What should you know about the immunotherapy revolution?

Cancer can avoid immune recognition or weaken immune responses. Some immunotherapy medicines remove signals that hold immune cells back, while other approaches help direct immune activity toward cancer cells. Treatment may be given alone or alongside surgery, chemotherapy, radiotherapy, or another medicine when that combination fits the diagnosis.

The response is not identical for everyone. The cancer type, its molecular features, previous treatment, organ function, and immune history can all affect the plan. A scan and clinical review help the team decide whether treatment is helping.

Ask which medicine is proposed, what it is intended to do, how it will be given, and how progress will be checked. Give the oncology team a complete list of medicines and supplements, and mention autoimmune disease, organ transplant, steroid use, allergies, and previous immune reactions.

Keep a record of new symptoms between appointments. Immune-related effects can involve the skin, bowel, lungs, liver, hormone glands, kidneys, or nervous system, so early reporting can change how the team manages them.

Contact your oncology team urgently for new breathlessness, chest pain, severe diarrhoea, persistent vomiting, yellowing of the skin, confusion, marked weakness, a severe rash, or a high fever. Do not wait for the next appointment if symptoms are rapidly worsening; treatment may need to be paused while the cause is assessed.

Why is this immunotherapy being considered for my cancer? Which immune-related symptoms should I report immediately? How will you distinguish treatment effects from infection or cancer symptoms?
