In a recent conversation with a friend of ours who is a doctor, we discussed the apparent increase of "rare diseases" that seem to be the "plague" of our modern world. This doctor is a prestigious nenatologist with over 30 years of experience, someonoe who knows what he is talking about. He expressed his concern, mentioning the fact that the hospital where he works has tripled its pediatric oncology medical team over the course of the last twenty years given that the incidence of childhood cancer, especially leukemia, is on the rise. According to this doctor, on average a case of leukemia is diagnosed "once a month and sometimes once a week." The conversation would definitely have proved most interesting, had it not been interrupted. I must admit, I had several more questions on my list for him.
