Question: Hi. If someone had cancer and didn't know that they did, what signs and effects on your body, should you be watching out for? (depending on what kind of cancer you have, e.g, skin cancer, brain cancer etc)

As you mentioned in your question, depending on the type of cancer you should look for some symptoms or others. In the case of skin, if a mole changes in colour or size, it should be checked by a doctor. For brain cancer is a bit more difficult, because some of the symptoms are headaches or hard migraines, which don’t need to be cancer in all cases. In general, we can check ourselves regularly by going to the doctor, or if we notice any weird change in our bodies, but we shouldn’t get too paranoid about it!
