Needing an unrelated operation during chemotherapy

It cannot tell you whether your operation can wait or when it is safe to have it. That depends on the operation, your medicines and your counts.

It also cannot replace a joint plan from your oncologist and surgeon. Make sure both know about each other.

Emergency operations

Appendicitis, a blocked or perforated bowel, a broken bone or a serious abscess cannot wait. Emergency surgery goes ahead with extra precautions, such as antibiotics, transfusions and close monitoring. Always tell the emergency team you are on chemotherapy, bring your treatment card, and ask them to contact your oncologist as soon as possible.

Operations that can usually wait

Many planned procedures, such as hernia repair, gallbladder removal for mild symptoms, cataract surgery, knee or hip replacement and cosmetic procedures, can usually be postponed until chemotherapy has finished and you have recovered. Your surgeon and oncologist can advise whether delaying is safe or whether symptoms mean it should happen sooner.

Wound healing

Chemotherapy slows the growth of healthy cells as well as cancer cells, which can delay wound healing. Poor nutrition, high blood sugar from steroids and smoking make this worse. Your team may wait for the wound to heal before restarting chemotherapy. Report any redness, discharge or opening of the wound promptly.

Blood clots

Cancer, chemotherapy and surgery all raise the risk of blood clots in the legs or lungs. After an operation, you may be given injections to prevent clots, compression stockings and encouragement to move early. Report pain or swelling in one leg, or sudden breathlessness, straight away.

Ports and central lines

If you have a port or central line for chemotherapy, tell the surgical and anaesthetic team. It may be used during the operation, but it needs careful handling to avoid infection. After surgery, the line should be flushed and cared for as usual. Ask who is responsible for it while you are in hospital.

Anaesthesia

General and local anaesthesia are usually safe during a chemotherapy course when planned carefully. The anaesthetist will want to know your medicines, blood results and any heart or lung effects from treatment. Some chemotherapy medicines affect the heart or lungs, which may change how anaesthesia is given.

Targeted and immune medicines

If your treatment includes targeted medicines, particularly those that block blood vessel growth, these usually need to be stopped well before surgery and restarted only after healing. Immunotherapy may also be paused. Your oncologist decides the timing; do not stop any of these medicines yourself.

Steroids and diabetes

Steroids given with chemotherapy can raise blood sugar and affect healing and infection risk. If you have diabetes, your doctors may adjust your plan around the operation. People who have taken steroids for a long time may need extra steroid cover during surgery, which your team will arrange.

Minor procedures

Smaller procedures, such as removing a skin lump, an endoscopy or dental extraction, follow the same principles on a smaller scale: check counts, time the procedure for when they have recovered, and watch for infection or bleeding. Our page on dental and minor procedures during chemotherapy explains this in more detail.

Delays to chemotherapy

Pausing chemotherapy for an operation can feel worrying. Your oncologist weighs the effect of a short delay against the risks of surgery during treatment. Sometimes the plan is adjusted to make up for the pause. Ask how the delay may affect your overall treatment and what the team recommends.

Recovery at home

Recovering from surgery while on a chemotherapy course can be tiring. Plan for help at home with meals, wound care and transport. Eat well, especially protein, move gently as advised, and keep a thermometer at home so you can check for fever if you feel unwell.

Different hospitals

If the operation happens at a different hospital from your chemotherapy, coordination becomes even more important. Ask for your oncologist's letter to be sent to the surgeon, bring recent blood results, and make sure the surgical team sends a discharge summary back to your cancer team.

What to do next

Tell your oncologist about any planned operation early, ask whether it can wait, agree a written plan for pausing and restarting chemotherapy, get a blood test close to the date, and report fever or wound problems the same day.
