Most people can exercise with a port or PICC line, a chemotherapy pump or a stoma. Check with your doctor and ask a nurse or exercise professional to show you how to avoid bumping it when moving.
Below are some other side effects that may need extra care.
| Weak bones | Cancer that has spread to your bones (bone metastases or bone mets) and myeloma increase your fracture risk. Some treatments, including radiation therapy and hormone therapy, can also reduce bone strength over time. Your doctor may suggest low‑impact activities like walking or swimming, and no contact sports, running or jumping. Resistance exercise can strengthen muscles to support and protect bones, but care is needed. Avoid heavy lifting, high‑impact movements, and exercises with fast, forceful or repetitive twisting or bending of the back – unless supervised by an exercise professional. If you have risk factors like bone cancer, myeloma, osteoporosis (thinning of the bones), or are having treatments that weaken bones, ask a doctor and physiotherapist or accredited exercise physiologist what exercise is safe for you. |
| Low white cell count (neutropenia) | Some cancers and treatments can weaken your immune system and cause your white blood cell count to drop. This can increase your risk of developing an infection. When your immune system is not working well (called being immunocompromised), it is important to clean any shared exercise equipment before use and avoid public spaces such as gyms, swimming pools and training venues until your white blood cell count returns to a safe level. |
| Low platelet count (thrombocytopenia) | Platelets stop bleeding in the body by forming clots. When the platelet count drops, you are at increased risk of bruising or bleeding. It is best to avoid contact sports, cycling and high-impact activities (such as jumping or boxing), as these could cause bruising or bleeding if you get knocked or fall over. |
| Skin irritation | Areas of skin affected by radiation therapy can be extremely sensitive and often uncomfortable. Choose activities and clothing to minimise fabric rubbing on affected areas. Chlorine can irritate the skin, so avoid the pool if you have a rash or your skin is red. |
| Surgical wound | You will likely need to wait for the wound to heal – so follow your surgeon’s or doctor’s advice about when it is safe to start exercise. If you have post-surgery stiffness and pain, you may need an assessment from an oncology physiotherapist or other exercise professional. They can suggest specific exercises to reduce stiffness and pain in the affected area. Pain, weakness, stiffness and reduced movement are common after surgery, but they usually improve with time. |
| Poor balance and coordination | Surgery or cancer treatment may affect balance and coordination. This can make you unsteady and lead to a fall. Make sure to exercise in good light where you can see where you’re walking. Avoid riding a bike outside, using a treadmill, or lifting free weights without a training partner. Choose exercises to improve balance and muscle strength, or exercise sitting down. |
| Peripheral neuropathy | Some chemotherapy drugs damage nerves, causing pins and needles and numbness in the hands and feet (peripheral neuropathy). This means you could injure yourself without noticing. If you can’t feel your feet, you’re more likely to lose balance or fall, so walk on even surfaces. Ask an exercise professional how to lift weights safely. Some people may find exercise machines safer to use than free weights. |
| Heart damage | Some chemotherapy drugs and other treatments can cause damage to the heart (cardiotoxicity).In this case, physical activity is still important, but you need specialised exercise advice before exercising. See Heart Health and Cancer |
