Yes, there is research being done on cancer prevention. Look up Dr. Nystul at UCSF and his research involving adult stem cells in drosophila ovaries. He talks about hypercompetition between cells and that it may be the answer to a possible mechanism for the exponential spread of cancer throughout the body. He has engineered cells to produce certain proteins and for some reason unknown at this point, cells containing those certain proteins are more likely to bump out other cells and take the place as the adult stem cell. This provides the possibility for engineering cells that can bump out cancer cells who have made their home as the adult stem cells in certain areas of the body.
