If you experience any of these symptoms, do not assume it is due to cancer. Most of these symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.

Kidney cancer often begins with no symptoms and no pain. Often, cases are detected during an imaging test, such as a CT scan , for an unrelated condition.

As the disease progresses, the following symptoms may occur:

Blood in the urine

—The blood may be visible to the eye or detected during a routine lab test.

Lump in the abdomen

—This may be a sign of the growing tumor.

Pain in the side, back, or abdomen

—This may be a symptom if the pain is not a result of an injury.

The following symptoms may also occur, but are less common:

Increased blood pressure

—Kidneys play a role in blood pressure control, so disease in the kidneys can affect blood pressure.

Weight loss

—This includes unplanned and substantial loss of weight.


—This may include an increased temperature for no apparent reason that may come and go.

Swelling in the legs

—Fluid builds up in the tissue due to the cancerous mass restricting blood flow.

Kidney cancer may also cause a wide variety of other symptoms.
