People receiving or have recently finished cancer treatment should avoid some foods entirely. These include cold hot dogs or deli lunch meat (cold cuts) including salami, soft cheeses such as blue-veined, Brie, Camembert, feta, and goat cheese. There’s a lot more foods listed.
@Afraser, I thought I would be fine with spicy food which I love, so had a mild spicy vegetarian dish for dinner one night. I could feel it burning my mouth and next day started developing mouth ulcers. I bought something from the chemist which cleared them within a few days so no more spicy foods for me after that experience. I’ve started trying some mildly spicy things in the last two weeks and they haven’t caused any problems (but still taste spicier than they should) 😛
