How do I ask my doctor for a second opinion?

It's fine to ask directly and simply. The National Cancer Institute's own suggested questions include asking your doctor whether they will help you find someone for another opinion on the best treatment plan. Most doctors are used to this request, and many will actively help you arrange it, including recommending specialists or centers.

A straightforward way to bring it up is to say something like, "Would you support me getting a second opinion?" or "Can you help me find a specialist to review my case?" You don't need to justify the request or worry that it will damage your relationship with your current doctor — seeking a second opinion is a routine, expected part of cancer care, not a sign of distrust.

Once you've raised it, practical questions follow: what records, slides, or scans you'll need to bring, whether getting a second opinion will delay your treatment, and whether your insurance covers it. You can also ask whether you want a second opinion specifically on the pathology diagnosis, on the treatment plan, or both, since these can be sought separately.

Many institutions, including NCI-designated cancer centers, regularly provide second-opinion reviews and can walk you through their specific process.
