Separate recurrence from progression
Recurrence means cancer has returned after a period when it was not detected; progression means existing disease has worsened. Distant spread retains the original cancer identity. For example, breast cancer in the liver remains metastatic breast cancer.
Rebuild the treatment timeline
Record each regimen, the best response, when progression occurred and why treatment stopped. A new biopsy or molecular test may be useful when it could change the next treatment choice. Existing toxicity and organ function also influence sequencing.
Align treatment with your priorities
Discuss disease control, symptom relief and the burden of treatment together. Systemic therapy, selected local treatments and supportive care may serve different goals; the plan should make those goals clear.

Advanced therapies & clinical trials
When reviewing a new option, separate the evidence for the treatment from the practical route to receive it. An approval in one country does not establish availability or eligibility elsewhere.
| Option | What to verify |
|---|---|
| Approved treatment | Exact indication, age group, treatment line, biomarker requirements and the current local prescribing information. |
| Clinical trial | Recruiting site, inclusion and exclusion criteria, prior therapies, travel and follow-up requirements. Participation is not guaranteed. |
| Off-label or special access | Clinical rationale, local legal route, risks, costs and the treating institution’s ability to provide follow-up. |
Preparing for a second opinion
A second opinion is especially useful when pathology is uncertain, several treatment paths are possible, disease has returned or a new therapy is being considered. Coordinate timing with the treating team so necessary care is not delayed.
- Pathology report and access to tissue slides or blocks
- Imaging reports and the actual scans, with dates
- Molecular and biomarker reports, including the test method
- Treatment names, dates, response and major side effects
- Current medicines, other conditions and the questions you want answered
