During leukaemia, a cancer of the white blood cells, the bone marrow, which produces blood cells, starts to churn out immature white blood cells. This changes the balance of the blood: The white blood cells are not properly developed so they cannot fight infection and there are too few red blood cells to carry oxygen around the body. The disease can be fatal within weeks if left untreated. And now three groups of mutations which cause acute myeloid leukaemia, have been identified by scientists. This could lead to new treatments.

This is obviously good thing, no doubt. But I've been playing with the idea what if the giant medicine firms are worse than you might think? Could it be possible that for example a cure for HIV has already been found like 10 years ago and the firms haven't published it yet because they can make more money by producing weaker medicines first. This is of course only speculation and hardly true, hopefully. It's still good to think about these things even if they seem far-fetched.
