How big is the kidney tumor?

The size of a kidney tumor varies from person to person. There is no fixed value because the tumor shape and size vary from individual to individual. Tumor size can range from 1 cm to 20 cm. In the early stages of kidney tumors, tumors are usually small, but gradually increase in size as the disease progresses. For example, the most common type of renal cell carcinoma is usually about 4 to 8cm in size, but it may increase to about 15cm in diameter when it progresses to advanced stages. As the tumor grows in size, the difficulty of treatment increases, and the tumor may compress surrounding tissues and blood vessels, causing problems such as insufficient blood supply to organs or difficulty urinating. Therefore, it is necessary to detect and treat kidney tumors as early as possible to improve the cure rate and survival rate.
