Many cancer myths about cancer causes and treatments do nothing but increase anxiety. Some of these false claims may be fueled by bad information, while others grow out of the overwhelming fear that cancer prompts in people.


Whatever their source, these cancer myths can be very damaging as they spread. They can distract you from protecting yourself against known cancer causes, instead drawing your focus to things that have no impact on your chances of contracting cancer. And they can hurt cancer patients' chances of beating the disease by creating a sense of hopelessness or by enticing them to pursue unproven remedies.

Here are eight common cancer myths and the truth about each, according to leading authorities, including the National Cancer Institute, the American Cancer Society, and the American Society of Clinical Oncology.

1. The chance you'll die of cancer increases every year. More people are being diagnosed with cancer these days, but medical advances have improved survival rates and overall quality of life for cancer patients. The five-year survival rate for all cancers combined has shown steady improvement over the past three decades, and more than 60 percent of people diagnosed with cancer are still alive five years after diagnosis. There's been a steady decrease in the number of people dying from cancer, even as the overall population of the United States has increased.

2. You're more likely to develop lung cancer from urban air pollution than from smoking cigarettes. Breathing the air of a polluted city is much less likely to cause lung cancer than smoking cigarettes or being frequently exposed to secondhand smoke. The numbers speak for themselves: Nearly 9 in 10 lung cancers, or about 87 percent, result either from smoking or exposure to secondhand smoke.

3. Using certain antiperspirants, shampoos, deodorants, or other personal toiletries can increase your breast cancer risk. This rumor holds that harmful substances in these products are absorbed through the skin or enter the body through nicks or cuts. Research has found no evidence to support this claim, including at least one epidemiological study that directly compared women with and without breast cancer and found no link between their health and their toiletries.

4. Cell phones cause brain cancer. As of yet, there is no credible evidence that exposure to electromagnetic fields emitted from cell phones or other personal electronics can cause cancer. One recent study found that cell phone users had no elevated risk for a number of different cancers, even if they'd been using the phones for a decade or more. More research is ongoing, but for now the risk seems minimal.

5. Fluoridated water increases your cancer risk. Rumors about fluoride in drinking water causing cancer have swirled for decades, but no evidence has ever been found to support this myth. The U.S. Centers for Disease Control and Prevention recently produced a survey of existing research that found no credible evidence of an increased cancer risk in people who drink fluoridated water — and half the U.S. population does.

Arming yourself with knowledge — the truth rather than myths — is the best way to fight every type of cancer.

  1. More information about the biological effects of non-ionizing radiation from wireless technology is coming out every day. Enough is not being done by cities, counties, states and the Federal Government to protect us from the potentially devastating health and environmental effects. Through the 1996 telecommunications act the telecoms are shielded from liability and oversight. Initially cell phones were released with no pre-market safety testing despite the fact the Government and the Military have known for over 50 years that radio frequency is harmful to all biological systems (inthesenewtimes dot com/2009/05/02/6458/.). Health studies were suppressed and the 4 trillion dollar a year industry was given what amounts to a license to kill.
    On it's face, the 1996 telecommunications act is unconstitutional and a cover-up. Within the fine print city governments are not allowed to consider "environmental" effects from cell towers. They should anyway! It is the moral and legal obligation of our government to protect our health and welfare? Or is it? When did this become an obsolete concept? A cell tower is a microwave weapon capable of causing cancer, genetic damage & other biological problems. Bees, bats, humans, plants and trees are all affected by RF & EMF. Communities fight to keep cell towers away from schools yet they allow the school boards to install wi fi in all of our schools thereby irradiating our kids for 6-7 hours each day. Kids go home and the genetic assault continues with DECT portable phones, cell phones, wi fi and Wii's. A tsunami of cancers and early alzheimer's await our kids. Young people under the age of 20 are 420% more at risk of forming brain tumors (Swedish study, Dr. Lennart Hardell) because of their soft skulls, brain size and cell turn over time. Instead of teaching "safer" cell phone use and the dangers of wireless technology our schools mindlessly rush to wireless bending to industry pressure rather than informed decision making. We teach about alcohol, tobacco, drugs and safe sex but not about "safer" cell phone use. We are in a wireless trance, scientists are panicking while young brains, ovaries and sperm burns.
