My father had breast cancer. I was pretty young at the time and I wasn't foresighted enough to think it was anything I should learn about, so I can't tell you much. I think he had some tissue removed on both sides. I don't know how it was discovered. I don't remember seeing any scars on him afterwards, but he was pretty hairy-chested and I seldom saw him without a shirt, and I never wanted to look closely anyway. I honestly couldn't tell you whether he had nipples or not after the surgery. I didn't notice any deformity, ever.

I'm guessing he was in his 50's when he had the cancer, and he died of heart failure at age 85. There was no recurrence of cancer. That's all I know.
