Renal Cell Cancer

Pathophysiology

Structure of the Kidney:

• Location: The kidneys? are located on either side of the spine, just below the rib cage?.
• Components: Each kidney has three main parts: the outer cortex, the inner medulla, and the renal pelvis?.

Blood Supply:

• The kidneys receive blood through the renal arteries?, which branch off the abdominal aorta?.
• Blood is filtered in the nephrons?, the kidney’s functional units, and waste is sent to the bladder?.

Nerve Supply:

• The renal plexus supplies nerves to the kidneys, regulating functions such as blood flow and filtration.

Types of Renal Cell Cancer

1. Clear Cell Carcinoma?: The most common type, characterized by a clear appearance under a microscope.
2. Papillary Carcinoma: Usually develops in one of the kidney’s tubules and is less aggressive than clear cell carcinoma.
3. Chromophobe Carcinoma: Represents about 5% of cases; has a distinct appearance and typically a better prognosis?.
4. Collecting Duct Carcinoma: A rare type that arises from the collecting ducts in the kidney.
5. Renal Sarcoma?: A rare form that starts in the connective tissue of the kidney.

Causes of Renal Cell Cancer

While the exact cause isn’t known, several factors can increase the risk of developing RCC:

1. Smoking: Doubles the risk.
2. Obesity: Higher body weight is linked to a greater risk.
3. Hypertension?: High blood pressure may increase the risk.
4. Family History?: Genetic? factors can play a role.
5. Age: More common in people over 50.
6. Gender: Men are more likely to develop RCC than women.
