Hi I had breast cancer operation in March this year and had Radiotherapy as I had too much oestrogen, my Radiotherapy finished in May, could you tell me if I am allowed to eat the following food: Tin Crab, fresh Crabsticks, Pickled onions n Jars, and shellfish e.g. Prawns, cockles, mussels and if I can eat quorn e.g sausagues, turkey slices and ham slices. I have read that it is not safe to eat any shellfish or the above? Thanks. Marian
