Top 10 Causes of Cancer

An ounce of prevention is worth a pound of cure.
Benjamin Franklin

World Cancer Day is on February 4th, and held to bring more awareness and ultimately reduce deaths from the disease. Cancer is when there is an uncontrolled growth and division of abnormal cells. There are more than 200 cancers. To prevent cancer, we must identify the root of the problem.

Here are the ten main causes of cancer:

I. Genetics

We are all predisposed to disease if we mismanage our genes.
-Mark Sisson


Some cancers are linked to our genetics.

II. Obesity

About 10 percent of all cancer deaths among non-smokers are related to obesity.

Obesity has been increased risks of certain cancers including colorectal, pancreatic, liver, and breast cancer to name a few.

III. Radiation

Radiation, unlike smoking, drinking, and overeating, gives no pleasure, so the possible victims object.
Issac Asimov


Frequent exposure to radiation from such sources like the sun, radon, and UV rays can cause cancer. The American Academy of Dermatology recommends wearing a sunscreen with SPF of at least 30 that includes broad-spectrum protection.

IV. Diet

You can’t exercise your way out of a bad diet.


Some foods can increase cancer risks like canned food, charred meats, and processed meats. You can consume certain foods that also reduce cancer risks like green tea and leafy greens.

V. Consumer Products

We are losing the war against cancer. The prohibition of new carcinogenic products, reduction of toxins in use, and right-to-know laws — these are among the legislative proposals which could reverse the cancer epidemic.
-Samuel Epstein


Some products like food containers, plastic bottles, non-stick cookware, shampoos, artificial sweeteners, toothpastes, soaps, air fresheners, nail polish, and even baby powders can contain carcinogenic chemicals so be mindful in what you use.

VI. Smoking

Smoking helps in losing weight, one lung at a time.


Cigarettes contain thousands of chemicals and almost 70 known carcinogens that cause cancer. Secondhand and thirdhand smoke can be harmful too, so try to avoid it when you can.

VII. Alcohol

WARNING: Drinking distilled spirits, beer coolers, wine and other alcoholic beverages may increase cancer risk and, during pregnancy, can cause birth defects.
-Proposition 65


According to the CDC, excessive alcohol consumption can cause cancers of the breast, liver, larynx, mouth and throat, esophagus, and colon and rectum.

VIII. Infection

Neglect starts out as an infection then becomes a disease.
-Jim Rohn


Infections can increase cancer risks by lowering the immune system, making your body more susceptible to some cancers. Infections can also cause inflammation that can alter cell states and lead to cancer.



We won’t have a society if we destroy the environment.
-Margaret Mead


There are carcinogens that we are exposed to in the environment that pollute the very air we breathe. Some examples are cigarette smoke and asbestos. Minimize exposure to the environmental toxins that you have control over.


Sedentary Lifestyle

Your genetics load the gun. Your lifestyle pulls the trigger.
-Mehmet Oz


Physical inactivity increases risks not just for cancer but also for diabetes, cardiovascular disease, depression, and osteoporosis. The World Health Organization recommends adults exercise at least 150 minutes or moderate aerobic activity per week or 75 minutes of vigorous aerobic activity a week.

Live healthy and prevent cancer!
