Malignant Kidney Tumors: Cancer

What Happens to Kidney Cancers?

• Even if your small kidney mass is a kidney cancer, it is possible that it may not grow or ever spread to other parts of the body.
• The chances of spreading depends on what specific type of kidney cancer it is.
• One type, called clear cell, is known to spread more often than other types.
• The vast majority of kidney cancers that are found as a small kidney mass will not spread or cause death if you wait to treat it.
