When DH had chemo I was the one that got cold; usually not him. Nurses gave me a warmed blanket that felt wonderful. Don't know if all chemo centers/hospitals have a blanket warmer though.
When BFF had breast cancer a friend gave her an engineer's cap made from a pillow ticking type print with one pink ribbon on it. She loved it(she was quirky type dresser). But when she had stage IV lung cancer, she didn't like pink or any other color ribbons any more.
Also, did you know pink ribbons are only to symbolize breast cancer? There are many other colors for different types of cancers, and one color that stands for any type of cancer. Don't remember which is "for" what type. The chemo or doctor's office or Google could tell you what color stands for that particular cancer.
As for me if I had to have chemo I think I would like a cheerful light weight Minkee backed quilt.
