Hi, Thanks for writing in. The cancer is a large one and therefore aggressive treatment is required after surgery. The number of lymphnodes which are cancerous is significant. The treatment she is getting is acceptable. For the side effects she should try and have a calm mind. The hair fall might be slowed by wearing ice cap or cold cap during chemotherapy. This will help the hair to be strong at the roots and prevent shedding because of treatment. Please give her high protein diet. Please do not worry.
