Renal Cell Cancer

Renal cell cancer, or kidney cancer, begins in the lining of the kidney’s tubules. These are small tubes that help filter waste and excess fluids from the blood. When cells in the kidney grow out of control, they can form a tumor, which may be benign (non-cancerous) or malignant (cancerous).

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.
7. Occupational Exposures: Certain chemicals, like asbestos and cadmium.
8. Chronic Kidney Disease: Long-term kidney problems can increase risk.
9. Genetic Syndromes: Conditions like von Hippel-Lindau disease.
10. Dialysis: Long-term dialysis can increase the risk.
11. Radiation Exposure: Previous radiation treatment in the abdominal area.
12. Hormonal Factors: Estrogen exposure may have a link.
13. Diet: High-fat diets and low fruit and vegetable intake.
14. Physical Inactivity: Sedentary lifestyle can contribute to obesity and other risk factors.
15. Acidic Urine: Higher acidity can damage the lining of the kidneys.
16. Kidney Stones: Chronic issues may increase risk.
17. Liver Disease: Increased risk with liver cirrhosis.
18. Previous Cancer: Having had other cancers increases risk.
19. Inflammatory Diseases: Conditions like lupus or other autoimmune diseases.
20. Use of Certain Medications: Long-term use of pain relievers or diuretics.
