If neuroendocrine tumours (NETs) spread

Cancer cells can spread from the organ where they started to other parts of the body. This spread is called metastasis.

Understanding how a type of cancer usually grows and spreads helps your healthcare team plan your treatment and future care. If a neuroendocrine tumour (NET) spreads, it can spread to the following:

  • tissues or structures near the organ where the cancer started, such as the peritoneum, the pleura or fat tissue
  • lymph nodes around where the cancer started (regional lymph nodes)
  • liver
  • lungs
  • pancreas
  • bone
