Cancer chemotherapy side effects

Chemotherapy targets rapidly dividing cells. It can also affect healthy cells in the bone marrow, digestive tract, hair roots, skin, and reproductive organs. Your oncology team will explain which effects fit your regimen and how they will monitor you.

Possible effects include tiredness, nausea, appetite changes, mouth soreness, altered taste, constipation, diarrhoea, hair loss, skin or nail changes, and tingling or numbness. Lower blood-cell counts can raise the chance of infection, bruising, bleeding, breathlessness, or fatigue.

Not everyone develops every effect. Timing also differs: some problems begin around an infusion, while others emerge between treatment cycles or build gradually. Side-effect severity does not show whether chemotherapy is working, so never judge treatment response from how unwell or well you feel.

Take prescribed anti-sickness and other supportive medicines exactly as directed, including doses scheduled before symptoms begin. Sip fluids regularly, choose foods you can tolerate, use gentle mouth care, pace activity, and rest when needed. Check before taking supplements, herbal remedies, or non-prescription medicines because they may interact with treatment.

Keep a brief record of symptoms, temperature readings, bowel changes, food and fluid intake, and any missed medicines. Contact your treatment team early if an effect is worsening or stopping you from eating, drinking, sleeping, or completing usual self-care; adjustments and supportive treatments may help.

Follow the emergency instructions and temperature threshold supplied by your oncology unit. Call the unit immediately for fever, chills, sudden illness, breathing difficulty, confusion, uncontrolled vomiting or diarrhoea, inability to keep fluids down, unusual bleeding, black stools, a severe rash, chest pain, or swelling of the face or throat.

Do not wait for a planned appointment if infection is possible during chemotherapy. If you cannot reach the oncology unit, seek emergency care and tell staff that you are receiving chemotherapy, the medicine name if known, and when the latest dose was given.

Ask which effects are expected with your specific medicines, which phone number operates outside clinic hours, what temperature should trigger a call, and which vaccinations or dental procedures need coordination. It is also useful to discuss fertility, work, driving, exercise, and medicines you already take before the first cycle.
