Tumors of the kidney are of two kinds--malignant and benign. Sarcoma is the most common of the malignant diseases to take hold of the kidney.

Symptoms

Blood in the urine. Blood sometimes is passed in clots, and often molds of the pelvis of the kidney have been passed from the bladder. Cases go almost to a fatal termination without great pain. Perhaps a decided discomfort is felt at times in the small of the back. The pain will sometimes radiate down through the course of the ureters, resembling somewhat the pain of stone in the kidney. There will be a continual loss of flesh. In some cases it will be very rapid. There is no cure. If the case can be benefited at all, it must be done by a proper dietary and proper care of the body.
