Dear Doctors, Mere mom ka treatment chal horahai hai for breast cancer. Alhamdulillah 6 chemo session have been done. now oncologist refer to surgeon but surgery ka appointment 2 weeks ke bad ka mila hai. My 1st question is chemo session ke kitni din bad surgery karwa sakte hain because 2 weeks bad chemo ko 5 weeks hojayge kya wait kara ja sakta hai Second, abhi jo 6 chemo huwi hain unmay (Taxotere + Carboplatin + Herceptin) di gayi hain but hamare surgeon ne (Perjeta) ka pocha ya bhi dain but oncologist ne suggest nahi kara unhone kaha hai after operate Herceptin dainge every 3 weeks for 8 months. Please oncologist guide kare kya (Perjeta) bhi dena hota hai. Shukriya,
