What does a large mass on the kidney mean?
A kidney mass, or tumor, is an abnormal growth in the kidney. 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.
Are most kidney masses cancerous?
Although most kidney tumors are malignant and therefore cancerous, up to 20% are benign. Benign tumors do not spread to other parts of the body.
How is Mass on kidney treated?
Surgical removal is the most common treatment for noncancerous kidney tumors. Whether your kidney tumor is cancerous or noncancerous, you should move forward with treatment as soon as possible to avoid complications.
What percentage of kidney masses are cancerous?
About 20-30% of “suspicious” kidney tumors when removed prove to be benign! These benign growths include cysts, oncocytomas, angiomyolipomas, and mixed epithelial stromal tumors. Thus, 70-80% of these “small” kidney tumors are cancers and fortunately the majority are “well behaved” (low grade) cancers.
How do I know if my kidney mass is cancerous?
Some possible signs and symptoms of kidney cancer include:
- Blood in the urine (hematuria)
- Low back pain on one side (not caused by injury)
