Bollywood actor Irrfan Khan was diagnosed with a neuroendocrine tumour in March

Bollywood actor Irrfan Khan, who was recently diagnosed with neuroendocrine cancer, has written about his fears and his struggles so far with the condition. A rare form of cancer, neuroendocrine disorders can be fatal in some cases. Steve Jobs is another well-known figure who was diagnosed with a neuroendocrine cancer, in his pancreas.
The NCI (National Cancer Institute of the United States) Dictionary of Cancer Terms defines a neuroendocrine tumour as one that forms from cells that release hormones into the blood in response to a signal from the nervous system. Most commonly occurring in the liver, the tumour may also be in the pancreas, lungs, skin or other organs of the body.
It is a near-fatal form of cancer, but this depends on various factors including early diagnosis, organs affected, stage of cancer, treatment trials and others. According to a 2015 research report, such cancers have an average survival rate of 5 years, which would mean that most patients survive for at least five years after diagnosis - but this again would depend on a multitude of factors.
Neuroendocrine cancers are usually slow-growing, and therefore, removal of the tumour is the preferred option. This method, after the tumour being diagnosed in early stages, is a good prognosis for most forms of the cancer.
Like other cancers, radiation, chemotherapy and targeted therapy are also common ways to manage the tumour - in case removal is not advised or if the cancer has spread to other organs (metastasis).
