Kidney cancer begins in the tissues of the kidneys, the two bean-shaped organs located on either side of the spine. The most common type is renal cell carcinoma, which accounts for about 90% of adult kidney cancers. While some tumors are slow growing, others can be aggressive and require early diagnosis for the best outcome. ## Symptoms of Kidney Cancer In the early stages, kidney cancer may not cause noticeable symptoms. As the disease progresses, you may experience: - Blood in the urine (hematuria) - Persistent pain in the side or back - Unexplained weight loss - Fatigue - A lump or mass in the abdomen or side - Fever not caused by an infection - Swelling in the legs or ankles Because many of these symptoms overlap with other health issues, it's not important to speak with your provider if you notice any changes. ## What Are the Risk Factors? Certain factors can increase your risk of developing kidney cancer, including: - Smoking - Obesity - High blood pressure - Family history of kidney cancer - Chronic kidney disease or long-term dialysis - [Exposure to harmful substances,](https://www.cancer.org/cancer/types/kidney-cancer/causes-risks-prevention/risk-factors.html) such as a trichloroethylene or cadmium in the workplace Men and people over 60 are also at higher risk. ## How is Kidney Cancer Diagnosed? Many cases of kidney cancer are discovered during imaging for unrelated issues. Diagnosis may include: - Blood and urine tests to assess kidney function - Imaging studies such as ultrasound, CT scan, or MRI - Biopsy, if needed to confirm diagnosis ## Why Early Detection Matters Finding kidney cancer early, before it spreads beyond the kidney, significantly improves treatment success. According to the American Cancer Society, the 5-year relative survival rate for localized kidney cancer is 93%. Routine checkups and talking with your doctor about symptoms or family history can lead to early detection and better outcomes. ## Treatment Options Depending on the stage and type, treatment may include: - Surgery to remove part of all the kidney - Ablation or embolization therapies - Immunotherapy - Targeted therapy - Active surveillance for small, slow-growing tumors Your care team will guide you through the best approach based on your individual needs.
