After so many years of research and funds donated, why isn't cancer or AIDS curable?

Let's see I would say that cancer is curable now, if detected early. The problem is that many people don't go to the doctor for regular check ups. In the case of AIDS is caused by a virus. The scientific community knows little about viruses, and the HIV virus is constantly mutating, making it difficult to find something that would stop it. They might find something that works for a certain strain of a virus but soon that strain will mutate, so the it won't work. I hope that help you a little to understand that even with the resources it is not easy to find cures to things that are constantly changing.

Mostly because both of these diseases mutate quite a bit. AIDS for example will mutate from person to person, depending on the immune system of the infected person.

Of course, if you are into conspiracy theories, there is the idea that it is more profitable for the drug companies to NOT find a cure. Pills for years earn LOTS more money than a one-time cure.

I think it's because the goverment doesn't want these to be cured.. Less money in their pockets.

they at one time did and come to found out it was to cheap to sell it and the could not make no money so the did not sell it. for ids anyway. as far as cancer there is things out ther that can cure it. but it cost alot.

Cancer can be prevented by eating a plant based diet, staying physically active, and maintaining a healthy weight. Conversely, if you are fat and sedentary, you are asking to get cancer.
Health is a choice you make.

Because in the bible it says that man will destroy its self and that there would be sickness that no man could find a cure to..

Along with Twalters comment, God is the only answer to the sickness and death. He promises to get rid of it. Revelation 21:4 While we can get better and better cures, we (people) will never get rid of it on our own. In response to another posters comment, you do not HAVE to be sedentary to get cancer, although you are right that it can contribute to it.

Both cancer and AIDS are diseases where the cells that are out of control are the body's own cells. Since they are not foreign, it's very difficult to kill the problem cells without killing all of the cells of the affected person.
