Renal Cell Cancer Symptoms
Patient Comments Read 13 Comments
In its early stages, renal cell cancer usually causes no noticeable symptoms. Symptoms may occur only when the cancer grows and begins to press on surrounding tissues or spread to other parts of the body. The symptoms vary considerably from person to person. Some people never develop any symptoms before the disease is discovered; the cancer is found when they undergo imaging tests, such as a CT scan, for another reason. In a study in the Journal of Urology, approximately 53% of people with localized renal cell carcinoma had no symptoms.
Symptoms of renal cell cancer may include the following:
Symptoms such as a mass that can be felt in the flank, pain in the kidney region, or weight loss are usually signs of advanced cancer. The early kidney cancers are usually asymptomatic, and either detected incidentally while testing for some other condition, or because blood found in the urine, which may or may not be visible to the patient.
Other symptoms may result from metastatic renal cell cancer in the bones, lungs, or elsewhere. If the disease attacks the bones, for example, it can cause bone pain, which is deep and achy.
Renal cell cancer can also cause a number of conditions called paraneoplastic syndromes. These are problems caused by the tumor when it releases cytokines (chemicals involved with the immune system) or hormones. Cytokines may or may not cause symptoms, and a person may unknowingly have one or more of the following symptoms.
