My MIL is diagnosed with BC with 7cm lump on her right side. Doctor suggested us to go with chemotherapy of 4 sittings and then surgery and targeted therapy. After 3 chemo's is done doctor insisted us to proceed with the surgery as it can be operable, but he also said that 1 more chemo should be given after surgery as 4 chemo and 4 targeted therapy is mandatory.
Can someone tell me why 4th chemo has to be given if it is operable now.
As she has few side effects of chemo we asked doctor whether 4th chemo can be given before surgery or not so that she can recover from the surgery fast if she does not have to take the chemo after surgery.
He said it can be given now and so we decided to go for 4th chemo now.
Kindly through some knowledge on the how many chemo's should be taken and when and why it has to be taken before/after surgery.
Note: ER,PR Negative HER Positive Stage 2 and 3.
