Why are NET cancers so often misdiagnosed?

Depending on where they are in the body, NET cancers can give rise to a wide variety of symptoms. These symptoms may be mild or nonspecific, and are often similar to those of other, more common conditions.

For example, many of the symptoms associated with carcinoid tumors are similar to those of Irritable Bowel Syndrome (IBS), Crohn’s disease, peptic ulcer disease, gastritis, other digestive disorders, asthma or pneumonia.

Many physicians are unfamiliar with NET cancers and therefore less likely to suspect a NET cancer in their initial investigations.
