Lung

3D medical rendering of lungs and heart, highlighting the chest cavity—related to pulmonary neuroendocrine tumours.

Lung neuroendocrine tumours vary widely. Some grow very slowly and cause no symptoms at first, while others cause breathlessness or a persistent cough, or release hormones that affect other parts of the body. Learn how they are diagnosed and treated.

Gallbladder and bile ducts

Neuroendocrine cancer of the gallbladder and bile ducts is very rare, and often causes no symptoms at first. When symptoms do appear they can resemble those of more common gallbladder conditions, which can make it harder to diagnose. Here is what to expect.

Duodenum

Neuroendocrine cancers of the duodenum are uncommon, and many people have no symptoms in the early stages. Some duodenal NETs release extra hormones, causing acid reflux, abdominal pain or diarrhoea. Find out how they are diagnosed and treated.

Colon

Neuroendocrine cancers of the colon are rare and may cause no symptoms in their early stages. When symptoms do appear, changes in bowel habits or abdominal discomfort are easily mistaken for other, more common bowel conditions. Here is how they are found and treated.

Breast

Neuroendocrine cancers of the breast are rare. They include neuroendocrine tumours (NETs), which are usually slower growing, and neuroendocrine carcinomas (NECs), which grow more quickly. Learn how they are diagnosed, monitored and treated.

Appendix

Neuroendocrine cancers of the appendix often cause no specific symptoms and are frequently discovered during surgery for suspected appendicitis. Find out how they are diagnosed, graded and treated, and what follow-up you can expect.

Adrenal

Phaeochromocytoma is a rare neuroendocrine cancer that develops in the inner part of the adrenal glands. Some tumours release extra hormones, while others cause few or no symptoms. Learn about the inherited conditions linked to it, and how it is diagnosed and treated.

Cancer of unknown primary

Neuroendocrine cancer of unknown primary (CUP) is diagnosed when a neuroendocrine cancer is found, but the place it started cannot be identified even after specialist tests. Treatments can still be planned. Find out how, and where to get support.

Adrenal

Medical illustration of kidneys and adrenal glands, showing the anatomical location relevant to adrenal and kidney-related neuroendocrine tumours (NETs).

Adrenocortical carcinoma (ACC) is a rare cancer that starts in the outer layer of the adrenal glands, the small glands that sit above your kidneys. Some tumours release extra hormones. Find out about symptoms, diagnosis, treatment and living well with ACC.
