The liver is the second largest organ in the human body but when cancer develops, there are not usually many obvious symptoms. With common complaints including fatigue, loss of appetite, or even just feeling unwell - it can be easy to dismiss an early warning sign as another part of day-to-day life.
However, as the liver is located on the right side of your abdomen, when cancerous cells begin to multiply the organ can start to apply pressure on your stomach. This means that liver cancer's biggest red flag is not actually to do with the liver.
Cancer Research UK says that one of the key signs is "a lump in the right side of your abdomen", caused by the liver swelling and protruding into the gut. For this reason, another key indicator is a swollen stomach and not feeling hungry.
