If the problem is an under-active gene, then science can look for ways to turn on the gene or supplement the protein it makes. Trials of gene therapy in colorectal cancer are already underway. Researchers are putting genes into tumors that will make them more sensitive to existing medications. They are also inserting genes designed to stop or slow down the growth of the tumor. These trials are in the early stages.
Gene testing can determine early who in the family carries dangerous genes.
Preventive therapy can then be prescribed, ranging from careful observation to surgery. Early diagnosis may also be possible as our genetics knowledge increases. Because cells are constantly shed from the colon, the DNA from tumor cells should be present in feces. And, as far as prognosis goes, recent genetics research has already shown that certain gene patterns in colorectal tumors predict a better outcome. To help those who are already ill, consider donations of money or time to charitable causes sponsoring research into colorectal cancer.
