When a patient comes to me for cancer surgery, they understandably think of the operation in simple terms: the cancer is there, and surgery will take it out. But behind that straightforward idea lies a great deal of careful thought and judgement that patients rarely see. As a cancer surgeon, the goal is never simply to remove a lump — it is to remove the cancer completely and safely, in a way that gives the best possible chance of it never coming back. Let me lift the curtain a little on what that really involves, because understanding it may help you appreciate why cancer surgery is done the way it is.

Why ‘Removing the Cancer’ Is More Than It Sounds

Removing a cancer well means more than taking out what you can see. A skilled cancer surgeon thinks about the margin — a border of healthy tissue around the cancer — to make sure no cancer cells are left behind at the edges. We think about whether the cancer may have spread to nearby lymph nodes, and whether these need to be checked or removed. We consider how to remove the cancer without unnecessarily harming the function of the surrounding area. All of this planning, much of it done before the operation even begins, is aimed at one thing: removing the cancer completely while preserving as much of your normal life as possible.

The Decisions Made Before the Operation

A great deal of the most important work in cancer surgery happens before the patient ever reaches the operating theatre. We study the scans carefully to understand exactly where the cancer is and how far it extends. Crucially, the case is usually discussed by a team of specialists together — surgeons, those who treat with medicines and radiation, and others — to decide the best overall plan and the right role and timing for surgery within it. Sometimes the best result comes from giving other treatment before surgery to shrink the cancer first. These decisions, made thoughtfully and together, shape the success of everything that follows.

Balancing Complete Removal With Quality of Life

One of the constant considerations in my work is the balance between removing the cancer thoroughly and preserving your quality of life afterwards. Wherever it’s possible without compromising the cancer treatment, we use gentler, minimally invasive techniques, and we plan surgery to protect important functions. But I want to be honest about the priority: removing the cancer completely and safely always comes first. A good cancer surgeon will choose the approach that gives you the best chance against the cancer, and within that, will do everything possible to protect your normal life.

The Questions My Patients Ask Me Most

Will the surgery remove all of the cancer?

That is always the goal — to remove the cancer completely, including a margin of healthy tissue to be sure nothing is left at the edges, and to address nearby lymph nodes where needed. How completely this can be achieved depends on the individual cancer, which is why careful planning beforehand matters so much. I’ll give you an honest picture of what surgery can achieve in your case.

Can my cancer surgery be done by keyhole?

For many cancers and patients, minimally invasive surgery is possible and offers a gentler recovery. But whether it’s suitable depends on your specific situation, and the absolute priority is always removing the cancer completely and safely. If open surgery gives the better result for your cancer, that’s what I’ll recommend — the approach is chosen to serve the outcome.

Why do I need other treatments as well as surgery?

Cancer is often best treated with a combination of approaches — surgery alongside medicines or radiation — designed together by a team for the strongest result. Sometimes treatment before surgery shrinks the cancer to make removal more complete; sometimes treatment afterwards clears any remaining cells. This combined, team-planned approach gives you the best chance against the cancer.

So when you place your trust in a cancer surgeon, know that the operation is the visible part of a great deal of careful, often unseen, thought — all directed at one goal: removing the cancer completely and giving you the best possible chance of a healthy future. That is what we hold in mind at every step, even the parts you never see.
