Munuaistuumori

Munuaistuumori refers to a growth or mass that forms within the kidney. The most common type of kidney tumor in adults is renal cell carcinoma (RCC), which originates in the lining of the tiny tubules that filter waste from the blood. Other, less common types of kidney cancers exist, as do benign (non-cancerous) kidney tumors.

Symptoms of kidney tumors can be varied and often do not appear until the tumor is advanced. When symptoms do occur, they may include blood in the urine (hematuria), persistent pain in the side or back, a palpable mass in the abdomen, fatigue, unexplained weight loss, and fever. However, many kidney tumors are discovered incidentally during imaging tests performed for other medical conditions.

Risk factors for developing kidney tumors include smoking, obesity, high blood pressure, certain genetic syndromes, and prolonged exposure to some industrial chemicals. Family history also plays a role in some cases.

Diagnosis typically involves medical history, physical examination, and imaging studies such as ultrasound, CT scans, or MRI. A biopsy may be performed to confirm the diagnosis and determine the specific type and grade of the tumor. Treatment options depend on the size, type, and stage of the tumor, as well as the patient's overall health. These can include surgery (nephrectomy), targeted therapy, immunotherapy, radiation therapy, or, in some cases, observation. Early detection and treatment generally lead to a better prognosis.
