It is scary, but you are still young. There are amazing medical advances every day. In the area of fertility, this came out recently:

"German scientists have manipulated human stem cells, extracted from bone marrow, into immature sperm cells....But the technique, which could also be adapted to counter female infertility by growing eggs in a lab, raises the prospect of children being born through entirely artificial means...."

That's pretty amazing. Maybe it is not something that will be perfected in the next ten, or even fifty years, but it certainly gives a lot of hope to people who are worried about whether or not they will be able to have children in the future. Who knows when we'll have this kind of stuff available to us?

There's also adoption, of course, which I think is a wonderful thing.

that's sad. I'm sorry to hear. I believe that is hard to cope, even the thought of not having children down the road. adoption is always a second hand choice. especially being that america is well consumed of cancer victims. do you usually have a properly healthy diet? any history of cancer in the early years of your family?
