For years, cancer doctors have known that many patients aren't helped by the drugs they're given. For instance, only 20 per cent of those with advanced lung cancer will benefit from certain drugs.

Even among those receiving a very effective drug such as tamoxifen for breast cancer, 30 per cent don't respond.

The trouble is that, until now, there hasn't been any reliable way of working out who will do best on which treatments. But that is about to change. An important study has found that people with a certain type of gene won't benefit from selected cancer drugs.

This is hugely significant because it means gene tests can be used to work out which patients will do best on a drug, and as a result cancer treatments will become much more effective.

I wasn't sick for more than 12 years now...While I was studying I never missed a lecture because of my sickness (though sometimes I wanted that a lot J ) When I started working - I didn't get a chance to get sick either... Sometimes I'm wondering: am I just lucky or are there any other reasons for this?

One warm and sunny day I decided to go for movie. I called up few my friends to join me, but they were sick or were feeling weak. I thought to myself - why the hell they are sick, when outside was such a nice day and when it seems there is no reason to be sick. I was a bit upset to miss that movie, so I invited my neighbor (he wasn't a person I like to go out, but I said to myself «let it be» better him than to go on my own). On my way I started thinking, what is a secret of my pretty good health? J Its seems I live the same life as they do: I sleep, eat, work, and sometimes don't work. After some analysis I came up with some conclusions:
