What does chemotherapy treat?

The medicines may be given before surgery to shrink a tumour, after local treatment to address cells that may remain, or when cancer has spread. The choice depends on the cancer type, its location, its extent, and your general health. Chemotherapy can be one medicine or a combination, delivered in cycles with planned recovery time.

Your oncology team will explain the intended goal, schedule, route of treatment, and possible effects before starting. Tell them about other medicines, supplements, infections, and any pregnancy possibility. Keep a written record of symptoms and temperature if advised. Treatment plans may be adjusted when blood tests, symptoms, or scans show that a different approach is needed.

Contact your cancer team promptly for fever, chills, new breathlessness, persistent vomiting, severe diarrhoea, unusual bleeding, or pain that is not controlled by the agreed plan. A treatment centre may give you a direct number and a specific temperature threshold; follow that personalised instruction rather than waiting for the next appointment.

Ask what the treatment is intended to achieve, how you will receive it, which side effects need same-day advice, and whether other treatments will be combined with it. Ask how the team will check whether it is helping.
