NET cancers are difficult to detect for a number of reasons:
- Size – they are often small; some NET cancers can be less than a centimeter in size
- Location – NET cancers can occur almost anywhere in the body
- Symptoms – these can vary enormously, and some patients have no symptoms at all
- Testing – there are many different types of NET cancer, and a series of specialized tests is necessary. A biopsy is a definitive tool for a NET cancer diagnosis.
