Neuroendocrine tumours (NETs) are a type of cancer that occurs in the hormone-producing cells of the body’s endocrine system. Neuroendocrine tumours can arise from many different parts of the body, including the pancreas, small intestine, rectum, lungs, and thymus. There are several types of NETs, each with different characteristics and treatment options.
The most common type of NETs are carcinoid tumours, which typically originate in the small intestine or rectum. These tumours generally grow slowly and can spread to other areas of the body, such as the liver. They may produce hormones, which can cause a wide range of symptoms such as diarrhea, flushing, wheezing, and abdominal pain.
Pancreatic NETs are less common than carcinoid tumours but can be more aggressive. These tumours can arise in the head, body, or tail of the pancreas and may produce hormones, leading to symptoms such as abdominal pain and weight loss.
Thymic NETs are found in the thymus gland, located in the chest. These tumours are rare but can cause chest pain, cough, and difficulty breathing.
Pheochromocytomas are tumours that arise from the adrenal glands, located near the kidneys. These tumours can cause high blood pressure, headaches, chest pain, and sweating.
Paragangliomas are rare tumours that can develop in the adrenal glands, neck, or other areas of the body. These tumours can cause a range of symptoms, such as high blood pressure, palpitations, and headaches.
Finally, medullary thyroid cancer is a rare type of NET that occurs in the thyroid gland. This cancer can cause a range of symptoms, such as a lump in the neck, hoarseness, and difficulty swallowing.
In conclusion, there are several different types of neuroendocrine tumours, each with different characteristics and treatment options. It is important to seek medical attention if you experience any of the symptoms associated with NETs, as early diagnosis and treatment can help improve outcomes.
