeps them from dying like regular cells.

Risk factors for DNA damage and cancer

There are multiple reasons why DNA in the cells get damaged and produce cancerous changes. Genetic defects are responsible for 5-10% of cancers. Otherwise, environmental and lifestyle factors are what causes cancer in the remaining 90-95% of people. Following the general guidelines for living a healthy life goes a long way in regulating hormones that could raise the risk of certain cancers. 

It is estimated that 25-30% of cancers are due to tobacco use (90% of lung cancers). Poor diet is blamed for 30-35% of cancers and 15-20% are caused by infections. 

What causes cancerous DNA? Environmental and lifestyle risk factors include:

  • toxicity 
  • dehydration
  • poor nutrition 
  • processed meat
  • heavy metals
  • hormonal changes 
  • specific microbes 
  • physical inactivity
  • stress
  • radiation
  • smoking
  • drugs and alcohol
  • obesity
  • chemotherapy

Damage from one or more of the above factors can cause cancer and the chronic inflammation that fuels it.

Poor Diet and Cancer

With poor diet being blamed for one-third of all cancers, we can see how important a healthful diet is for cell and immune system health. Cells can not function optimally without the nutrients needed for fuel. They cannot function properly when fed a diet high in processed food, GMOs, sugar and trans-fatty oils. 

A diet high in sugar suppresses the immune system and feeds cancer cells. Sugar, processed food, and red meat are very acidic. Cancer thrives on acid and produces acid. It loves sugar so much that doctors use radiated sugar in PET scans to find cancer in your body.  Almost 50% of cancer patients die from malnutrition because cancer cells are more efficient at absorbing sugar than normal cells.

Even a few teaspoons of sugar can suppress the immune system for hours. If you eat sugar or a lot of simple carbohydrates, your immune system is probably suppressed much of the time. This gives cancerous cells the edge they need to take hold and thrive.

GMO “food” is another main dietary concern. Experiments on rats showed that up to 80% of females had mammary tumors and 50% of the males had tumors from GMO corn which also caused premature death. The genetic fragments from GMOs can change your gene expression and your physiology. Much of our corn, wheat and other food staples are now being genetically altered. 

Processed meat increases your risk of colorectal cancer by 18% when you eat only 50 grams per day (less than 2 ounces). Pancreatic, prostate, stomach and other cancers are also positively linked to processed meat and consumption of conventionally raised red meat. 

Obesity is a risk factor for cancer. Fat cells are not carcinogenic, but obesity promotes inflammation. Inflammation is produced when your immune system releases powerful chemicals to make an affected area less hospitable to invaders. Normal cells find this toxic environment inhospitable, so they try to protect themselves by producing growth factors. Growth factors are estrogenic.  Excess fat cells are also estrogenic. Estrogen causes cells to reproduce faster. 

The Toxin-Cancer Connection

Most people are regularly exposed to a wide variety of toxins through chemicals in the air, water, even in their homes, food, medicines, and personal care products. Acidic metabolic waste products must also be detoxified. All of these toxins put a burden on your organs of elimination. They contribute to acidity in the body and oxygen deprivation, along with excess stress, being sedentary and scrimping on sleep. 

There is a clear connection between toxins and cancer.

Pesticides, herbicides, and heavy metals including lead and mercury are contaminating our food, water, and air supply. Some of these toxins can stay in water and soil for hundreds of years. In the U.S. alone, two billion pounds of chemicals are dumped on food crops every year. This doesn’t count the billions of pounds used for other reasons. Coal plants in China spew out mercury and other heavy metals which are carried by winds.

Toxins and metals negatively affect the body in many ways. They mimic hormones, damage the gut lining, and stress the detoxification system. Roundup, which is used as an herbicide and is allowed to be sprayed on 160 produce crops, kills good bacteria, not bad bacteria, and is implicated in leaky gut, inflammation and  colon cancer. Heavy metals replace minerals on cell membranes. Fluoride and bromide replace necessary iodine. 

Xenoestrogens from pesticides and BPA in plastics are linked to obesity and breast, prostate and other cancers because they increase your accumulated exposure to estrogen. 

Electro-magnetic frequencies are bombarding us 24/7. Cell phones and other devices that transmit electro-magnetic frequencies disrupt the body’s energy flow. Refuse smart meters as long as you can and use "airplane mode" on your devices whenever possible. Keep your cell phone and other wireless devices away from your bed at night.

Radiation is a known cause of cancer. It causes cells to mutate and suppresses the immune system.  Cell phone use in young people under the age of 20 increases their risk of brain cancer five times. It is important to keep cell phones away from the head when talking on them and off the body when not in use. It is estimated that 50% of all cancers in 2020 will be induced by medical X-Rays and drugs. 

Chemotherapy is highly toxic. It can damage organs, suppress the immune system, and cause secondary cancers. Chemo kills fast growing cells, including cancer cells, but not cancer stem cells, which are the dangerous ones. When cancer comes back with a vengeance, this is why. Chemo can be lifesaving for some cancers. For the most part, its long term benefits are estimated at 2.1%. It causes a host of serious side effects including death and earlier death than patients who refused treatment.  This article explains the serious downsides of chemo.

