​Breast Cancer Risk Remains High for BRCA+ Women After Age 50

I'm 90 yrs.old, in perfect health, but recently diagnosed with breast cancer. I've chosen not to have any treatment and my dr. didn't disagree. She admitted that at my age, the treatment can be very debilitating and even worse than the disease. So I've chosen that route. Has anyone else done that and I'd like to know how they handled it.
