RE:RE:RE:RE:LABS said 'no' to AstraZeneca buyout offer....Astrazeneca purchased FUSN because it has patented technology for radiopharmceuticals that target specific cancers that AZ is interested in, and the trials are complete or near complete. In comparison. cannabiis as medicine is light years away from being an approved cancer treatment. Compared to FUSN, LABS is kindergarten.
