Personalised treatments designed to fight cancer while minimising side effects.
Kidney cancer, also known as renal cancer, occurs when abnormal cells in the kidney grow uncontrollably. The kidneys are bean-shaped organs that filter waste products from the blood and produce urine.
The most common type is renal cell carcinoma (RCC), which makes up about 90% of adult kidney cancers. Other less common types include transitional cell carcinoma (affecting the lining of the renal pelvis) and Wilms’ tumour, which mainly occurs in children.
According to GLOBOCAN 2020, kidney cancer ranks among the top 20 cancers in Malaysia, with more than 700 new cases and over 400 deaths each year. It is more common in men than women, and incidence increases with age.
Kidney cancer is often called a “silent disease” because it may not show symptoms in its early stages. Symptoms may develop as the tumour grows and include:
There is no routine screening programme for kidney cancer in Malaysia. The disease is often detected incidentally when patients undergo imaging (such as ultrasound, CT, or MRI) for unrelated reasons.
Those at higher risk – such as smokers, people with high blood pressure or obesity, patients on long-term dialysis, or individuals with inherited conditions like von Hippel-Lindau syndrome – may benefit from regular medical follow-up and discussions with their doctor about imaging surveillance.
Diagnosis usually involves a combination of:
To assess kidney function and look for abnormalities
Ultrasound, CT scan, or MRI to detect and stage tumours
In selected cases, to confirm the type of kidney cancer under a microscope
The exact causes are not always known, but several factors increase the risk:
Most common type, accounting for 70–80% of cases
About 10–15% of cases
Less common, usually with a better outlook
Develops in the renal pelvis and ureter lining
Mainly affects children
Tumour is less than 7 cm and limited to the kidney
Tumour is larger than 7 cm but still within the kidney
Cancer has spread to nearby lymph nodes, blood vessels, or adrenal gland
Cancer has spread (metastasised) to distant organs such as lungs, bones, or liver
Treatment depends on the stage, type of kidney cancer, overall health, and kidney function:
