Thank you for your concern, both of you. That is warming!
I guess it is one particular issue that at this moment worrying me:
My Dad noticed this spring that he had some difficulties swallowing when eating, but he didn't regard it as more than a nuisance he wouldn't bother the doctor about.
This condition lasted and didn't worsen (at least, that is his perception of it) until October, when he figured he ought to see a doctor after all.
That he had a tumour was fairly rapidly established, and he was scheduled for radiation therapy over two weeks ultimo November/primo December.
The result has been rather alarming:
His condition has over these two weeks rapidly worsened!
It is, of course, to be expected that the radiation therapy kills off quite a few healthy cells, and thus that it should be expected that his throat should become more sore than it was prior to the therapy.
However, he feels that the tumour seems to have grown, rather than shrunk, and here's basically what I would like to ask:
a) Since it is well known that radiation (may) induce mutations in cells, can it be the case that his tumour cells have mutated into a rather more nasty, aggressive type than previously as a direct result of his radiation "therapy"?
b) One of the distinguishing marks between a "benign" and "malign" tumour is that the benign tumour encapsulates itself in a coat, preventing metastasis, for example.
But:
Is it not possible that the body as a response to the growth of a tumour tries to section it off (however inadequate that response is in case of malign tumours)?
Could therefore the destuction of healthy cells around the tumour (as will happen in radiation therapy) disrupt the weak, natural protection we have, and hence, accelerate the tumour growth?
