Breast cancer myths: How much do you know?

There are 3.8 million breast cancer survivors living in the US

ORLANDO, Fla. – October is National Breast Cancer Awareness month – a perfect time to educate yourself about the disease that impacts one in every eight women in the US. But there are a lot of fallacies when it comes to this common cancer.

“I just, I felt something, and I thought, huh, it was real tiny, but it just felt different,” Kristen Lyons, a breast cancer survivor said.

“I didn’t think anything of it because of my age, and I found blood in my bra,” Roshni Kamta, another survivor, said.

Kristen and Roshani are two in 3.8 million breast cancer survivors living in the United States.

Though there’s a lot of awareness, there’s also a lot of false information floating around.

A first myth: You must have a lump to have breast cancer!

The truth is many cancers are found on mammograms that may not be felt. And not all lumps are bad – in fact, 80 percent of breast lumps that are biopsied are not cancer.

Another claim: you’re not likely to get breast cancer if no one in your family has it.

The truth is only about five to 10% of breast cancers are caused by genetic mutations. And do mammograms always catch breast cancer? Studies show mammograms miss about 20%of breast cancers at the time of screening. And having dense breast tissue makes it more difficult to spot and raises your risk for breast cancer by two to four times.

“It just makes it more difficult for the radiologist to pick up any smaller tumor, if it’s present there,” Tricia Morino, an oncologist and hematologist said.

You may have heard that a mastectomy is a better option than a lumpectomy, but this is also false in many cases.

Recent studies have shown survival after a lumpectomy combined with radiation is equivalent to that of a mastectomy for most early-stage breast cancers.

Other common myths: bras with underwire, nipple piercings, and deodorant will cause breast cancer.

There’s no scientific proof that any of these will increase your risk. Some things that have been linked to breast cancer risk are using some forms of hormone replacement therapy for more than five years and drinking excessive amounts of alcohol.
