From suspicion to diagnosis: what the path looks like

The short answer

The path follows almost the same stages everywhere: suspicion, imaging, tissue sampling, laboratory result, then the treatment plan is set. A cancer diagnosis is not made from an ultrasound or a blood test — it is made by examining tissue. The order matters, and most delays happen between stages, not within them.

1. Suspicion. It can start from a symptom, a routine check-up, or an investigation done for something else. This is where it is decided whether rapid assessment is needed.

2. Imaging investigations. Ultrasound, X-ray, CT scan, MRI, or other methods, depending on the area. They show where the problem is and how extensive it appears, but they do not say what it is.

3. Tissue sampling. A biopsy or procedure. This is the step that confirms or rules out the diagnosis. Without it, there is no cancer diagnosis.

4. The laboratory result. The tissue is examined under the microscope, and afterward additional tests are often run on the same sample. These additional tests take time and are often the ones that change the treatment.

5. Staging. How extensive the disease is gets established, sometimes with further investigations.

6. The plan. This is usually discussed among several specialists, then presented to the patient.

A result from stage 4 without stage 5 is not yet a plan. That is why the answer to "so what do we do now?" comes later than everyone would like.

Start the file on day one. In three months you will no longer remember what happened when.

• Referrals, both original and copies.
• Every imaging result, plus the disc or files.
• The laboratory result, complete, with every page.
• Blood tests, in chronological order.
• Medical letters from every consultation.
• The list of medicines you take, including over-the-counter ones.

Ask for copies on the day you receive the result, not later. Also keep a version photographed on your phone.

Rarely within a single stage. Almost always between stages.

Time is lost when no one tells you who to see next. When a document is missing and you only find out at the counter. When the result is ready but no one calls. When you move to another hospital and the investigations are repeated from scratch.

That is why, at the end of every visit, it is worth leaving with the answer to two questions: what is the next step, and who does it.

Procedures, required documents, and what is reimbursed differ and change over time. Always confirm with your clinic and your insurance provider, not from an article or someone else's experience from two years ago.

What is worth asking from the start: what type of referral you need, whether a separate appointment is needed for each investigation, and who issues the documents you will need next.

If someone tells you a document cannot be obtained, ask who issues it and on what basis. Usually there is a path — it just has not been explained to you.

A nodule seen on ultrasound is not a diagnosis. A high value on a blood marker is not a diagnosis. A phrase like "suspicious appearance" on an imaging report is not a diagnosis.

These are reasons to go further, not conclusions. Many turn out to be something else.

• Which stage am I at now, and what is next?
• Who takes the next step: me, you, or another service?
• What documents do I need, and where do I get them?
• How long does the result take, and who will let me know?
• What happens if the result is not conclusive?
• Who do I call if no one contacts me?

Start your file today, even if it holds a single document. And at every visit, leave with two things written down: the next step, and the name of the person who does it. These are the two pieces of information most often missing, and they cost the most time.
