What is kidney cancer?

Kidney cancer describes a range of tumours that develop from the cells of the kidney. Renal cell carcinoma is the most common type in adults.

Many kidney tumours grow slowly and cause no symptoms; a growing proportion are picked up incidentally on scans performed for unrelated reasons.

How it is diagnosed

Assessment usually includes cross-sectional imaging (CT or MRI) to characterise the tumour, staging scans of the chest, and blood tests to check kidney function.

A biopsy is not always necessary but may be recommended for smaller or indeterminate lesions.

Treatment options

Treatment is personalised to the size, location and features of the tumour, and to your overall health.

  • Active surveillance for small, low-risk lesions
  • Partial nephrectomy — removing the tumour while preserving the rest of the kidney
  • Radical nephrectomy — removing the whole kidney where appropriate
  • Ablation techniques for selected small tumours
  • Systemic therapy for advanced disease, coordinated with oncology
