Are exophytic lesions on kidneys cancerous?

Answer 1

Exactly what is an exophytic renal cyst? It is a cyst that grows from the inside-out from the organ in question, where there is a multiplying of these cysts within the kidney, which also leads to a build up of fluid. There are two kinds of cysts that can occur, one being a simple renal cyst, which is filled with liquid - with cysts with a thin wall lining itself with no problems from the first glance. The cyst only contains fluid upon observation, which is seen as either clear or yellow in color after it's been removed. It doesn't pose as a risk for future kidney cancer, so patients can breathe a sigh of relief knowing this detail.

The second kind of kidney cyst that comes into the picture is a complex renal cyst which is the opposite of the previous kind, in that the cyst is irregular when the lining is observed along with its shape as well. The features of the cysts vary depending on the type it is, for example, if it is a cyst that has fine walls or those that are coarse and thick, it would mean that it is malignant in nature, thus posing as a risk for developing into kidney cancer.
