Oh and in regards to being too skinny for chemo. This is irrelevant. Chemo doses are based on your weight. A significant number of women actually gain weight on chemo as steroids are used to assist with nausea as well as many other choices for controlling nausea.
My niece was always very thin and had no particular issue with her chemo treatment at all.
I myself managed to gain 28kg on chemo, even though I felt a little squarmy a lot I'd the time the 1st week if each cycle. Most people don't gain that much, I was just a bit special.
