People who have been diagnosed with cancer often begin looking for information about their condition. In addition, well-meaning family members commonly search for answers to their many questions. However, with an abundance of information out there, there is bound to be some which is inaccurate. As a result, many cancer myths have been circulating for years.

It’s important to consult with a doctor or a reputable source for cancer information. Reputable sources include the American Cancer Society or the American Society of Clinical Oncology. Here are some common myths debunked.

Myth: Cancer is hereditary.

Truth: Although cancer starts in the genes, just because a parent or sibling has cancer doesn’t mean their relatives will also contract the disease. Only 5 to 10 percent of cancers are hereditary.

Myth: Cancer is a death sentence.

Truth: There are a number of successful treatments for cancer. In fact, 60 percent of people live 5 or more years after an initial diagnosis.

Myth: Antiperspirants cause cancer.

Truth: Although the body can absorb the aluminum that is contained in many antiperspirants, there is no definitive proof that these products cause cancer.

Myth: Most people who develop cancer have a weakened immune system.

Fact: The majority of common cancers are not the result of a compromised immune system. The strength of one’s immune system does not affect risk of contracting cancer.

Myth: Some people are just too old for cancer treatment.

Fact: Cancer treatment is not limited by age. However, treatment may be limited by other pre-existing conditions.

Myth: Eating sugar makes cancer grow faster.

Fact: Although cells need sugar for growth, reducing sugar intake will not be a successful treatment for reducing cancer.
