7 Things That Probably Don't Increase Breast Cancer Risk

— -- intro:About 1 in 8 women in the United States will be diagnosed with invasive breast cancer by the age of 85—and it's probably safe to say that we will all know someone who's affected by this disease in some way. With stats like that, it's no wonder that breast cancer is the most-feared cancer among women. Unfortunately, that fear breeds misinformation, and you may be wasting your time and energy avoiding products, foods, and behaviors that have no scientifically proven effect on your breast cancer risk. Here are 7 of them.

10 Celebrities Who Battled Breast Cancer

It's a myth, and a new study proves it, finding no relationship between breast cancer and any aspect of wearing a bra—not cup size, not whether or not it had an underwire, not how old you were when you started wearing one. "It was a well-done study and it was pretty reassuring," says Kari B. Wisinski, MD, a medical oncologist with the University of Wisconsin Carbone Cancer Center in Madison.

An additional concern that some women have is that mammography may miss some breast cancers in women with implants. This, too, is largely unfounded. "We do additional mammographic views on women who have implants," explains Therese Bevers, MD, medical director of the Cancer Prevention Center at the University of Texas MD Anderson’s Cancer Center in Houston. Doctors also perform x-rays to get a more complete picture.

There's no evidence to back that claim up, nor is there any evidence to support another concern that's been voiced: that the preservatives found in deodorants and antiperspirants, called parabens, cause cancer. (Besides, most of the products on the market no longer contain parabens.)

Although some studies have shown weak evidence in support of this, others have found that coffee might even lower the risk of breast cancer in certain groups of women. Coffee beans are rich in antioxidants, and recent research shows that coffee is actually the number-one source of antioxidants in the American diet. More wins for coffee: it's been linked to improved circulation, less pain, better memory, and muscle preservation. For now, consider caffeine a non-risk. To reap caffeine's rewards, stick to less than 16 ounces (two cups) a day.

15 Worst Things You Can Say to Someone Battling Breast Cancer

Meanwhile, multiple studies have shown that regular mammography can help lower deaths from breast cancer in women aged 40 to 75, especially among those over 50. The American Cancer Society recommends that annual mammograms starting at age 40 for women at normal risk for the disease.

Magnetic resonance imaging (MRI) and ultrasound are sometimes used in addition to mammograms to screen for breast cancer. Neither of these techniques use radiation. MRIs involve the use of magnets while ultrasound uses sound waves.

At least two rigorous studies failed to find any link between the two, including a landmark 2003 study investigating the higher-than-average breast cancer risk among women living on Long Island. There is no evidence that electromagnetic fields raise the risk for other forms of cancer, either, says Dr. Wisinski.

These facts may have led to the myth that chemical hair straighteners or relaxers cause breast cancer in African-American women. A 2007 study of about 50,000 African-American women debunked the myth, finding no link between such beauty products and breast cancer.
