In women, only about 5-10% of breast cancer is inherited. Here spontaneous mutations play a much greater role. In men, on the other hand, the inherited form is … Is breast cancer hereditary?

How can we prevent transmission to children? It is generally difficult to prevent the development of schizophrenia. Numerous studies on this topic, such as the early administration of neuroleptics, have so far come to very heterogeneous results. In addition, the drugs used all have a broad spectrum of side effects. However, the consensus is that … How can we prevent transmission to children? | Is schizophrenia hereditary?
