Nun boobs are good to go.

I had my second-ever mammogram yesterday, the first in over four years, and it was normal. I've been told the following things about my risk for breast cancer:

1. There's no data on trans women's breast cancer risk. Zippo. Nada.
2. However, the conventional wisdom speculation is that since I started hormones so late in life - 42, to be exact - my risk should be pretty low, all other things being equal.
3. Except of course that they're not equal. Having estrogen levels higher than anything that occurs in cisgender women, which my docs have always tried to avoid but have happened nevertheless, especially early on, is as you'd expect Not A Good Thing.
