Angiomyolipoma: These are a type of BENIGN renal neoplasm. So yes it is a cancer but it is a benign form. These are the most common benign solid kidney tumor. Most of the cases are random events typically in females and around 40 years old. The other 20% of cases have an association with certain neurological disorders. They may cause flank pain, hematuria and can spontaneously rupture causing bleeding.
