If you experience any of these symptoms most common with later stage RCC, it may not be cancer. Instead, these symptoms can be caused by a wide range of conditions that might not be serious.
Renal cell carcinoma (RCC) is the most common type of kidney cancer, accounting for
Risk factors for this type of cancer include:
- a family history of RCC
- high blood pressure
- some hereditary kidney diseases, such as polycystic kidney disease
- smoking
- obesity
Surgical treatment for RCC is often recommended, depending on what stage the cancer is at. The survival rate is fairly high if the cancer is caught early, with a five-year survival rate of
If you have RCC, you’re not likely to experience symptoms until the later stages when the tumors have grown larger.
RCC is most often diagnosed when a person is being examined for another reason. A tumor may show on an ultrasound or a CT scan before a person experiences any symptoms.
The symptoms that are caused by kidney tumors (like bladder infections or kidney stones) are similar to those caused by other conditions.
If you experience any of the symptoms, you should see your doctor.
1. Hematuria
A tumor caused by RCC can cause you to have blood in your urine, a phenomenon known as hematuria. The amount of blood may be visible, giving your urine a pink tint. It may also be a microscopic amount, only visible by examining a urine sample under a microscope or by performing a test to detect small amounts of blood.
2. Lower back pain
A tumor in one (or both kidneys) that’s grown to a significant size can cause pain. If you have pain that originates in your kidney, you may feel pain in your lower back and to the side, just below the rib cage.
Pain caused by a tumor is steady and won’t go away, whereas pain from a strained muscle may change or lessen with movement. If you have pain from an injury, it’s unlikely to be related to a kidney tumor.
3. Lump
If a kidney tumor caused by RCC has grown very large, it may produce a noticeable lump that extends outward from your body. The lump is usually low in your abdomen, either on your back, under your rib cage, or on your side. To produce such a lump, the tumor has to be fairly large.
4. Anemia
Anemia is a condition that can be caused by many different factors. It refers to having low levels of red blood cells, which carry oxygen. RCC can cause anemia, which may make you feel tired, sluggish, and run down.
5. Fatigue
Having a tumor in your kidney may cause you to feel fatigued. One reason may be anemia caused by the cancer. Your fatigue could also be a result of the cancer cells competing with your healthy cells for nutrients. You may be fatigued for many reasons, such as having a cold.
If you feel unusually tired for a long period of time and you can’t explain it, contact your doctor.
6. Fever
RCC may cause you to have a fever. A fever is the natural result of your immune system fighting an infection, so having a fever may be caused by a number of illnesses. If you have a fever and no other symptoms of an infection, or if a fever doesn’t get better after an illness, you should see a doctor.
7. Weight loss
Unexplained weight loss is a possible symptom of RCC. If you’re not dieting, or your weight loss is accompanied by fatigue and fever, you should see your doctor for a diagnosis. Cancer cells in the kidney can out-compete your healthy cells for nutrients, leading to unintentional weight loss.
If you experience any of the symptoms that are common with later stage RCC, don’t automatically assume you have cancer. These symptoms can be caused by a wide range of conditions, many of which aren’t serious.
If you do have RCC, you have treatment options that include surgery and medications. The earlier you receive a diagnosis for the cancer, the greater the chance that treatment will be successful.
