Kidney cancer, also known as renal cancer, is a type of cancer that starts in the kidneys. The kidneys are a pair of bean-shaped organs located in the abdomen that play a vital role in filtering waste products from the blood and producing urine. Kidney cancer can occur in any part of the kidney, but the most common type of kidney cancer is renal cell carcinoma, which accounts for about 90% of cases.
The exact cause of kidney cancer is not known, but certain factors can increase the risk of developing this disease. These risk factors include smoking, obesity, high blood pressure, family history of kidney cancer, and long-term dialysis.
Symptoms of kidney cancer may include blood in the urine, pain in the side or lower back, a mass or lump in the side or abdomen, weight loss, fatigue, fever, and swelling in the legs or ankles. However, many people with kidney cancer do not experience any symptoms in the early stages of the disease.
Treatment for kidney cancer depends on several factors, including the stage of the cancer, the size and location of the tumor, and the patient’s overall health. Treatment options may include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. In some cases, a combination of these treatments may be used.
Regular check-ups and screenings can help detect kidney cancer early, when it is more treatable. If you have any concerns about kidney cancer or are experiencing symptoms, you should talk to your doctor.
