While breast cancer awareness is very high, actual knowledge is surprisingly low. There are a number of myths that can impact your ability to learn more about your own personal risk factors.
MYTH: Breast cancer is inherited only from a mother’s side of the family.
FACT: Breast cancer is equally inherited from both a mother’s and father’s side of the family.
While the family history of both parents can contribute to your breast cancer risk, the rate of inherited breast cancer is very low – only about 5-10 percent. Certain groups, like Ashkenazi-Jewish women, can have a higher risk if they have the genetic marker BRCA 1.
MYTH: Underwire bras increase your breast cancer risk.
FACT: Wearing a bra of any type does not increase your breast cancer risk.
Wearing a bra – or not wearing a bra – has no impact on your cancer risk. Sleeping in a bra also does not increase your risk.
MYTH: Antiperspirants can increase breast cancer risk.
FACT: No increase in risk is seen with antiperspirant use.
No antiperspirants or deodorants have been demonstrated to raise your risk of breast cancer.
MYTH: Keeping your cell phone tucked in your bra raises your breast cancer risk.
FACT: Since current results are unclear, active scientific study is underway to determine if storing a cell phone in your bra raises your risk. In the meantime, it’s best to keep your phone out of your bra and store it somewhere else.