Vaccines are also implicated in certain cancers. They often contain known carcinogens such as mercury and formaldehyde. In a vaccine, viruses are embedded in living cells. They also contain stray viruses. The virus, SV40, which is in the polio vaccine, is known to cause non-hodgkins lymphoma.

It's scary to think that what causes cancer are the very medical procedures meant to treat cancer and protect us from disease, as do the foods they sell to feed us.

Microbes and Cancer

In the 1930’s, Dr. Royal Rife did a great deal of research exploring the microbe-cancer connection. He made a discovery that today still explains what causes cancer.

Dr. Rife injected mice with a specific virus and they all got cancer. When he killed the virus inside the cells with his electromedicine device, the cancerous cells reverted back to normal.

It appears that when cell membranes weaken because of poor diet and toxins, opportunistic microbes can get inside the cell and create problems. They eat the glucose intended for the energy producing mitochondria. They excrete harmful hormones, very acidic mycotoxins, and enzymes that help them multiply. The thick protein coat they created on the cell membrane blocks oxygen and attracts more glucose for them to eat. This coating also makes the cell invisible to the immune cells that would normally kill them. 

Physical inactivity and Cancer

A newly published study of 147,000 people followed over 17 years revealed a startling find. Especially in women, too much sitting is a risk factor for cancer The study concluded that women sitting more than six hours a day have 30 percent higher risk of developing invasive breast cancer, ovarian cancer, and multiple myeloma (a blood cancer) than women sitting less than 3 hours. They have a 10% greater chance of developing any type of cancer.

What is most surprising that the amount of daily physical activity and weight did not affect these statistics.  Obese men who sit most of the day had an 11% increase in cancer rates. (Source: American Cancer Society Cancer Prevention Study II Nutrition Survey cohort published summer 2015, Journal of Cancer Epidemiology, Biomarkers & Prevention)

It is important to note that another study published in the Annals of Internal Medicine implicated sitting as a cause of dying younger regardless of physical activity. It appears that excess sitting alters metabolic chemicals in your body and make you susceptible to chronic diseases.

Cancer and the Immune System

“No doctor has ever healed anyone of anything in the history of the world; the human immune system heals and that is the only thing that heals.” ~Bob Wright, founder of the American Anti-Cancer Insitute

 “Cancer first and foremost is a problem with the immune system. You cannot have cancer if you have an intact immune system.” ~Dr. Rashid Buttar, D.O. 

A healthy immune system is a major factor in preventing and healing cancer. Of the different types of immune cells, only natural killer cells can see and kill cells that are turning cancerous. 

It may be impossible to stop cells from going wrong because of all the toxins we are exposed to, but a healthy immune system will quickly eliminate them. What causes cancer to get away with growing and spreading is a compromised immune system. If you have cancer, assume your immune system is not up to par. 

This can happen for any number of reasons including stress, lack of sleep, antibiotics, too much sugar, lack of necessary nutrients, and toxins. 80% of our billions of immune cells are made in the mucosal lining of the intestines. Good bacteria play an important role in keeping the immune system primed to fight off invading bacteria.

The health of the epithelial lining of the GI tract is important to the health of the immune system and good bacteria. This lining protects you from what you take in as well as metabolic waste. If the lining gets damaged by GMOs, heavy metals, or toxins, the gut becomes inflamed and leaky or dysbiotic. When this happens, the environment becomes inhospitable to good bacteria. This creates the opportunity for yeast and bad bacteria to overgrow.

When fungus levels get too high, the immune system attacks it, which creates a toxic environment i the GI tract. If the environment becomes too toxic, the immune system suffers. Local cells may respond to the toxicity by changing to a cancerous form that can survive in that environment. 

Final Thoughts on What Causes Cancer

No matter what kind of cancer you have, it’s important to remember that cancer is more than a tumor. Except in the case of genetic defects, it is not a disease. It is a symptom of dis-ease.  What causes cancer is that something went wrong in the body. The body has to be made well to heal it.

Conventional treatments only address the symptom of rogue cells, and not the what causes cancer cells to get that way. Radiating, cutting and poisoning a sick body does not make it well. These treatments may kill the patient or make the cancer worse.

Chemotherapy may kill off the bulk of cancer cells, but it is toxic ad weakens the immune system. It appears to make dangerous cancer stem cells more aggressive. They are the cells that metastasize and come back after treatment with a vengeance. 

There are many answers to the what causes cancer question because cancer is a complex disease. Thankfully, with the exception of genetics and some environmental toxins, you can control and limit many of them to reduce your risks. Cancer is often preventable.

More good news is that less harmful, more effective therapies are being developed and used in medical communities. These include alternative cancer treatments and different types of immunotherapy. Anti-cancer foods, herbs, detoxing, and supplements address what causes cancer at the root.  They are potent prevention as well.

If you or a loved one already has cancer, a comprehensive, natural, holistic approach, along with appropriate medical intervention can help you recover your health and become cancer-free.  Remember that as long as you have breath, there is hope.
