How to Organize Cancer Records for a Second Opinion

What a second opinion actually needs: slides, imaging on disc, notes, a treatment summary. How to request each, how long it takes, and your access rights.

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 must act on your request within 30 days, in the form you ask for if it can be readily produced, and may charge only a reasonable, cost-based fee.

  • The 21st Century Cures Act information blocking rule means test results, pathology reports and imaging reports are released to your portal without delay. Check your portal and download what is there.

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 needs the raw material, not someone else's conclusions about it.

The list is short:

  1. The pathology report and the glass slides — and the paraffin block if further testing may be needed.
  2. The imaging itself, on a disc or through an image-sharing link, including earlier scans for comparison.
  3. Operative notes and clinic notes from the diagnosis onward.
  4. 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. It lists 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.

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 must act on a request within 30 days, with one possible 30-day extension. A reasonable, cost-based fee may be charged. You can ask for the format you want. You can also direct a copy straight to someone else, such as the second-opinion doctor.

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, many results reach your portal quickly. If electronic records are being delayed or refused without a valid reason, you can file a claim 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. Do not go to your oncologist's office for this. NCI's guidance on pathology reports notes that for a second opinion you will need the slides. Sometimes you also need the paraffin block (the wax-preserved tissue sample). These come from the pathologist or the hospital where the work was done. It also notes that many NCI-designated cancer centers offer this review service. Ask for their outside consultation or slide release process. Name where the material should go. Expect to sign a form, and ask about costs.

Imaging. Contact the radiology department or imaging file room, not the front desk. Ask for all studies on disc in DICOM format, which is the standard file format for medical images. Include 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 patient portal and download what is already there. That includes the 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. Name 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

Put all of this 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 can save time at the start of the visit.

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. Ask the lab about any costs and return rules.

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?

A reasonable, cost-based fee is allowed, limited to labor for copying, supplies for media or paper, postage, and any summary you agreed to (45 CFR 164.524). NCI advises contacting the second-opinion center in advance about availability, costs and shipping. Ask your insurer too, since some policies have rules about second opinions (ACS).
