Neuroendocrine tumors (NETs) can occur at any age, but are most common in adults over the age of 60. They can occur in children, but are much less common.
What is a Neuroendocrine Tumor?
A neuroendocrine tumor (NET) is a type of cancer that usually develops in cells of the neuroendocrine system. The neuroendocrine system is made up of cells that produce hormones and release them into the bloodstream. NETs can develop anywhere in the body, but are most commonly found in the lungs, digestive system, and reproductive organs.
What Causes Neuroendocrine Tumors?
The exact cause of NETs is unknown. However, research suggests that certain factors may increase the risk of developing a NET, such as a family history of NETs, certain genetic conditions, and exposure to certain chemicals or radiation.
What Are the Symptoms of Neuroendocrine Tumors?
The symptoms of NETs vary depending on the location of the tumor and the hormones it produces. Common symptoms include abdominal pain, weight loss, fatigue, and diarrhea. Other symptoms may include skin flushing, headaches, and vision changes.
How Are Neuroendocrine Tumors Diagnosed?
NETs can be difficult to diagnose because the symptoms are often vague and can be caused by other conditions. Your doctor may order imaging tests, such as a CT scan or MRI, to look for a tumor. They may also order a biopsy to take a sample of the tumor to be tested.
How Are Neuroendocrine Tumors Treated?
Treatment for NETs depends on the size and location of the tumor, as well as the patient’s overall health and medical history. Treatment options include surgery, radiation, chemotherapy, targeted therapy, and hormone therapy.
What Is the Prognosis for Neuroendocrine Tumors?
The prognosis for NETs depends on the size and location of the tumor, as well as the patient’s overall health. Early diagnosis and treatment can improve the outcome. NETs can be slow-growing and may not require treatment in some cases.
