Will genetic engineering in the near future be capable of causing cancerous cells to self destruct like they're supposed to?
The First Dragon
Yes maybe; a gene that would kill or correct cancerous DNA might be carried into the body by way of a genetically engineered virus.
This kind of questions can only come from people who never read...
Probably not. The only way to do that would be to genetically alter the DNA in the sperm and/or egg so that all cells have the right stuff. Right now, there is not even a theoretical genetic change that would be capable of eliminating cancer and even if there was, that type of genetic engineering is illegal virtually everywhere in the world.
There is no profit in finding cures.
