Guide To The Major Types Of Kidney Cancer And Tumors

Sarcoma

Renal sarcoma is a type of kidney cancer that begins in the mesenchymal cells of the kidney. These are the cells that form connective tissues. Several types of sarcomas can develop in the kidney. However, the most common are liposarcomas, leiomyosarcomas, fibrosarcoma, osteosarcoma, angiosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma. The perisinuous space and the organ capsule are the most prevalent origination point of renal sarcomas.

Since these types of tumors have developed from connective tissue cells, they have a greater ability to cross fascial anatomical boundaries to other organs. These renal tumors grow rapidly and often spread to the lymph nodes, lungs, or liver. Hematuria, flank pain, and a palpable flank mass are common symptoms of renal sarcoma. Urine tests, blood tests, angiography, computerized tomography scans, and kidney tissue biopsy are used to make a renal sarcoma diagnosis. As this type of kidney cancer is more aggressive than others, most patients will need surgery, chemotherapy, and radiation therapy at some point.
