The short answer
A second opinion needs glass slides, imaging on disc, the pathology report and a treatment summary. Federal law gives you access within 30 days; slides move separately and take longest.
The pathology report alone is not enough. A second-opinion pathologist needs the actual glass slides, and sometimes the paraffin block, to re-read the diagnosis.
Radiologists need the images themselves in DICOM format on a disc or shared link, not the written report. Request them from the radiology file room, not the front desk.
Under the HIPAA right of access, providers generally must give you your records within 30 days, in electronic form if held that way, cannot charge per page for electronic copies, and cannot withhold records because you owe money.
The 21st Century Cures Act information blocking rule means test results, pathology reports and imaging reports are released to your portal without delay. Download them yourself rather than waiting for a call.

The full explanation.
What a second opinion actually needs
Most people arrive at a second opinion with a folder of appointment letters and a printed pathology report. That is not the material the consulting doctor needs. A second opinion is a fresh interpretation, so it requires the raw material rather than someone else's conclusions about it.
The list is short:
- The pathology report and the glass slides — and the paraffin block if further testing may be needed.
- The imaging itself, on a disc or through an image-sharing link, including earlier scans for comparison.
- Operative notes and clinic notes from the diagnosis onward.
- A treatment summary and current medication list, with drugs, doses and dates.
The American Cancer Society's guidance on second opinions names much the same set: the pathology report, the operative report if you had surgery, the hospital discharge summary, a summary of the current treatment plan, and a full medication list.
Almost everything else in the folder is optional.
What you are entitled to
Two United States federal rules do most of the work.
The HIPAA right of access lets you inspect and obtain copies of your health records, including laboratory results and medical images. Providers generally have up to thirty days to supply them, though it is often faster. A reasonable fee may be charged, but it cannot be a per-page fee where the information is stored electronically. You can ask for the format you want, and you can direct a copy straight to someone else — the second-opinion doctor, for instance. Access cannot be denied because you owe money on a bill.
The information blocking rule, made under the 21st Century Cures Act, means electronic health information is expected to be shared rather than withheld. In practice, results reach your portal as they are finalised. If electronic records are being delayed or refused without a valid reason, claims can be filed through the federal Report Information Blocking portal.
How to request each item
Slides and blocks — start here, they are the slowest. Contact the pathology department of the hospital where the biopsy or surgery was done, not your oncologist's office. NCI's guidance on pathology reports notes that for a second opinion you will need the slides, and sometimes the paraffin block, from the pathologist or the hospital where the work was done, and that many NCI-designated cancer centres offer this review service. Ask for their outside consultation or slide release process, name where the material should go, and expect to sign a form and cover courier costs. Allow one to two weeks.
Imaging. Contact the radiology department or imaging file room, not the front desk. Ask for all studies on disc in DICOM format, including earlier scans for comparison. Many hospitals now use image-sharing platforms that transfer directly between institutions; ask whether yours does, since that is faster. Request a disc as well.
Notes and reports. Start with the portal and download what is already there: pathology report, operative report, discharge summaries, clinic notes, and any molecular or genomic report in full rather than a summary line. For anything missing, send a written request to health information management naming the specific documents and the date range. The American Cancer Society notes that copies can be requested from the doctor's office or the medical records department, and that many facilities now provide portal access.
Treatment summary. Ask your oncologist's office for one by name. It is not produced automatically, and it is the single most useful document you can hand over.
Build the one-page sheet
On one page: your name and date of birth; the exact diagnosis and stage as written in the pathology report; the date of diagnosis; biomarker and genomic results; every treatment with start and stop dates and doses; surgeries with dates; radiation site and total dose; current medications; allergies; other medical conditions; and the three questions you most want answered.
Hand it over at the start of the visit. It routinely saves the first ten or fifteen minutes of an appointment that may only be forty.
A working order of operations
- Day 1: Request slides and imaging. Download everything already in the portal.
- Day 2: Book the appointment and ask the consulting office what their intake requires.
- Day 3: Request the treatment summary and any missing notes, in writing.
- Day 7: Call to confirm the slides have shipped and the imaging has arrived. Confirmation, not assumption.
- Day 10: Write the one-page sheet.
- Before the visit: Check with the consulting office that everything is in hand. If it is not, move the appointment rather than waste it.
On timing: the American Cancer Society notes that there is usually time to consider treatment options, though some situations call for prompt decisions. Ask your own oncologist how much time you have. The legal rights described here are specific to the United States.

Common questions
Do I own my pathology slides?
In practice the laboratory that produced them retains custody, but you can direct them to be released for consultation and they are generally required to comply. Call the pathology department of the hospital where the biopsy or surgery was performed, ask for the slide release or consultation request process, and sign their form. Slides are usually loaned and returned to the originating lab. You may be asked to cover courier costs. Labs typically retain slides and blocks for around ten years.
Why do I need the images when I already have the radiology report?
A second-opinion radiologist re-reads the pictures. Re-reading changes measurements, identifies findings the first read missed, and compares against prior scans, which is often where the important information is. Reports are one radiologist's interpretation, and interpretation is exactly what a second opinion is testing. Ask for all studies plus at least one prior study for comparison.
What if the records office says it will take six weeks?
Reply in writing: "Under the HIPAA right of access, I understand you must provide these within 30 days. Please confirm the date my request will be fulfilled." Ask whether an extension has been invoked and why. If electronic records are being withheld or delayed without a valid reason, that may be information blocking under the 21st Century Cures Act, reportable through ONC's portal. In parallel, download everything already visible in your patient portal.
Can I have the records sent straight to the second-opinion doctor?
Yes. The right of access includes directing a copy to a third party you name. Many centers prefer this and will send you their own release form. Do both anyway: have a set sent to the consulting doctor and keep a complete set yourself. Records that only exist in someone else's fax queue have a way of not arriving.
Is there a fee?
There can be a reasonable, cost-based fee for copies. Electronic copies cannot be charged on a per-page basis. Slide shipping is commonly billed to you. The second-opinion pathology review itself is a billable professional service and is often covered by insurance — ask the consulting center what they charge and how they bill it.
