What happens after a cancer diagnosis?

Why more tests may be needed after diagnosis, how a treatment plan is discussed and what to ask at the next appointment.

Written and clinically reviewed by Dr AlHilali Consultant Clinical Oncologist

A cancer diagnosis is the start of a more detailed assessment. The next questions are usually what type of cancer it is, how far it extends and which treatments might help. Some answers may already be available; others need further tests.

There is no single sequence that everyone follows. A diagnosis found during surgery, for example, may lead to different appointments from one made after a scan or a small tissue sample.

Why are more tests needed if cancer has already been diagnosed?

A test that identifies cancer does not necessarily provide everything needed to plan treatment. A biopsy examines a sample of cells or tissue. Scans may investigate the extent of disease. Blood tests and other assessments can help the team judge how safely treatment could be given.

The pathology report may need additional testing to identify the cancer more precisely. Ask what each planned test is intended to answer and whether its result could change the recommendation.

A further test does not, by itself, mean that the cancer has spread.

Who brings the results together?

In the UK, many cancers are discussed at a multidisciplinary team meeting. Specialists consider the available results and possible options. You then need a conversation about what that recommendation means for you.

A clinical nurse specialist may be a useful contact between appointments. Ask who your main contact is and how to reach the service if symptoms change.

The treatment discussion

The team should explain the aim of treatment, likely benefits, important risks and reasonable alternatives. Your other health conditions, daily function and preferences also matter.

You do not need to understand every technical detail immediately. It is reasonable to ask the clinician to explain a term again or write down the main points. Bringing someone with you may help, if you would like that.

Before the next appointment

Keep a short list of questions:

  • What is confirmed, and what are we still waiting to find out?
  • Which tests or appointments happen next?
  • When and how will I receive the results?
  • What symptoms should I report before then?
  • Who should I contact if an appointment or result does not arrive?

If the expected date passes, contact the team rather than trying to infer the result from the delay. How long a result takes is not a reliable guide to what it will show.
