I suspect my mother had mammos less than 3-4 times in her whole lifetime.

She's clear..at 75. She has other long-term problems....high blood pressure and abit of gout.

(Oh yea, she still has excellent teeth. Maybe the best in the family so far.)
I did have an aunt who started to have abit of breast cancer. But she died from totally different reasons at 82.

I come from an extended family of many women. No. of females across 3 generations dominate by 70% over no. of males. So far the breast cancer is very low. Just that aunt I mentioned. Maybe there's another woman I don't know. But this is out of 30+ women.

We'll see. Dietary changes, environmental factors, etc.
