Does chemotherapy treat breast cancer?

It may be given before surgery to shrink a tumour, after surgery to destroy cancer cells that could remain, or when breast cancer has spread beyond the breast. Some breast cancers are treated mainly with other medicines, surgery or radiotherapy instead.

The oncology team considers the tumour's hormone-receptor and HER2 status, its grade and extent, lymph-node involvement, previous treatment and your general health. These details help show whether chemotherapy is likely to add useful cancer control.

Chemotherapy travels through the bloodstream, so it can reach cancer cells outside the breast as well as the main tumour. It is often delivered in treatment cycles, with recovery time between doses. The exact medicines and schedule are tailored to the clinical situation.

Ask what the treatment is intended to achieve, which medicines are planned and how response will be checked. Give the team a complete list of prescriptions, supplements and allergies because some products can interfere with treatment.

Before each cycle, the team may assess symptoms and blood results. Report side effects early rather than waiting for the next appointment. Practical planning for transport, meals, work and help at home can make treatment days and recovery periods easier to manage.

Use the oncology team's urgent contact instructions if you develop a fever, chills, sudden breathlessness, chest pain, confusion, uncontrolled vomiting or diarrhoea, unusual bleeding, or signs of a serious allergic reaction. Chemotherapy can lower infection-fighting blood cells, so feeling acutely unwell needs prompt assessment even when a temperature reading seems normal.

You might ask why chemotherapy is being recommended for this breast cancer, what alternatives are reasonable, whether treatment comes before or after surgery, which side effects need an urgent call, and how the plan may affect fertility, work or other medicines.
