Kidney cancer is among the top 10 most common cancers in Singapore amongst males.

Kidney cancer, also known as renal cell carcinoma (RCC), accounts for 3% of all cancers in adults.

Certain lifestyles and environmental exposures can increase the risk of having kidney cancer such as cigarette smoking, obesity and high blood pressure (hypertension). Genetic syndromes and a family history of kidney cancer is a significant risk factor.

These genetic syndromes include von-Hippel Lindau (VHL) syndrome and tuberous sclerosis among others.

The classic triad of pain, blood in the urine (haematuria) and an abdominal mass only occurs in less than 10% of patients and most kidney cancers are detected incidentally in this day and age.

Surgical treatment has good results when the cancer is detected early while new medications are being developed to treat disease in advanced disease.
