What should you know about secondary prevention of cancer?

Follow-up can involve examinations, blood tests or scans at intervals chosen by the oncology team. The purpose is to notice recurrence, a new cancer or a treatment-related problem early enough to discuss options. Screening for people without symptoms is different from follow-up after cancer and follows its own plan.

Prevention also includes checking symptoms rather than waiting for the next appointment, taking prescribed treatment as directed, avoiding tobacco, protecting skin from excess sun and keeping vaccinations and other health care up to date when appropriate. These steps support health but cannot remove every risk.

Keep a written survivorship or follow-up plan with the cancer type, treatments, expected effects, warning symptoms and contact details. Tell the team about a new lump, persistent pain, unexplained bleeding, lasting cough, bowel change or weight change. Ask which symptoms need a same-day call and which can wait for routine review.

If disease has returned or spread, options may include systemic treatment such as chemotherapy, symptom-focused palliative care and discussion of a clinical trial. A second opinion can help clarify choices when the diagnosis or treatment plan feels complex.

Get urgent help for severe breathlessness, chest pain, sudden weakness, confusion, uncontrolled bleeding, a high fever during treatment, or inability to keep fluids down. Contact the oncology team promptly for a new symptom that is worsening or persistent rather than waiting for a scheduled visit.

What is my follow-up schedule and what is each test checking? Which symptoms should trigger an urgent call? What can I do to reduce treatment-related harm? How will we assess recurrence? Would a second opinion or clinical trial be relevant if the cancer changes?
