A small kidney tumor is a growth in the kidney that measures 4 cm (approximately 1.6 inches) or smaller, roughly the size of 2 nickels. The kidneys are 2 bean-shaped organs roughly the size of a fist. The kidneys filter the blood and remove toxins and extra fluid from the body by making urine.
How can you tell if a kidney cyst is cancerous?
The way we may distinguish the benign from cancerous (malignant) cysts is by way of imaging such as Kidney Ultrasound, CT scan or MRI. Rarely, however, there are cysts that are actually cancerous. The way we may distinguish the benign from cancerous cysts is by way of imaging such as Kidney Ultrasound, CT scan or MRI.
How do you treat a lesion on the kidney?

How fast do kidney tumors grow?

Is a 10 cm kidney cyst large?
A woman should have kidneys that are at least 10 centimeters in length. A complex cyst means that the fluid filled cyst is not round, may have echos within the cyst, and may need careful followup to make sure it is benign.

A bone lesion is considered a bone tumor if the abnormal area has cells that divide and multiply at higher-than-normal rates to create a mass in the bone. The term “tumor” does not indicate whether an abnormal growth is malignant (cancerous) or benign, as both benign and malignant lesions can form tumors in the bone.
