For a slow-growing lymphoma that is not causing problems, treating straight away has not been shown to help people live longer, so the usual plan is regular checks and treatment later. It is the hardest thing in lymphoma to be told, and the evidence behind it is good.
**What the choice is.** Most follicular lymphoma is advanced by the time it is found, because it grows slowly and causes few symptoms. For someone with no symptoms, no organ problem and no fast-growing nodes, the options are to start treatment now or to be monitored and treated when the disease begins to cause trouble. Lymphoma Action calls the second one active monitoring, and lists the diseases it is used for: follicular lymphoma except grade 3B, the marginal zone lymphomas, Waldenstrom macroglobulinaemia, chronic lymphocytic leukaemia and small lymphocytic lymphoma, some mantle cell lymphoma, and nodular lymphocyte predominant Hodgkin lymphoma.
**What is known about waiting.** The randomised evidence is a British-led trial of 379 people with asymptomatic, non-bulky, advanced follicular lymphoma, reported by Ardeshna and colleagues in 2014. People given rituximab waited longer before needing chemotherapy or radiotherapy than people watched, and overall survival did not differ between the groups. In other words, starting treatment earlier bought time to the next treatment and did not add years of life. Lymphoma Action lists the gains from waiting plainly: you avoid the side effects and the late effects for as long as possible, the full range of treatment is still open to you, your appointments are occasional rather than constant, and new treatments arrive while you wait.
**What is known about the waiting itself.** Lymphoma Action says monitoring means one to four check-ups a year, with a conversation about symptoms, an examination of the neck, armpits, groin and abdomen, and blood tests; a scan is not usually done unless the team suspects the lymphoma is growing, in order to avoid unnecessary radiation. Treatment is usually suggested when the marrow is affected and blood counts are falling, when an organ is affected, when nodes or the spleen grow quickly or appear in new places, when fever, night sweats and weight loss appear, or when symptoms become difficult to live with. Some people need treatment soon; some wait many years; some never need it.
**What nobody can tell you.** How long your own wait will be. Lymphoma Action says this varies a great deal and is hard to predict, and that follicular lymphoma transforms into a faster-growing lymphoma in 2 to 3 people in every 100 each year, which is why a change in symptoms is a reason to ring rather than to wait for the next appointment.
**The part that is not medical.** A person on active monitoring quoted on the Lymphoma Action page puts the difficulty exactly: "Active monitoring is counter-intuitive: 'I have cancer, but it's not being treated.' There is no physical battle, but there is a psychological challenge." The charity says many people find it helps to think of the lymphoma as a long-term condition to manage, that family and friends often find the approach harder to understand than the patient does, and that anxiety in the weeks before a check-up is common. Its helpline is free on 0808 808 5555 and is open to relatives as well as patients.
