There is no single number, and any site that gives you one is guessing. Cancer covers hundreds of diseases at different stages; a diagnostic workup, a course of chemotherapy, surgery with recovery and weeks of daily radiotherapy are completely different trips. What is documented is this: a written second opinion takes 1-2 weeks and requires no travel at all, and any stay longer than 90 days needs a German national visa applied for at least 8 weeks in advance.
So the honest answer is that your stay length comes out of the treatment plan — and you can get that plan before you book a flight.
What Is Actually Documented
| Step | What’s known |
|---|---|
| Written second opinion | German cancer centres typically respond within 1–2 weeks of receiving records. No travel needed |
| Stay up to 90 days | No national visa needed for visa-exempt nationalities; Schengen rules apply |
| Stay over 90 days | National visa (Type D) required, with a hospital letter stating the plan and expected duration; apply 8+ weeks ahead |
| Cost of diagnostics | Comprehensive workup from ~€5,000 |
| Cost of treatment | Short-course chemotherapy packages from ~€8,000 per cycle; stage I–III breast cancer €45,000–85,000 for a full course; complex cases can exceed €300,000 |
| Payment | Hospitals price each case individually after reviewing the diagnosis, and international patients generally pay in advance |
What Changes the Answer
The step you’re actually coming for. A second opinion needs no trip. Diagnostics alone are usually a short visit. Surgery means admission plus recovery before you’re fit to fly. Radiotherapy is typically delivered in daily sessions over weeks, so it’s the longest stay of all.
Whether treatment can be split. Some patients have diagnostics and surgery in Germany and continue chemotherapy at home under their own oncologist. Ask directly whether your plan allows it — it can turn months abroad into a couple of weeks.
The 90-day line. If the plan runs past 90 days, the visa becomes the constraint, and it needs the hospital’s letter first. That sequencing is the part people most often get wrong.
Complications. Any honest estimate is conditional. Build slack into flights and accommodation rather than booking the minimum.

Who Germany Doesn’t Suit
Germany is expensive, and for a standard protocol available at home the cost is hard to justify. It earns its price for rare cancers, complex cases, a disputed diagnosis, or access to a therapy unavailable where you live. If cost is the constraint, India and Turkey deliver mainstream oncology for a fraction of these figures — our cancer treatment in Germany guide covers what the German premium actually buys.
What to Bring
- All imaging on disc — the scans themselves, not only the reports
- Pathology reports, and ideally the tissue blocks or slides, which German centres often re-analyse
- A treatment summary: what you’ve had, when, at what dose, and how you responded
- Current medication list and recent bloodwork
- Your passport and, if the plan runs past 90 days, the hospital’s letter for the visa application
Getting Started
Send your records for a written second opinion before booking anything. It takes 1–2 weeks, costs far less than a trip, and produces both the plan and the duration letter you’d need for a visa. See verified oncology clinics in Germany, or ask our AI assistant — describe the diagnosis and stage.
