When to see a doctor: Recognising cancer’s symptoms

Various physical signs and symptoms might indicate cancer. The list we have included in this article is not all-encompassing, yet includes common symptoms seen in the case of cancer. Generally speaking, if you notice any major changes in the way your body works or the way you feel – especially if the symptoms persist or worsen – let a doctor know. If your symptoms have nothing to do with cancer, the doctor will find out more about what is going on and treat you appropriately. If it is cancer, you may well catch it in its early stages – giving yourself the best chance of remission.
