Does chemotherapy treat metastatic cancer?

Because it travels through the bloodstream, chemotherapy can reach cancer in more than one part of the body. Depending on the diagnosis, the goal may be to shrink cancer, delay further growth, relieve symptoms or prepare for another treatment.

Metastatic cancer keeps the identity of the organ where it began. Cancer that started in the bowel and spread to the liver is treated as bowel cancer, for example, rather than as liver cancer. That origin helps determine which chemotherapy medicines are likely to be useful.

Molecular test results, the locations and pace of spread, earlier treatment and organ function also shape the choice. Some cancers respond better to targeted therapy, hormone therapy or immunotherapy, while others are treated with chemotherapy alone or in combination.

Confirm the cancer's site of origin and ask whether tissue or blood testing changes the available medicines. Tell the team about all prescriptions, non-prescription products, allergies and past reactions, as these details can affect dosing and supportive care.

Before each visit, note new symptoms and how they affect sleep, eating, walking and daily tasks. Learn how to contact the treatment unit after hours, and check before starting supplements, vaccines or new medicines while chemotherapy is under way.

During chemotherapy, follow the treating unit's fever instructions and report possible infection promptly. Emergency assessment is appropriate for severe trouble breathing, chest pain, collapse, new confusion, uncontrolled bleeding, seizure or signs of a serious allergic reaction.

Call the oncology team without delay if repeated vomiting or diarrhoea prevents drinking, urine output drops markedly, pain becomes difficult to control, or side effects worsen rapidly. The team may need to assess dehydration, infection, blood counts or organ function.

Ask which features of your cancer support chemotherapy, what outcome the team is aiming for, when response will be reviewed, and what alternatives are available. Clarify expected side effects, precautions at home, the plan if treatment does not help, and whom to call for urgent advice.
