Various medical literature seems to agree on consoling the sufferer, reassuring them they're not dying, and encouraging a full medical research stoppage. I feel like accepting death should be part of the therapy. We're all going to die, and someday that person will have to legitimately deal with it. If we can demystify death we can help them tackle their problem head-on, instead of just putting a blanket over it.

I'm not suggesting putting religion into it, reassuring that they'll go to heaven and be reunited with their dead pets and family members. Just try to have them understand that death is a very natural thing. If there is indeed a Hell and they fearing going to it, let them know that the good news is that they'll not be alone.

Hypochondria (rare, expensive, potentially dangerous) is not the same as fear of dying (normal, free, healthy).

The former is treated in the USA by bankruptcy. AFAIK there is no treatment available in civilised countries - it's just another burden on the taxpayer.

Fear of death (what happens after dying) is vital. Without it, thousands of religious professionals would be out of work. Problem is to eliminate that irrationality (religion being the cause of many wars) without provoking its opposite - religious fanaticism that leads to suicide bombing.

A grade 4 astrocytoma will quickly override hypochondria.

Realizing how many times I've thought I was dying before is one of the best things that helps me relax. On numerous occasions, I was convinced that "this is the end." But it never occurs. So, whenever a new symptom appears, I remember all of these times and realise that it is just a minor symptom that means nothing. Maybe just some annoyance or a headache. I hope this was helpful.

Another important factor is to keep yourself busy. Divert your attention as much as possible. And, if you're tired, go to bed; you don't want to lay there focusing on your symptoms.
