A really working cancer drug would be a revolution in medicine. and people with only a small part of the rights (investment) to this drug could become very rich people. But the problem is that no one knows when such a drug will be created.
The main thing is that the people in the hands of who will have this medicine remain people and do not sell it for crazy money, so that they dont give a damn about other people's lives.
If they do not violate the laws and claims to them can not be. These are the realities of modern life. But I hope that there are people for whom money is not important and they just want to help other people.
