1 Breast cancer is common, and early cases are very treatable

Breast cancer is the second most common cancer in women (behind skin cancer), with more than 300,000 American women diagnosed this year. Thanks to screenings (such as mammograms, clinical breast exams, and MRIs), about 66% of cases are found when the cancer is easiest to treat-when it is found in its earliest, localized stages, the survival rate is 99%.

2 YOU SHOULD GET TO KNOW YOUR BREASTS

We used to be told to examine our own breasts monthly, but the rules aren't so rigid anymore. "We learned through large research studies that teaching women how to do a self-exam didn't reduce breast cancer mortality," says Susan Brown, R.N., senior director of health information and publications at Susan G. Komen. "Most women didn't do it even when told to." Instead, keep an eye out for any changes. "What we have found is that women notice breast changes in the shower or when dressing, or a partner notices. Being familiar with your breasts is what's important," says Brown.
