Welcome @pnienaber I'm sorry that your wife passed from with insidious disease.
'm a guy who was diagnosed with Stage IIIB Inflammatory Breast Cancer in 2014, aged 64. I started with chemo to reduce the tumour size and settle down the skin. I had a fair old time with the chemo, few side-effects. Did FEC and Taxol. Then came the surgery which consisted of a full mastectomy and the removal of all 23 lymph nodes under the arm. Two showed cancer. Then it was off to the radiation for 33 doses. For the past seven years I've taken the hormone blocker Tamoxifen. I'm in remission and doing well. Five years ago I managed to get diagnosed with Prostate Cancer nd was treated with a robotic prostatectomy. All good now.
Re the chemo, everyone has a different reaction. You will be offered anti-nausea meds and these will help. My oncologist gave me this advice at the start of treatment: don't have any pre-conceived notions about any state of treatment. That's my advice to you. Chime in here whenever you want a friendly ear. Everyone understands the trip you are going on. Good luck!
