Symptoms of kidney cancer
Kidney cancers that are small don’t usually cause symptoms, because they can’t be felt or seen. Early kidney cancers are often diagnosed by chance when people are having tests or scans for some other reason.
Some possible symptoms are:
blood in the urine (haematuria) - it's very important to get this checked by your doctor
a lump in an area of the kidney that's found during an examination
a dull pain in the side between your upper abdomen and back
having an ongoing high temperature, night sweats, feeling very tired, or losing weight for no obvious reason.
Most people with these symptoms won’t have kidney cancer. They can be caused by other more common conditions, such as an infection or stones in the bladder or kidneys. But if you have any of these symptoms, it’s important to get them checked by your doctor.
