My older sister has just been diagnosed with breast cancer also. I was the first one in our family to have breast cancer. My mom passed away in 2001 of ovarian. Because no one else in the family had breast, I thought it was a fluke and didn't get genetic testing. Now her doctors are recommending it. What a bummer. They think it is about 3cm but are running the tests now. She has a MRI on Monday. A mammogram caught it but she has been having one every year. I was diagnosed in 2003. Another sister had uterine in 2002. Not a good decade for our family.
