relatively large number of colorectal cancers are occurring in people under 50,» says study author Samantha Hendren, M.D., M.P.H., associate professor
of surgery at the University
of Michigan Medical
School.
Given the
relatively small
number of students moving back and forth between charter
schools and district - managed
schools, it is unlikely these students would have a
large impact on the overall graduation rate.
