The early stages of a kidney tumor may generate no symptoms at all. As the tumor grows and the condition progresses, the tumor may begin to exhibit symptoms that result mostly from pressure put on other organs and the pain associated with the location of the tumor. A kidney tumor will normally show symptoms at advanced stages whether it is cancerous or not.
A kidney tumor may begin to show itself with noticeable abdominal symptoms. There may be a hard lump that appears on the abdomen that can be detected through a physical examination, or it may be visible to the naked eye. You may begin to notice a swelling in the abdomen, and it is also possible that you will begin to see larger than normal veins appearing at the surface of the abdomen. The tumor may also be putting pressure on internal organs and this pressure may result in sharp abdominal pain.
A kidney tumor may begin to affect your appetite. You may find yourself losing your appetite, and this may result in a noticeable weight loss. You may also start to feel weak due to your decreased appetite, and you may also start to suffer from a lack of energy or a growing feeling of fatigue. You may also start to feel achy and in general poor health as the result of a kidney tumor.
Blood Flow Symptoms
One of the more common symptoms of a kidney tumor is blood in the urine. The blood mixing with your urine may not be very noticeable at first, but over time you will notice that your urine is becoming reddish brown color almost resembling rust. Another blood flow symptom associated with a kidney tumor is hypertension, also known as high blood pressure. You may also begin to feel symptoms of anemia which is a low red blood cell count. These symptoms include dizziness and fatigue.
A kidney tumor can also trigger some flu-like symptoms such as fever and body pain. You may begin to experience a recurring fever that can reach very high temperatures and become extremely uncomfortable. You may also start to feel a sharp pain in the side of your body that seems chronic and does not leave. The recurring fevers may amplify this pain in your side.
A kidney tumor may require a series of tests to determine its location and to determine if it is cancerous or not. These tests may include a blood test, a urine test and an imaging test such as a CT scan or ultrasound to determine the exact location of the tumor. Once the tumor is located then a biopsy may be used to determine if the tumor is cancerous or not.
