If my boyfirned plays wit my breats too much will I get sick? will I get lumps?Someoen told me I could get cancer from sleeping around. my aunt has breast cancer and I am scared. I’m afrayed to have sex, but i really like it. wat do i do?

This question is a serious question, so please give truthful answers. I have a friend that has the genital herpes virus and is pregnant, she wishes to breast feed her new born baby once its born, but didnt ask her doctor if it would be okay. Im trying to find information for her, so she can prepare herself and protect her baby once its born.

Can a mother, who is already infected with genital herpes, breast feed her 3 month old baby? Any chance of getting the baby infected through breast milk? She is not having an active outbreak right now.
My second question is in case she develops active infection during her lactation still can she breast feed? What precatuions should she take?
Any medical doctor to answer, please.
