What does it mean to have a mass on your kidney?
A renal mass, or tumor, is an abnormal growth in the kidney.
Some renal masses are benign (not cancerous) and some are malignant (cancerous).
One in four renal masses are benign.
Smaller masses are more likely to be benign..
What percentage of kidney masses are cancerous?
Among the 2,675 tumors, 311 (12%) were benign while 2,364 (88%) were RCC. The odds ratio for association of malignancy with tumor size was 1.16 (95% CI 1.11–1.22; p<0.001), indicating that each 1cm increase in tumor size was associated with a 16% increase in the odds of malignancy.
Can kidney tumor be removed?
The most common reason a urologic surgeon performs a nephrectomy is to remove a tumor from the kidney. These tumors are usually cancerous, but they can be noncancerous (benign). Sometimes a nephrectomy is needed because of other kidney diseases.
Can a mass in the kidney be benign?
Some kidney masses are benign (not cancerous) and some are malignant (cancerous). One in four kidney masses are benign. Smaller masses are more likely to be benign. Larger masses are more likely to be cancerous.
How quickly does kidney cancer grow?
Based on the model, the average growth rate of kidney tumors in the study was 2.13 cm/year (SD 1.45 cm/year, range 0.2–6.5 cm/year). The effect of various parameters on tumor growth rate is presented in Table 2.
Are kidney tumors usually cancerous?
Kidney tumors (also called renal tumors) are growths in the kidneys that can be benign or cancerous. Most do not cause symptoms and are discovered unexpectedly when you are being diagnosed and treated for another condition.
How long can you live with untreated kidney cancer?
For example, if the 5-year relative survival rate for a specific stage of kidney cancer is 80%, it means that people who have that cancer are, on average, about 80% as likely as people who don’t have that cancer to live for at least 5 years after being diagnosed.
Is Kidney Cancer aggressive?
Collecting duct RCC is a rare and aggressive type of RCC, accounting for less than one percent of kidney cancers. The cancerous cells form irregular tubes inside the tumor. Unclassified RCC is another rare type of kidney cancer. These cells cannot be classified based on their appearance under a microscope.
Should a benign kidney tumor be removed?
A non-cancerous (benign) tumour of the kidney is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening. They are typically removed with surgery and do not usually come back (recur).
How do I know if my kidney mass is cancerous?

Does kidney cancer show up in blood tests?
Blood tests There is no blood test that can diagnose kidney cancer. But a complete blood count (CBC) and blood chemistry test can show signs in the blood that are linked with kidney cancer. For example: Too few red blood cells.
What is the first sign of kidney cancer?
Early warning signs of kidney cancer The most common sign of kidney cancer is blood in the urine (hematuria), which may make the urine look rusty or dark red. Other signs of kidney cancer may include: Low back pain or pressure on one side that doesn’t go away. A mass or lump on the side or lower back.
What happens when you have a tumor on your kidney?
Kidney cancer usually doesn’t have signs or symptoms in its early stages. In time, signs and symptoms may develop, including: Blood in your urine, which may appear pink, red or cola colored. Pain in your back or side that doesn’t go away.
Can a tumor on the kidney cause back pain?
Back pain is also less commonly a symptom of kidney cancer. About 41 percent of people with RCC report back pain. But most people don’t experience back pain until the cancer is in the later stages. The pain can range from a dull ache to a sharp stab on one side of your flank or below the ribs on your back.
How do they remove a tumor from the kidney?
Surgery to remove the tumor, the entire kidney, and surrounding tissue is called a radical nephrectomy. If nearby tissue and surrounding lymph nodes are also affected by the disease, a radical nephrectomy and lymph node dissection is performed.
