Causes of Cancer

Cancers are a group of diseases that have a variety of causes. Plants, animals and humans can develop cancers. Thankfully, 40 percent of cancers can be prevented.


Five to 10 percent of cancers are caused because of genetics. Your doctor may tell you that most cancer is caused by genetics, but that’s false. Research has been done to prove it. Most families have the same habits, and that’s why the same cancers run in families.


Environmental factors can increase your risk of developing cancer. There’s pollution in the air and the beauty products we use. You probably spend most of your time at work and in your home. It’s important to evaluate and eliminate the possible toxins you’re exposed to on a daily basis.

Cigarette Smoking

Cigarette smoking causes approximately 20 percent of cancer cases, and more than 90 percent of all lung cancer cases are caused by smoking. The carcinogenic chemicals in cigarettes can cause cancer.

Sleep Deprivation

Sleep deprivation increases your risk of colon cancer. Sleep deprivation is defined as getting less than six hours of sleep each day.


Research has shown that obesity increases your risk of developing cancer. Over 66 percent of humans in the U.S. are considered overweight or obese.


Cancer can take a long time to develop, and that’s the reason why most people diagnosed with cancer are elderly. Cancer is more common in the elderly, but it can develop and be diagnosed regardless of age.

Final Thoughts

Researchers have shown that cancer is 100 percent preventable. The best way to reduce your risk of developing cancer is to live a healthy lifestyle. If you’re overweight or obese, try to lose weight. If you smoke, try to stop smoking. Your chances of developing cancer will dramatically decrease. Be sure to get cancer screening exams.
