Yes, a carcinoid tumor is considered a type of cancer. Carcinoid tumors are slow-growing tumors that originate in the hormone-producing cells of various organs, most commonly in the gastrointestinal tract and the lungs. They are part of a group of cancers known as neuroendocrine tumors.
Carcinoid tumors can secrete hormones that can cause symptoms such as flushing, diarrhea, and heart valve problems. These tumors can spread to other organs and tissues, but they tend to grow slowly and may not cause significant health problems for many years.
The best course of treatment is usually determined by the size, location and the extent of the tumor in the body, as well as the overall health of the patient.
