Introduction
Cancer is scary enough without the myths that surround it. Let's debunk five common misconceptions with facts.
Myth 1 - Most cancers are caused by inherited gene mutations.
Contrary to popular belief, only 5% to 10% of cancers are linked to inherited gene mutations. The majority of cancers result from lifestyle choices, environmental factors, and aging. To reduce your cancer risk, avoid smoking, limit sun exposure, stay current on vaccines, drink less alcohol, avoid processed meats, and maintain a healthy weight.
Myth 2 - Deodorant causes breast cancer.
Multiple studies, including one published in the ‘Journal of the National Cancer Institute’, found no significant link between deodorant use and breast cancer. The amount of aluminium absorbed from antiperspirants is minimal, less than what is consumed through food. While deodorants do not pose a significant health risk, it is advised to avoid them before mammograms to prevent interference with imaging results.
Myth 3 - Eating less sugar starves cancer cells.
All cells, including cancer cells, need glucose. A low-sugar diet won’t starve cancer cells because the body produces glucose from other sources. While a high-sugar diet can lead to weight gain and increased cancer risk due to higher insulin levels and inflammation, reducing sugar intake won't directly shrink cancer cells, as highlighted by a study in ‘Cancer Research’.
Myth 4 - Cell phones cause brain cancer.
Cell phones emit non-ionizing radiation, which is too weak to cause genetic damage. Extensive FDA research shows no increase in brain cancer rates since cell phones became widespread. To minimize exposure, keep your phone away from your body. More pressing radiation concerns include sunlight and radon, which is why regular home radon testing and UV protection are essential.
Myth 5 - Aspartame is a major cancer risk.
Aspartame, an artificial sweetener, is deemed safe in typical consumption amounts. Despite its classification as a possible carcinogen, major health organizations like the World Health Organization and the International Agency for Research on Cancer maintain that it’s safe within established limits. To reach potentially harmful levels, one would need to consume far more than a typical daily intake, as noted in a comprehensive review in ‘Critical Reviews in Toxicology’.
By debunking these myths, we can focus on genuine cancer prevention measures and reduce unnecessary fears. Making informed lifestyle choices remains the best strategy to lower your cancer risk.
