Neuroendocrine Cancer Symptoms

NET cancers are difficult to diagnose. After the onset of symptoms, which are often nonspecific and vague, a diagnosis can take an average of 3 – 7 years. If NET cancers are detected early in their development, they can often be cured with surgery. At present, however, most NET cancers are diagnosed at a later stage, when they have already spread to other parts of the body. In these cases, they can rarely be cured, although the symptoms can often be managed successfully for a number of years.

The symptoms of NET cancers can vary, depending on the location and biological properties. Very often, the symptoms are similar to other, more common conditions. Early symptoms may include vague tiredness or digestive complaints, or there may be no symptoms at all.

Some typical symptoms include the following:
