It doesn't seem that unusual to me. Your body reminds me of my daughter's body. Your torso has the lean quality that her torso has. You are a young person, your body is still beautiful. The notion that your body is no longer beautiful is ridiculous.
Breasts are one aspect of a person and they are by no means the most important, the most salient.
To me, it seems as if I'm blossoming. I was very susceptible to illness, I just didn't feel good. But this is just a transitional period in your life. You are continuing to live. At this point the cancer has not returned.
