Are exophytic lesions on kidneys cancerous?

Exophytic lesions on kidneys can be cancerous, but not all are. Exophytic lesions are those that grow outward from the surface of the kidney. Some of the conditions that can cause exophytic lesions on the kidneys include:

- Renal cell carcinoma: Renal cell carcinoma is a type of kidney cancer that often starts as an exophytic lesion. It is the most common type of kidney cancer and is typically diagnosed in people over the age of 50.

- Oncocytoma: Oncocytoma is a benign tumor that can occur in the kidney. It is typically exophytic and is usually found in people over the age of 60.

- Angiomyolipoma: Angiomyolipoma is a benign tumor that is composed of fat, muscle, and blood vessels. It is typically exophytic and is usually found in people under the age of 40.

If you have an exophytic lesion on your kidney, it is important to see your doctor for further evaluation. Your doctor will order imaging tests, such as an ultrasound, CT scan, or MRI, to determine the cause of the lesion. If the lesion is cancerous, your doctor will discuss your treatment options with you.
