It’s completely normal to be worried about what’s going to happen to your body and how you’re going to feel during your treatment. All cancers are different, and some treatments will take more of a physical toll on the body than others. Many people are aware of the possibility of hair loss and weight fluctuations, but side effects and when they appear all differ from person to person. The type of cancer you have and what stage it’s at will determine the treatment you have and how long it will go on for. Your GP, specialist and health team will be able to explain what you can expect, what is likely to happen during your treatment and some of the possible side effects.
