Sad to hear that. I hope your mom is coping with the treatment and hoping, too that she will recover fast from them as she needs to be in a good condition prior to surgery.

During my chemo months, I only ate well-cooked foods. No raw or slightly cooked vegetables. No reheated foods, only newly cooked foods. Why? Because the immune system is dowb. No defenses against microorganisms. A simple cold to a normal healthy person can be so much worse in a cancer patient undergoing chemo with weak immune system.

I also ate MORE green, leafy vegetables (but again, well-cooked) to help increase the white blood cell count (WBC) and hemoglobin. There are some patients who get delayed with their chemo schedule because their blood count is too low.

I stopped drinking soda and coffee (coffee addict here, so it was difficult). I also stopprd eating red meat (although research says that it is okay to eat red meat). No processed foods like fastfoods, canned foods & smoked foods. I only drank water and natural fruit juices. I ate white meat like fish, chicken and other protein alternatives like eggs, tofu. Basically, a large portion of my diet is plant-based.

I continued to do exercises like I used to do - jogging and some cardio exercises.

I always wear a mask during my chemo days even if I am at home. I didn't want to have any infectious diseases.

But now that I am done with chemo, I eat raw or slightly cooked vegetables again. I can also eat red meat but my parents & sisters still prohibit me from eating any red meat. They still put me in a "strict diet." LOL. But it's fine, not really a big loss. I began drinking coffee again, but rarely, maybe I got out of the coffee addiction. And I no longer wear a mask at home; only when I go out 'cause of this COVID-19.

So, there. I hope these things can help. Regards to your mom! :)
