What Is Cancer Surgery?
Cancer surgery involves physically removing a tumour from the body. It can be performed as a standalone procedure or combined with other treatment methods such as chemotherapy, radiation, immunotherapy, or targeted therapy. The extent and type of surgery depend on several factors including the type of cancer, its stage, and where it is located.
Why Surgery Is Often The First Line Of Defence
There are several reasons why surgery is frequently the first step in a patient’s cancer treatment journey:
Curative Potential
Surgery can offer the highest chance of curing the cancer, particularly when it is detected early and remains localised. By completely removing the tumour, it is sometimes possible to eradicate the disease before it spreads.
Immediate Tumour Removal
Unlike other treatments that act over weeks or months, surgery can immediately remove most or all of the cancerous tissue. This can relieve pressure on nearby organs and significantly reduce the tumour burden.
Precise Diagnosis And Staging
Surgical procedures enable doctors to observe the cancer directly and collect tissue samples. This helps in accurately staging the disease, assessing lymph node involvement, and planning further treatment.
Facilitates Additional Treatments
Surgery often forms the foundation of combination therapy. For instance, after a tumour is surgically removed, chemotherapy or radiation may be used to destroy any remaining cancer cells and reduce the risk of recurrence.
Symptom Relief In Advanced Cancers
Even when a cure isn’t possible, surgery can still provide significant benefits. It can relieve pain, control bleeding, or remove obstructions, thereby improving the patient’s quality of life.

When Surgery May Be Preferable Over Chemotherapy
Chemotherapy is another major form of cancer treatment, but it may not always be suitable as the initial option. For example, in early-stage colon cancer, using chemotherapy first may delay definitive tumour removal. This can allow the cancer to grow or spread while systemic drugs are working slowly and may not fully penetrate the primary tumour. In contrast, surgical resection of the colon tumour can immediately remove the cancerous mass and eliminate the source of spread, offering a potentially curative solution without waiting for the effects of chemotherapy.
Furthermore, chemotherapy often comes with side effects such as nausea, fatigue, and immunosuppression, which can reduce a patient’s strength and delay recovery—especially problematic if surgery becomes necessary later.
