Too tired. It is one of the most common symptoms of cancer. We’re not talking about the usual kind of fatigue here – it’s the kind of fatigue that doesn’t go away. If changing your activity level or getting more sleep doesn’t help, see your doctor.
The fever does not go away. A rise in your temperature is usually a sign of an infection. But some cancers, such as lymphoma, leukemia, kidney and liver cancer, can cause it.
