Endocrine tumours

Endocrine tumours are usually non-cancerous (benign). But some are cancerous (malignant).

What are endocrine tumours?

The endocrine system is made up of glands. Endocrine glands produce hormones. Hormones are chemical messengers that help control how organs and tissues in the body work.

Endocrine tumours are usually non-cancerous (benign). But some are cancerous (malignant).

The endocrine glands include the:

  • adrenal glands – glands that sit on top of each kidney.
  • pancreas – an organ behind the stomach which is part of the digestive system but also part of the endocrine system.
  • parathyroid glands – glands which are just behind the thyroid gland
  • pituitary gland – a small, oval-shaped gland at the base of the brain
  • thyroid gland – a gland in the front of the neck.

The language we use


We want everyone affected by cancer to feel our information is written for them.


We want our information to be as clear as possible. To do this, we try to:

  • use plain English
  • explain medical words
  • use short sentences
  • use illustrations to explain text
  • structure the information clearly
  • make sure important points are clear.

We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
