Will additional chemotherapy cycles affect my father's health?

Question
My father has been diagnosed with infiltrating duct carcinoma. He has been advised for radical surgery and chemotherapy. Four cycles of chemotherapy have been completed. Doctor has advised for another 2 cycles. He doesn't eat well during chemotherapy. How is the number of chemotherapy cycles determined? The tumour size was 2 cm and one node was also affected. Will additional 2 cycles have any adverse effect on his overall health? He is 68 years old. Please advise.

Your father should undergo full courses of chemotherapy as advised by your doctor. For 7-10 days, the patients do have side effects of chemotherapy. Your father should be encouraged to take a high protein diet e.g. milk, curd, cheese, eggs, protinex, non-veg food, etc. Secondly, the excised specimen should also be tested for oestrogen and progesterone receptor and HER2-neu oncogene study. If found positive, he will be a candidate for further therapy with oral hormones, etc.
