Physiotherapy after cancer treatment

After treatment ends, many patients feel stranded. The intensive medical team steps back to surveillance mode, but the physical effects persist. Cancer-related fatigue affects 70 to 100% of patients during treatment and 30 to 40% for months or years afterwards.

Surgical scars restrict movement. Chemotherapy weakens muscles and can damage peripheral nerves. Radiation causes tissue tightness in the treated area. Lymphedema (swelling from lymph node removal or radiation) needs active, ongoing management.

Most oncologists focus on tumour monitoring and may not discuss physical rehabilitation. This is not neglect. It is a gap in the system, similar to how orthopaedic surgeons often skip physiotherapy referrals. The good news is that physiotherapy directly addresses these consequences.

Lymphedema is persistent swelling that develops when lymph nodes are removed or damaged during cancer treatment. It is most common after breast cancer surgery (affecting 20 to 30% of patients) but also occurs after gynaecological cancers, head and neck cancers, and any surgery involving lymph node removal.

Without management, lymphedema can worsen progressively. The physiotherapy approach is called complete decongestive therapy (CDT), which combines manual lymphatic drainage (a gentle massage technique that redirects fluid), compression garments, specific exercises, and skin care.

Your physiotherapist also teaches self-management: self-massage techniques, how to use and care for compression garments, exercise modifications to prevent flare-ups, and warning signs to watch for. Early intervention, even preventive physiotherapy before swelling starts, leads to better outcomes.

After an initial in-person assessment, follow-up exercise guidance and monitoring can continue effectively online.

This is counterintuitive: rest does not fix cancer-related fatigue, but exercise does. Multiple studies confirm that graded exercise is the single most effective treatment for cancer-related fatigue, more effective than medication or rest.

The cycle works like this: you feel exhausted, so you rest more and move less. Your muscles weaken and cardiovascular fitness drops. Everything becomes more tiring. Resting more continues the decline.

A physiotherapist breaks this cycle with carefully graded exercise, starting from wherever you are, even if that means five minutes of gentle movement. Aerobic exercise like walking and resistance training both help. The programme adjusts based on your energy levels and treatment cycles.

Progress is often noticeable within four to six weeks. Many patients are surprised at how much better they feel when they start moving more, even though it seems illogical when you are exhausted.

After surgery: restricted shoulder movement is common after breast or axillary surgery. Abdominal weakness follows abdominal procedures. A physiotherapist helps restore range of motion and rebuild strength gradually.

Chemotherapy-induced peripheral neuropathy causes numbness, tingling, and balance problems in the hands and feet, similar to diabetic neuropathy. Balance training and sensory exercises help manage this.

Radiation fibrosis causes tissue tightness in the treated area, which can progress months or years after treatment. Stretching and mobility exercises help maintain tissue flexibility.

Many cancer treatments also accelerate bone loss through hormone therapy, steroids, or premature menopause. Weight-bearing exercise helps maintain bone density and reduce fracture risk.

Ideally, physiotherapy starts before treatment begins. Pre-treatment exercise (prehabilitation) builds physical reserves that help you tolerate treatment better. During treatment, gentle exercise is maintained as tolerated. After treatment, progressive rehabilitation begins.

But it is never too late. Even years after treatment, persistent fatigue, stiffness, or lymphedema respond to structured physiotherapy. Many patients assume these are permanent consequences of treatment when they are actually treatable.

Your physiotherapist coordinates with your oncology team. Most patients can safely exercise during and after treatment. The programme accounts for blood counts, immune status, bone health, and any surgical precautions.

Online physiotherapy works well for exercise guidance, fatigue management, and lymphedema self-care education. Initial lymphedema assessment and manual lymphatic drainage typically benefit from an in-person visit, with follow-up continuing online.
