min maxing cancer
using the breast cancer risk calculator at http://www.cancer.gov/bcrisktool/
and fooling around with it, it looks like i can cut my lifetime chance of getting breast cancer (starting at age 35) by two percent if I give birth before I turn 24 from what it would be if I never give birth. If I had had a kid before I turned twenty, I could have cut it by five percent. If I wait til after I turn 25, but before I turn 30, then it's back up to 11.3% lifetime risk. If i wait til after I turn thirty, it's up to 13.9%.
