Just new and needing answers - husband needs chemo before he can have surgery. Does anyone have any advice on how to prepare and what to expect afterwards?

my husband has just been diagnosed with pleomorphic carcinoma in his abdomen. The initial plan was to have surgery to remove it. We’ve found out today that it is too aggressive and that he needs to have chemotherapy first. If the cancer responds to the chemo then he can have surgery. We are now waiting for a call from the oncologists to arrange an appointment. We are based near Durham so likely all treatment will be at the local hospital. I suppose I’m kind of just looking for someone to say it’s going to be ok. Or at least tell me how to prepare for chemotherapy and the after effects.

My dad died of cancer and this just feels different
