Getting Diagnosed

You usually start by seeing your GP. They will ask you about your general health and symptoms and will also examine you. This might include listening to your breathing and seeing how much air you breathe in and out. Your doctor will then decide whether to do tests or refer you to a specialist.

When to see your GP

See your doctor if you notice a change that isn’t normal for you or if you have any of the possible signs and symptoms of cancer.

Even if you’re worrying about what the symptom might be, don’t delay seeing them. Your worry is unlikely to go away if you don’t make an appointment. The symptom might not be due to cancer but if it is, the earlier it is picked up, the higher the chance of successful treatment. You won’t be wasting your doctor’s time.

Try not to be embarrassed. What you tell your GP is confidential. Doctors are used to discussing intimate problems and will try to put you at ease.

Getting the most out of your GP appointment

When you see the doctor it can be difficult to remember everything you want to say. These tips will help you get the most out of your appointment.


  • Write down your symptoms including when they started, when they happen and how often you have them.
  • Write down if anything makes them worse or better.
  • Tell your GP if you are worried about cancer in particular.
  • Take a friend or relative along for support – they could also ask questions and help you remember what the GP says.
  • Ask the GP to explain anything you don’t understand.
  • Ask the GP to write things down for you if you think it might help.

What happens during your GP appointment

Your doctor will ask about your symptoms:

  • What they are?
  • When you get them?
  • Whether anything makes them better or worse.

They will also ask you about your general health.

When your doctor examines you, they may feel your lymph nodes (glands) in your neck and under your arms. They might listen to your chest by putting a stethoscope on your chest and back.

Tests your GP might do

Your GP might check your blood pressure, heart rate and temperature. They might also record your height and weight.

They might ask you to breathe into a small device called a spirometer. The device measures the amount of air you breathe in and out and also measures how quickly you breathe. This test is called spirometry.

After your examination, your doctor might refer you to a hospital to see a specialist or for tests.

Hospital tests

The GP might arrange for you to have blood tests. You usually have these at your GP practice or your local hospital. Depending on your symptoms, your GP can arrange some hospital tests, such as an x-ray.

What happens next

Make sure you know what happens next. Make another appointment if your symptoms don’t clear up, or if they change or get worse.

Questions you might want to ask your GP:

  • Do I need to see a specialist? Is it urgent?
  • When will I see them?
  • Will I find out about my appointments by post or telephone?
  • Do I need tests? What will they involve?
  • How long should I expect to wait?
  • Where can I find out more about tests?
  • Do I have to do anything in preparation for this test?
  • When will I get the results and who will tell me?

Your GP might not be able to answer all of your questions. They will tell you what they can at this point. Not knowing is difficult to cope with and can make you anxious.

If they don’t think you need any tests or a referral, perhaps ask your GP:

  • Can you explain to me why I don’t need to have tests or see a specialist?
  • Is there anything I can do to help myself?
  • Do I need to see you again?
  • Who do I contact if my symptoms continue or get worse, especially during the night or at weekends?

Making a GP appointment

You can book an appointment by telephoning your GP surgery or in person. You don’t have to tell the receptionist what you want to see the doctor for. Try different times of the day if it’s difficult to get through by phone. Accept a booked appointment, even if you think it’s a long time to wait. You could ask about cancellations if you are able to get to the practice at short notice.
