Risk factors in renal cancer

The onset time of the renal cancer is generally between the 50 to 70 years of age. The frequency is 2-3 folds more in males than in females. The cause of renal cancer is not yet clearly known; however, researchers have defined some risk factors for the development of renal cancers. However, not all the individuals having these risk factors will have renal cancer, and not all the patients with renal cancer will have these factors.

Smoking: Researches show that the risk of renal cancer is 2 folds greater in smokers. This risk increases with the increasing number of cigarettes smoked per day and the elongating period of smoking. The increased risk will regress in time after quitting smoking.

Family history: A family member with renal cancer increases the risk of having renal cancer.

Diet: Diets with high calories and fried foods increase the risk.

High blood pressure: It has been shown in several studies that patients with high blood pressures have renal cancer with 3 times greater frequency.

Obesity: Being overweight can increase the renal cancer risk particularly in women.

Occupational risk factors: Renal cancer risk increases in the workers of steel industry, petroleum, cadmium and lead industry and those exposed to asbestos.

Radiation: Individuals who had received radiation therapy and those who had been exposed to radiation with other reasons have increased risk.

Dialysis: Risks of renal cysts and renal cancer is greater in patients under long-term hemodialysis program because of chronic renal insufficiency.

Genetic: Von Hippel-Lindau disease is a genetically transmitted disease, and can be accompanied by bilateral renal cancer or cancer in some other organs.
