Kidney cancers often do not cause symptoms in the early stages of the disease, and sometimes cause very few symptoms, even if they have grown extensively or spread elsewhere.
The most common symptoms of kidney cancer are:
- blood in the urine
- low back pain on one side
- a lump in the abdomen, side or lower back
- appetite loss
- unexplained weight loss
Many conditions can cause these symptoms, not just kidney cancer. If you have any of these symptoms, talk to your doctor. Blood in the urine should never be ignored.
