njurcancertumörer

Njurcancertumörer, also known as renal cell carcinoma (RCC), are a type of cancer that begins in the lining of the small tubules in the kidney. These tubules are responsible for filtering waste products from the blood and producing urine. RCC is the most common type of kidney cancer in adults, accounting for about 90% of cases.

There are several subtypes of kidney cancer, with clear cell renal cell carcinoma being the most prevalent. Other types include papillary renal cell carcinoma, chromophobe renal cell carcinoma, and collecting duct carcinoma. The exact cause of njurcancertumörer is not fully understood, but risk factors include smoking, obesity, high blood pressure, and certain genetic syndromes.

Symptoms of kidney cancer can be subtle and may not appear until the tumor is advanced. When symptoms do occur, they can include blood in the urine (hematuria), persistent pain in the side or back, a lump or mass in the side, fatigue, fever, and unintentional weight loss. In some cases, kidney cancer can be discovered incidentally during imaging tests performed for other medical conditions.

Diagnosis typically involves a combination of medical history, physical examination, blood and urine tests, and imaging studies such as ultrasound, CT scans, and MRI. A biopsy may be performed to confirm the diagnosis and determine the specific type of cancer.

Treatment options for njurcancertumörer depend on the stage and type of cancer, as well as the patient's overall health. These may include surgery to remove the tumor or the entire kidney (nephrectomy), targeted therapy, immunotherapy, and radiation therapy. Early detection and treatment are crucial for improving prognosis.
