Genetic mutations: This is mostly a random event. There's a natural instability in the human genome even if you are never exposed to anything that's obviously a mutagen. The other factors that place you at risk for breast cancer (nulliparity, brca1 / brca2 mutations, etc.) are risk factors here, but no woman (and actually no man either) is immune.

3-5 weeks: It depends on healing after lumpectomy, but radiation generally starts about 4 weeks later. Radiation generally takes 6-7 weeks to complete.
