The short answer
Declining the end-of-treatment bell is a considered choice for many people, not ingratitude. The ritual is actively debated in oncology and several centers have redesigned it.
The bell ritual dates from a single US cancer center in 1996 and spread widely; it was never a clinical intervention and has never been shown to help.
The most commonly given reason for declining is the audience: the ceremony happens in a room where other people are not finishing, and some of them will not.
For people on maintenance or endocrine therapy, or living with metastatic disease, the bell marks an ending that does not exist in their case.
Treatment sometimes stops because it was not working, or because a person chose to stop. There is nothing to celebrate in those endings and the ritual has no place for them.

The full explanation.
A Custom, Not a Treatment
The bell in the infusion suite or radiotherapy department is a recent invention. The practice is generally traced to a single US cancer center in 1996, and it spread from there to hospitals around the world. It was never designed as a clinical intervention. It has no evidence base behind it. It became standard largely because it looked good and felt right to the people who introduced it.
For plenty of people it does work. They ring it, their family cheers, and something that needed marking gets marked. For plenty of others it is the last thing they want, and they find there is no obvious way to say so.
The Reasons People Decline
The audience. This is the one people mention most. The bell is rung in a room where other people are mid-cycle. Some of them are not going to finish, because their treatment is continuous or because their disease will not stop. Oncology nursing literature describes patients with metastatic or progressive disease reporting anger, resentment and low mood when they hear the cheering. They know this particular milestone is not available to them. Some units in the UK have removed bells for exactly this reason. Being congratulated in front of people for whom the same ending does not exist is not a small thing to ask of someone.
The ending is not an ending. Chemotherapy finishes, and endocrine therapy runs for five or ten years. Immunotherapy continues. Maintenance treatment has no completion date. Surveillance scanning goes on for years. Ringing a bell announces completion. When what has completed is one phase of something ongoing, that misrepresents your situation to everyone in the room, including yourself.
It stopped for the wrong reason. Treatment ends when it is not working. It ends when toxicity becomes unmanageable. It ends when someone decides they have had enough. There is nothing to celebrate in those endings, and a ceremony built around triumph has no shape that fits them.
The feeling is not there. People often reach the last session exhausted. They are frightened about losing the safety of regular monitoring, and grieving things treatment cost them. A public celebration in that state is a performance, and performing gratitude on demand is draining.
Superstition. Some people simply do not want to declare anything finished. That is not irrational. It is a reluctance to make a claim the scans have not yet confirmed.
Privacy. Some people do not want a public moment of any kind, on any subject.
The Debate Inside Oncology
This is not only a patient complaint. It is being discussed seriously in the professional literature and at nursing conferences. The core criticism is about the implicit message. A ritual celebrating completion, performed in a shared space, suggests that completion is the definition of success. That quietly places everyone on lifelong treatment on the wrong side of the line.
The responses have been practical rather than abolitionist. Penn Medicine redefined its bell so it marks any milestone: a good scan, the end of a phase, a hard day survived. Signage explains the wider meaning, so that patients on continuous treatment can use it too. Duke Cancer Institute moved bells outdoors into garden spaces. Ringing there becomes a private choice, rather than a public event staged for an unwilling audience. Other centers offer certificates, a quiet word with the team, or nothing at all.
Declining, and Marking It Another Way
Saying no is easier in advance than on the day. "I would rather not ring it" is a complete sentence, and staff hear it often enough not to be surprised. You can also ask whether you can ring it at a quiet time, or somewhere else. That is reasonable, and frequently possible.
If you do want to mark the end, private markers tend to fit better anyway. A meal with the two people who drove you to appointments. A walk you could not have managed six months ago. A note to the nurse who got the cannula in first time. A day off doing nothing at all.
And if you want the bell, the cheering and the photograph, take it. The point is that it is optional, and that neither choice says anything about you.

Common questions
Where did the bell come from?
The practice is generally traced to a US cancer center in 1996 and spread from there to hospitals worldwide. It was adopted informally rather than introduced as a clinical intervention, and there is no evidence base showing it improves outcomes or wellbeing.
Is it rude to decline?
No. Staff see people decline regularly. A short sentence is enough — you would rather not, or you would rather mark it privately. No explanation is required, and it is easier to say in advance than on the day.
Why does the bell upset other patients?
Because it is rung in front of them. Oncology nursing literature describes patients with metastatic or progressive disease reporting anger, resentment and low mood on hearing the cheers, knowing that treatment completion is not something available to them. Some units have removed or relocated bells for this reason.
What if my treatment is ending badly?
That is a real and common situation the ritual does not accommodate. Treatment stops for many reasons — it was not working, toxicity became unmanageable, or someone chose to stop. There is nothing celebratory in those endings, and a ceremony designed around triumph is the wrong shape for them.
Are there alternatives?
Yes, and centers are actively developing them. Some have moved bells to gardens or quiet outdoor spaces so people can choose to ring them without an audience. Others have redefined the bell to mark any milestone — a good scan, the end of a phase, a difficult day got through — so that it is available to everyone rather than only to people finishing. Private markers work too.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
