Cancer and the thyroid

Papillary thyroid cancer: symptoms, tests, treatment and outlook

Papillary thyroid cancer is the most common type of thyroid cancer. It usually shows as a painless lump in the front of the neck and is often treatable, with surgery as the main treatment. This guide explains symptoms, how it is investigated, what treatment involves, and how thyroid hormone replacement and follow-up work afterwards.

Key facts

At a glance.

  • The most common type

    Cancer Research UK says the most common type of thyroid cancer is papillary thyroid cancer, and that the type refers to the cell the cancer started in.

  • Quite rare overall

    The NHS describes thyroid cancer as quite rare in the UK, and says women are more likely to get it than men.

  • A hard painless lump

    The NHS says the lump in the front, lower part of the neck usually feels hard, slowly gets bigger and is not painful.

  • Generally good survival

    Cancer Research UK says survival is generally very good for papillary and follicular thyroid cancers, though it depends on type and stage.

  • Surgery is the main treatment

    The NHS says surgery is the most common treatment, either removing all of the thyroid or part of it, and that thyroid hormone tablets are usually needed afterwards.

  • Results in about 2 weeks

    The NHS says it should take about 2 weeks to get the results of tests, but sometimes longer, which does not definitely mean anything is wrong.

What papillary thyroid cancer is

The thyroid is a small gland in the front, lower part of the neck that makes hormones helping with things like digestion, muscles and heart. Thyroid cancer is cancer found in this gland. Cancer Research UK explains that the type of thyroid cancer depends on the type of cell it started in, and that papillary is the most common. Others include follicular, medullary and anaplastic, which are handled differently.

The NHS says how serious thyroid cancer is depends on the type, how big it is, whether it has spread and your general health. Cancer Research UK says survival is generally very good for papillary and follicular cancers, but that it depends on the type and stage, so your own outlook is best discussed with your specialist.

Symptoms and when to see a GP

The NHS lists the symptoms of thyroid cancer, and stresses that these are very common and can be caused by many other conditions.

  • A lump in the front, lower part of the neck, usually hard, slowly growing and painless.

  • A hoarse voice, a sore throat, or a cough.

  • Difficulty swallowing or breathing.

  • Pain in the front of the neck, or a feeling of something pressing against the neck.

  • Less commonly, flushing, softer poos or diarrhoea, and weight loss.

What to do and who to call

The NHS advises seeing a GP if you have a new lump in the neck or an existing lump that is getting bigger, a hoarse voice, sore throat or cough for more than 3 weeks, or pain or pressure in the front of the neck. It says to ask for an urgent GP appointment or get help from NHS 111 if you are having difficulty swallowing or breathing.

If you already have a swollen thyroid (goitre) or nodules, the NHS says to get checked by a GP if symptoms change, get worse or do not feel normal for you. The GP may feel your neck and arrange blood tests, and may give you an urgent referral, which does not definitely mean you have cancer.

Causes and risk factors

The NHS says anyone can get thyroid cancer and it is not always clear what causes it. You may be more likely to get it if you are a woman who has not been through the menopause, have a condition affecting the thyroid such as a goitre, Hashimoto's disease or non-cancerous nodules, have a close relative who has had thyroid cancer, were exposed to a lot of radiation or had radiotherapy in the past, especially as a child, or have had certain other cancers such as breast, oesophageal, testicular cancer or non-Hodgkin lymphoma.

Cancer Research UK adds age, being very overweight and some non-cancerous thyroid conditions to the risk factors. The NHS notes you cannot always prevent it, but keeping a healthy weight, cutting down on alcohol and not smoking can lower your chance of cancers generally.

How it is diagnosed and staged

The NHS says that if the GP refers you to a specialist you may have blood tests, an ultrasound scan of the neck and a biopsy, where a small sample is taken from the thyroid gland with a needle to be checked for cancer. You may not have all of these. It should take about 2 weeks to get results.

If thyroid cancer is confirmed, further tests help work out the size and how far it has spread. The NHS lists CT, MRI or PET scans and a test where a thin flexible tube with a camera is passed through the nose to check the vocal cords. Cancer Research UK explains that staging uses the TNM system, which looks at the size of the cancer, whether it has spread to lymph nodes and whether it has spread to other parts of the body, and that the number staging for papillary and follicular thyroid cancer is the same.

Treatment

The NHS says the treatment depends on the size and type of thyroid cancer, whether it has spread and your general health. It will usually include surgery and may also include hormone therapy, radioactive iodine treatment, targeted medicines, radiotherapy or chemotherapy.

Treatments for thyroid cancer described by the NHS
TreatmentWhat it involvesWhen it may be used
SurgeryAll of the thyroid removed (total thyroidectomy) or part of it (partial thyroidectomy or lobectomy), sometimes with neck lymph nodesThe most common treatment for thyroid cancer
Hormone tabletsTablets to replace the hormones the thyroid madeUsually needed after surgery to remove the thyroid, and can help stop the cancer coming back
Radioactive iodineA small amount of radiation taken as a tablet or drinkAfter surgery to kill remaining cancer cells, or if cancer has come back or spread
Targeted medicinesMedicines that aim to stop the cancer growingIf other treatments are not an option or no longer working, or cancer has spread
RadiotherapyHigh-energy rays to kill cancer cellsIf the cancer cannot be removed by surgery or has spread
ChemotherapyMedicines to kill cancer cellsNot usually used, but may be if the cancer has come back or spread

Follow-up and living with it

The NHS says you will have regular check-ups during and after treatment, and may have tests and scans. If you have symptoms or side effects you are worried about, you do not need to wait for the next check-up. A clinical nurse specialist is usually your main point of contact. Support is available from charities such as the Butterfly Thyroid Cancer Trust, Macmillan Cancer Support and Cancer Research UK, which the NHS lists in its help and support page.

NHS pathway or private specialist

On the NHS the route is a GP appointment, urgent referral where cancer is suspected, ultrasound and needle biopsy, then a multidisciplinary team that recommends treatment. Some people choose a private endocrine surgeon or ENT specialist for a quicker first appointment or a second opinion. Whichever route you use, it is worth asking which surgeon and team will manage each stage of care.

Frequently asked

Questions people ask.

Quick, plain-English answers to the questions we hear most.

  • Is papillary thyroid cancer the most common type?

    Yes. Cancer Research UK says the most common type of thyroid cancer is papillary thyroid cancer.

  • Does a thyroid lump mean cancer?

    No. The NHS stresses that these symptoms are very common and can be caused by many conditions, though they should be checked by a GP.

  • What tests are used?

    The NHS lists blood tests, an ultrasound scan of the neck and a needle biopsy. You may not have all of them.

  • Will I need my whole thyroid removed?

    Not always. The NHS says surgery may remove all of the thyroid (total thyroidectomy) or part of it (partial thyroidectomy or lobectomy), depending on type and stage.

  • Will I need tablets afterwards?

    The NHS says if you have had surgery to remove your thyroid you usually need hormone tablets to replace the hormones it made, and you may also need them if part has been removed.

  • What is radioactive iodine treatment?

    The NHS says it uses radiation to kill cancer cells, given as a tablet or drink, usually after surgery to kill any cells left behind or if the cancer has come back or spread.

  • What is the outlook?

    Cancer Research UK says survival is generally very good for papillary and follicular thyroid cancers and depends on type and stage. Your specialist can explain what this means for you.

  • Can I lower my risk?

    The NHS says you cannot always prevent it, but losing weight if overweight, cutting down on alcohol and quitting smoking can lower your chances of cancers generally.
