Understanding Kidney Cancer in Singapore

Renal cell carcinoma represents a significant proportion of kidney cancers in adults. This type originates in the lining of the proximal convoluted tubule, the kidney’s filtering component. RCC has several subtypes, with clear cell RCC being common. Other subtypes include papillary RCC and chromophobe RCC, each with distinct cellular characteristics and treatment responses.

Also called urothelial carcinoma, this type begins in the renal pelvis, where urine collects before moving to the bladder. This cancer type behaves differently from RCC and often requires distinct treatment approaches, as it’s more similar to bladder cancer in its characteristics and response to therapy.

This kidney cancer primarily affects children. Whilst uncommon in adults, Wilms’ tumour represents a portion of childhood cancers. It may have a positive prognosis when detected early and treated appropriately with combination therapy. *Individual results and timelines may vary.*

A form of kidney cancer, renal sarcoma develops in the kidney’s connective tissue or blood vessels. This type is uncommon and may require treatment due to its characteristics. This treatment is administered as part of a comprehensive plan supervised by a healthcare professional.

The exact cause of kidney cancer remains unclear in most cases. Kidney cancer may develop when kidney cells undergo DNA mutations that can cause them to grow and divide rapidly. These abnormal cells may accumulate to form a tumour, which can grow beyond the kidney and spread to other organs. A single cause cannot be pinpointed, but multiple factors may contribute to these cellular changes.

• Smoking: Cigarette smoking may increase the risk of developing kidney cancer
• Obesity: Excess body weight may alter hormone levels and kidney function, potentially increasing cancer risk
• High blood pressure: Hypertension may increase kidney cancer risk
• Family history: Having a first-degree relative with kidney cancer may elevate risk
• Chronic kidney disease: Long-term kidney dysfunction, especially requiring dialysis, may increase cancer risk
• Genetic conditions: Inherited syndromes like von Hippel-Lindau disease, hereditary papillary renal cell carcinoma, and Birt-Hogg-Dubé syndrome
• Occupational exposure: Regular contact with certain chemicals like cadmium, organic solvents, and asbestos
• Age: Risk may increase with age, with cases commonly diagnosed in older adults
• Gender: Men may have increased risk compared to women
• Previous radiation therapy: Prior radiation treatment to the abdomen or pelvis may increase risk

Individual risk factors and their impact may vary.

Seek immediate medical attention if you notice blood in your urine, even if it occurs only once. This symptom requires professional evaluation to determine its cause. Persistent pain in your side, back, or abdomen that doesn’t respond to usual pain relief also warrants medical assessment.

Schedule a consultation if you experience unexplained weight loss, persistent fatigue, or recurring fevers without apparent infection. These symptoms may indicate various conditions and require proper investigation. If you have risk factors such as a family history combined with smoking or obesity, consider discussing screening options with a Singapore urologist.

During your first consultation, the urologist will conduct a comprehensive medical history review, physical examination, and order appropriate diagnostic tests. The appointment involves discussing your symptoms, risk factors, and any concerns you may have. Blood and urine tests are usually performed initially, followed by imaging studies if indicated. This systematic approach aims to support accurate diagnosis whilst addressing your immediate concerns and questions about the diagnostic process.

Complete blood count (CBC) checks for anaemia and other blood abnormalities that may be associated with kidney conditions. Comprehensive metabolic panel assesses kidney function through creatinine and blood urea nitrogen levels. Urinalysis examines urine for blood, abnormal cells, and proteins that might indicate kidney problems. These tests provide baseline information about overall health and kidney function.

CT (computed tomography) scans with contrast provide detailed cross-sectional images of the kidneys, helping identify masses, their size, and extent. MRI (magnetic resonance imaging) offers detailed soft tissue imaging, which can be useful for assessing potential invasion into surrounding structures or blood vessels. Ultrasound serves as an initial screening tool, distinguishing between solid masses and fluid-filled cysts.

Biopsy may be performed when imaging results are inconclusive. The procedure involves inserting a thin needle through the skin to obtain tissue samples from the kidney mass. CT or ultrasound guidance aims to ensure accurate needle placement. Results may become available, providing cellular diagnosis. Individual results and timelines may vary.

nce kidney cancer is confirmed, additional tests may be performed to determine the cancer’s stage. Chest CT scans can check for lung involvement. Bone scans may be ordered if bone symptoms are present. PET scans can help identify distant spread in select cases. These staging investigations help guide treatment planning discussions.

While kidney cancer cannot be completely prevented, several strategies may help reduce risk. Smoking cessation represents an important modifiable risk factor, with risk potentially decreasing after quitting.

Maintaining healthy body weight through balanced nutrition and regular physical activity may help reduce kidney cancer risk. Regular physical activity and a diet rich in fruits and vegetables, particularly those high in antioxidants, may provide protective benefits. Limiting processed meats and excessive salt intake may help support kidney health over time.

Managing blood pressure through lifestyle modifications and appropriate medical treatment when necessary may help protect kidney health. Regular monitoring and control of diabetes may also support kidney health. For those with occupational chemical exposure, following safety protocols including proper protective equipment use may help minimise risk. Individuals with genetic predisposition or family history should discuss screening protocols with their urologist to enable early detection.
