The short answer
Deciding whether to accept more anticancer treatment is a comparison of benefit against burden. Performance status, what the last treatment gave you, and time cost are the practical inputs.
Treatments for advanced cancer are often given one after another. Ask how a new one compares with what the last one gave you.
Performance status means how much of the day you are up and functioning. NCI's summary of one study lists good performance status among the strongest predictors of quality of life in advanced cancer.
A response on a scan means the tumor shrank. That is not the same as living longer or feeling better, so ask about each one separately.
Time toxicity means the days spent on appointments, travel, scans and hospital stays. It is a cost of treatment, so ask the team to estimate it.

The whole article, with every detail and caution.
This page is for people with advanced cancer, and their families, weighing whether another treatment is worth it. It covers what to ask about benefit, side effects, and time.
The question underneath the question
"Is it worth it" is not a question about cancer. It is a comparison. What is a treatment likely to give you, and what is it likely to take? The comparison needs numbers on both sides.
Ask how each new treatment compares
In advanced cancer, treatments are often given in sequence. When one stops holding the disease, another may be offered. Ask the team directly how the new one compares with what the last regimen (treatment plan) gave you. Ask what the goal is: cure, more time, or symptom control.
Performance status
Oncologists rate how much of the day you spend up and functioning. They often use the ECOG scale, which runs from 0 to 4. A score of 0 means fully active. A score of 2 means you can care for yourself but cannot work, and you are up more than half of waking hours. A score of 3 means limited self-care, and being in bed or a chair more than half of waking hours. A score of 4 means completely disabled.
NCI's summary of one study of people with advanced cancer lists good performance status among the strongest predictors of quality of life. Has your performance status changed over the last two or three months? Ask the team to state it plainly.
What a scan result does and does not tell you
A response means the tumor got smaller. That is not the same as living longer. It is not the same as feeling better either. So ask which of the three this treatment is expected to deliver. And ask for the expected benefit as a difference in months, and what the range looks like.
Time toxicity
Count the days. Infusion days. The day after. Travel, blood draws, scans, clinic waits. And any hospital stays the treatment may cause. Ask the team to estimate how many days a month this would take. Then set it against what you would otherwise do with those days.
Treatment in the last weeks
NCI's summary of end-of-life care cites a 2004 analysis. It reports that increasing numbers of patients started a new chemotherapy regimen within 30 days of death. It also notes that some patients prefer to receive chemotherapy close to death. This is not an argument against treatment. It is a reason to know where you are. And to agree in advance on what would tell you it is time to stop.
Palliative care is not the alternative to treatment
NCI says palliative care may be given at any point in cancer care, from diagnosis to the end of life. It says people may keep receiving cancer treatment while they receive it.
A 2010 randomized trial enrolled 151 people with newly diagnosed metastatic non-small cell lung cancer. Some received standard oncology care. Others received standard care with early palliative care. The early palliative care group reported higher quality of life and fewer depressive symptoms. Their median survival was longer: 11.6 months against 8.9. Fewer of them received aggressive treatment near the end of life: 33% against 54%. Accepting palliative care does not mean declining treatment.
Deciding without deciding forever
Most of these choices do not have to be settled once and for all. You can ask the team to agree in advance on the scan or the marker that will judge whether a treatment is working. You can ask what happens if it is not. That lets you try something without committing to trying everything. It also puts the stopping decision on a calendar, rather than on a bad day.

Common questions
What should I ask before agreeing to the next line of treatment?
Four things. What is the chance this shrinks or holds the cancer, as a number. If it works, for roughly how long. What it will do to how I feel and what I can do, week by week. And what the goal is: cure, more time, or symptom control. If the answer to the last is symptom control, ask whether there is a way to control the symptom without the drug.
What is performance status and why does everyone keep mentioning it?
It is a rating of how much of the day you can be up and active, usually the ECOG scale. ECOG 0 means fully active. ECOG 3 means limited self-care and being in bed or a chair more than half of waking hours. ECOG 4 means completely disabled. NCI's summary of one study lists good performance status among the strongest predictors of quality of life in advanced cancer. Ask your team for your score and how it has changed.
Is a clinical trial a reasonable option at this point?
It can be. Each trial sets its own eligibility rules, so ask early. NCI says a phase 1 trial checks whether a new treatment is safe, what its side effects are, and the highest dose people can tolerate. Ask what the trial requires in visits and biopsies.
If I decline treatment now, can I change my mind later?
Ask the team. Each option has its own rules. Ask what would still be available in a month or in three months, and what would close off. That answer often clarifies the decision more than the survival numbers do.
Does more treatment mean more time?
Sometimes. Ask for the expected difference in months, and what the range looks like. Then set that against what the treatment costs you in days spent unwell and days spent in a building.

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, and this 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 then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right 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.
