what happens to debris inhaled in the lungs?
« on: 21/01/2010 21:30:05 »
I  do a lot of DIY and sometimes inhale small particles unavoidably. How do the lungs clear out non-digestible debris eg small pips, pieces of tissue and metal filings, or is there some debris that stays there for life (unless you cough it up)? I read about a man who underwent surgery for lung cancer and the 'tumur' turned out to be a tiny growing fir tree from a seed he inhaled!

I thought this sounded a bit unreal but it was reported in the Telegraph

It does say, however
There was no independent verification of the surgeon's claims.

The Guardian

and Sky News
"It is absolutely impossible for a green plant to grow from this small seed inside a man's body. In order for a plant to start growing from the seed, it needs a lot of conditions - light, then water and certain temperature," said Olga Baranova, a university professor.

If anything, the 'tree' looks more like a small twig that's broken off a tree, there are no roots etc so it couldn't have 'grown' inside him could it?
