Hello.
The father of my wife and its or his mother had a leukosis. What probability of its or his display at the wife and how it is possible to check up this heredity (the genetic analysis?) and if she will prove to be true - that what to do or make as much as possible to be protected from disease?
In advance thanks for the answer!

The leukosis is not hereditary disease. There can be only a hereditary predisposition. Proceeding from it or this probability to define or determine it is impossible. Also the leukosis is not the homogeneous nosological form. Inside of it or her there is a set of different variants. Priventivnyh measures do not exist.
