All you must know about Irrfan Khan's rare disease

Bollywood actor Irrfan Khan, who shocked everyone by revealing that he is suffering from a rare disease a few days ago, had finally revealed he has been suffering from. He said that he’s suffering from Neuroendocrine Tumour.
 

 
As we wish Irrfan a quick recovery, here’s a quick look at what experts say about Neuroendocrine Tumors — the condition he has been diagnosed with:
 
 
1. They are rare tumors
Neuroendocrine Tumours (NETs) are considered to be rare tumors that typically develop over a number of years and grow at a slow pace. These tumors are considered to be more common in males in the age group 30-50. It occurs in less than one per million cases.
 
2. They develop in the hormone system
At the outset, “Neuro” means nerve and “endocrine” refers to the cells of the endocrine system. The neuroendocrine system, which is made up of glands and nerve cells, is where these tumors originally develop.
The neuroendocrine system is more commonly referred to as the hormone system as it is these glands and nerve cells that produce hormones in the body and then release them into the bloodstream.
 
3. These tumors can be benign or malignant
NETs are of two types — benign (non-cancerous) or malignant (cancerous). The slower the tumor develops, the higher chances there are of it being non-cancerous in nature.
 
4. They can spread to other parts of the body, but not always.
NETs originate in cells of the neuroendocrine system but have the potential to spread to other parts of the body, depending upon when the patient is diagnosed.
 
5. What are the symptoms?
These tumors are hard to diagnose and are commonly misdiagnosed as Irritable Bowel Syndrome (IBS) because the symptoms are said to be similar.
 
Experts say that the symptoms of NET could be everyday niggles and are often overlooked by patients. Symptoms are said to include (but aren’t limited to) constant headaches, rashes, a fast heartbeat and/or chest pain, weakness, weight gain or weight loss without trying, prolonged stomach pain and night sweat, among others.
