I think in the back of our heads, we all think we're invincible. We think that cancer can't possibly touch us. And then it does. Look around you. One in eight women that you see will be diagnosed with breast cancer in her lifetime.

According to the World Health Organization, breast cancer is the most common cancer among women worldwide, claiming the lives of hundreds of thousands of women each year. And while rare, an estimated 2,150 men will be diagnosed with breast cancer and approximately 410 will die each year.

If your mom, sister, dad or child has been diagnosed with breast or ovarian cancer, you've got a higher risk of being diagnosed with breast cancer in the future. Your risk increases if your relative was diagnosed before the age of 50.  But sometimes cancer strikes without warning. This is why it's so massively important to do monthly self checks and to keep up on your annuals and the breast exams that go hand-in-hand with them.

An annual with a breast exam is what alerted my brave friend, Mary Beth Walsh to her breast cancer and being vigilant with keeping up with her healthcare is what saved her life.

This is Mary Beth's story.
