Now you see my enthusiasm for the possibilities! Imagine being able to take a biopsy, culture the tumor into many small replicates, and then testing each in real time to old drugs, new drugs, different doses, etc. such an approach could speed up the process of finding both individual and generic means by which to both slow down and stop the tumors.
It appears that the research team has been able to grow breast, lung, and a few other cancers in the lab. I want to add CC with the same goal as the published work, finding a way to end the insanity of surgery being the only option for he majority and offering a faster way to find new ways to eradicate the repeat occurrence of after the fact tumors.
