Kidney Cancer

Kidney Cancer Overview
Kidney cancer is a type of cancer that originates in the kidneys, which are two organs located near the middle of the back that filter waste from the blood. The most common type of kidney cancer is renal cell carcinoma (RCC), which starts in the small tubes of the kidney. RCC accounts for about 90% of kidney cancer cases. Kidney cancer is more common in men than in women, and the diagnosis is typically made in individuals between the ages of 50 to 70 years.
What is a Kidney Tumor?
A kidney tumor is an abnormal growth within the kidney. These tumors may be either benign (non-cancerous) or malignant (cancerous). Benign tumors generally don’t spread to other parts of the body, whereas malignant tumors can invade surrounding tissues or metastasize to other organs.
• Benign tumors: These are non-cancerous and may require minimal to no treatment.
• Malignant tumors: These are cancerous and may need aggressive treatment, such as surgery, chemotherapy, or radiation.
• Cysts: These are fluid-filled growths that are generally benign. They do not require treatment unless they cause symptoms.
Solid kidney tumors, though sometimes benign, are cancerous around 80% of the time. This means that if a solid mass is found in the kidney, there is a high chance it could be cancerous.
