Exercise and activity after kidney cancer treatment — how to start moving again, safely

Gentle movement usually starts far earlier than people expect. Short, frequent walks are encouraged from the first days after an operation, because they protect the lungs, the bowel and the circulation while you are still sore. What has to wait is loading the abdominal wall: lifting, carrying, sit-ups and heavy pushing or pulling all stress a healing incision and the muscle layers beneath it. That clearance comes from the surgical team at the centre where your operation was done, at your post-operative review, and it depends on the type of operation and how the wound has healed rather than on a fixed calendar. Ask for it explicitly rather than assuming.

For most people, yes, and staying active usually makes treatment easier to tolerate. Two things change. First, the load has to flex with how you feel that week rather than follow a fixed programme, because systemic treatment comes in cycles and energy comes in waves. Second, some side effects need adapting around: sore hands and feet on targeted therapy make walking and gym work uncomfortable, blood pressure can rise on targeted therapy, and immunotherapy can affect the thyroid, which changes stamina. All of those are monitored at your CION reviews, so tell the team what exercise you are doing and let the plan be adjusted around your results.

This is the most counter-intuitive part of survivorship, and the answer is usually yes. Cancer-related fatigue does not behave like ordinary tiredness; extra rest tends to deepen it, because losing condition makes every task cost more. Gentle, regular activity is one of the few things that reliably helps. The rule is to start below what you think you can manage, keep it regular rather than heroic, and stop while you still have something left rather than emptying the tank. If fatigue is severe, worsening or new, it needs a medical check first, because low haemoglobin, thyroid problems and other treatable causes look identical from the outside.

A mix, rather than one thing done hard. Aerobic activity such as walking, cycling or swimming once wounds are fully healed rebuilds stamina and does the most for blood pressure, weight and mood. Strengthening work matters just as much, because treatment and inactivity cost muscle, and muscle is what makes stairs, shopping and carrying a grandchild manageable again. Flexibility and balance work rounds it off, and matters more if you have been in bed a long time or have numbness in your feet after treatment. The programme that works is the unexciting one you will still be doing months from now, done on most days, at an effort where you can talk but not sing.

Usually yes, once you have surgical clearance and you rebuild rather than resume. The abdominal wall needs time before heavy lifting, and going back to your old weights in the first week is the classic way to end up with a hernia or a setback. Start light, add load slowly, and put form ahead of numbers. Having one kidney does not rule out resistance training, and the blood pressure and weight benefits of it are exactly what a solitary kidney needs. What one kidney does add is a caution about heavy contact and collision sport, where a direct blow to the flank could injure it, and that question is covered on our page about exercise and sport with one kidney.

Stop and get advice for chest pain or pressure, sudden breathlessness out of proportion to what you are doing, dizziness or fainting, a fast or irregular heartbeat, new calf pain or swelling in one leg, or sudden severe pain in the abdomen, flank or back. Also stop for anything happening at the surgical site: a bulge, a gap, fresh pain, redness or discharge. Visible blood in the urine, a fever, or a fall that struck your flank all need a call rather than a wait-and-see. None of these are common. All of them are worth a phone call the same day, and patients on follow-up at CION have a number to use for exactly this.
