Surgical Oncology
Overview
Surgery is still a main cancer treatment option used for diagnosis, staging and even symptom relief.
As a cancer management method, it involves the physical removal of malignant tumours from the body.
For some tumours, cancer surgery may offer the best chance of cure, especially if the cancer is localised. In other cases, it may be used as a primary treatment in conjunction with other prescribed treatments.

What cases of colon cancer can be treated with a transanal endoscopic surgery?
Transanal endoscopic surgery is a method of keyhole surgery without creating a scar by using the anus as a natural orifice access. A camera and 2 small keyhole instruments can be inserted to allow the surgery to be performed. It is used to remove benign growths in the rectum that are deeper than the reach of the surgeon's finger. This is indicated for benign tumours between 7-12cm from the anus.
What should I do if my cancer antigen 125 (CA125) tumour marker are elevated?
The CA 125 is a protein found in the blood and is often used as a tumour marker for ovarian cancer. The normal value is usually between 0 to 35 units/ml. CA 125 can be elevated in both benign and malignant conditions, so having a raised CA 125 does not mean you have cancer. In about 1% of healthy women, it is slightly elevated in the absence of disease.
