First, take a breath
A cancer diagnosis can feel unreal. Fear, anger, and stress are common. In the first days it can be hard to take in information. Give yourself permission to pause and breathe. Then ask your team how much time you have before decisions are needed.
Understand your exact diagnosis
Not all cancers are the same, and the details matter more than the word "cancer" alone. Ask your team for:
- The exact type of cancer
- Where it started
- The stage, meaning the extent of the cancer, such as how large the tumor is and whether it has spread
Ask them to write this down for you, or repeat it back in your own words to check you have it right. This information is what lets you compare treatment options later and feel more in control of decisions ahead.
Ask how much time you have
How soon treatment must start depends on the cancer. Ask your team directly whether anything is urgent and how long you have to decide. Ask them to explain why.
Build your team and support
Your care is usually led by an oncologist, a doctor who treats cancer. They work with a wider team. This often includes an oncology nurse or nurse navigator who can answer questions between visits.
Beyond the medical team, lean on family, friends, and support groups. NCI also offers help by phone at 1-800-4-CANCER (1-800-422-6237) and through its LiveHelp online chat. Many people find it easier to bring someone to appointments to listen and take notes.
Ask about a second opinion
A second opinion means another doctor reviews your diagnosis and plan. Ask your team whether one makes sense for you, and how to arrange it, before a major treatment decision.
What to ask your team
NCI advises taking a list of questions to each appointment. It is easy to forget them once you are in the room. Helpful early questions include:
- What exact type and stage of cancer do I have?
- What are my treatment options, and what is the goal of each?
- What are the expected side effects, and how are they managed?
- How much time do I have to decide, and can I get a second opinion?
- Who is my main point of contact for questions between visits?

Common questions
I was just diagnosed — what is the very first thing to do?
Take a breath. Strong feelings are common. Focus first on understanding your exact diagnosis and stage, and ask your team how much time you have before decisions are needed.
Do I have to start treatment right away?
That depends on your cancer. Ask your team how much time you have to decide, and whether anything is time-sensitive.
Should I get a second opinion?
Ask your team whether a second opinion makes sense for you, and how to arrange one. Do it before major decisions if time allows.
How can I remember everything at appointments?
NCI advises taking a list of questions to your appointments. Many people also bring a friend or family member to help listen and take notes, and ask for information in plain language or in writing.

Review details and limits
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 — Editorial review complete. This page completed Cancer Explained's editorial checks (sources, safety, plain language, duplication). It has not been reviewed by a physician or other healthcare professional.
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.
