Early Symptoms of Kidney Cancer

When kidney cancer first develops, it usually causes no symptoms. For tumors of sufficient size you may experience symptoms such as: stomach pain, fatigue, blood in the urine and back pain. As kidney tumors become larger they can cause more distinct complications as they place pressure on organs in the abdomen.

Additional warning signs of kidney cancer

In addition to abdominal pain and general fatigue, some of the most common symptoms of kidney cancer include:

  • Blood in the urine
  • Unexplained weight loss
  • A chronic fever that is not caused by a viral or bacterial infection
  • Anemia
  • Swelling in the feet or ankles

How a physician can determine the cause of your symptoms

If you’re experiencing one or more of these symptoms, your physician may recommend several different diagnostic tests, such as bloodwork, urine tests, ultrasounds, computed tomography (CT) scans and magnetic resonance imaging (MRI) scans.

  • In many cases, kidney cancer is detected before it spreads to other organs. Patients with early-stage kidney cancer often have a variety of treatment options, which typically are associated with a favorable outcome.

At Moffitt Cancer Center, we offer a number of advanced tests for suspected kidney cancer, as well as many evidence-based and specialized treatments. You can discuss your symptoms with an oncologist who exclusively specializes in kidney cancer, which offers an extra level of assurance that you will receive a prompt and accurate diagnosis. Or, if you have already been diagnosed with kidney cancer, you can turn to Moffitt for a reliable second opinion or treatment consultation. We welcome people with all types and stages of kidney cancer and no referral is required to request an appointment.
