Symptoms may not appear until kidney cancer is in advanced stages. If you experience any symptoms, do not assume it is due to cancer. Many symptoms can be caused by other, less serious conditions. However, it is still important to discuss them with your doctor. Early detection and treatment improve outcomes for both cancer and other health conditions.
The most common symptoms include:
The kidney has several functions that affect the entire body. Other vague symptoms, like swelling in the legs from fluid collection (edema), may occur. Kidney tumors can also trigger other syndromes in the body, called paraneoplastic syndromes. They occur when the tumor secretes hormones that influence bodily functions.
