Seems this newfound ability to detect cancers earlier than we thought possible could be used to develop better treatments to boost the body's innate ability to eliminate cancerous cells before they turn malign: 1) identify thousands of people with traces of cancerous DNA that are too weak to merit immediate action and who are willing to participate in a trial. 2) Divide them into two groups, one group gets for one month a daiiy dose of auricularia auricula fungus extract or whatever that is believed to possibly prevent cancers from developing, the other group gets a placebo. 3) Run the early-detection test again at the end of the month to see whether or not there is a difference in cancerous DNA signal strength between the two groups.
