Renal Cell Carcinoma (RCC) is a type of kidney cancer that originates in the lining of the renal tubules. It is the most common form of kidney cancer in adults, accounting for about 90% of cases. RCC can occur in one or both kidneys and may spread to other parts of the body if not detected early. Symptoms of RCC may include blood in the urine, persistent back pain, unexplained weight loss, and fatigue. Risk factors include smoking, obesity, high blood pressure, and certain genetic conditions. Early diagnosis and treatment are crucial for improving outcomes in patients with RCC.
