Symptoms of kidney cancer
Some symptoms that could be signs of kidney cancer include:
- Abdominal pain
- Blood in the urine (hematuria)
- Feeling especially tired
- Fever that doesn’t go away
- Low back pain, especially on one side, that wasn’t caused by an injury
- Mass or lump on your side or lower back
- Weight loss without a change in diet or exercise habits
- Loss of appetite
These also could be symptoms of other kidney disorders. It’s important to see a doctor if you have any of these symptoms.
Diagnosis of kidney cancer
You may not have any noticeable symptoms if your kidney cancer is in an early stage. If your doctor suspects that you may have kidney cancer, you may need one or more lab tests. Some of the lab tests we use when diagnosing kidney cancer include:
- Blood chemistry
- Complete blood count (CBC), which measures the amounts of different cells in the blood
- Urinalysis (urine testing)
These tests are not conclusive for kidney cancer, but abnormal test results can suggest that something is wrong. We often first locate kidney tumors when we perform imaging studies for other reasons, such as if you’ve had some sort of traumatic injury that requires imaging for diagnosis.
If you were referred to us from a doctor outside Henry Ford Health System, our radiologists and urologists will evaluate your test results. You may need special renal computed tomography (CT) scans or additional tests so we can determine the best course of action.
What are the next steps?
If we locate a kidney tumor or mass during the course of a CT scan or a magnetic resonance imaging (MRI) scan, we may recommend that you have a needle core biopsy. This test lets us take a sample from the tumor to determine if it’s cancerous.
We’ll refer you to our kidney cancer program if we diagnose you with kidney cancer. There, our kidney cancer doctors will work to create a customized treatment plan for you.
