Why would someone with a mutation in the brca1 gene have a higher risk of developing cancer earlier in life than someone without a mutation in the brca1 gene?

Mutations to either breast cancer gene BRCA1 significantly increase your risk of developing breast cancer and ovarian cancer when compared with the cancer risk of a woman without a BRCA gene mutation. Men with certain inherited BRCA gene mutations also face an increased risk of breast cancer.

geologic time scale (for gradpoint) =)

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
