Kidney cancer occurs when abnormal cells in the kidneys begin to grow uncontrollably and form a tumor. The kidneys are two bean-shaped organs located on either side of the spine that filter waste and excess fluids from the blood to produce urine. The most common type is Renal Cell Carcinoma, which begins in the lining of the kidney’s small tubes. Kidney cancer may not show symptoms in early stages, but as it progresses it can cause blood in urine, back pain, fatigue, weight loss, and swelling around the kidneys. Early detection and proper treatment can significantly improve outcomes.
