A longitudinal study of women from Oakland California has been following 19 thousand of their offspring since the early 1960s.
So far 68 people have been diagnosed with colorectal cancer.
Risk factors include: obesity in the mother, weight gain during pregnancy, and a high birthweight. This suggests that uterine life has something to do with why this cancer develops. This could explain why there has been a relatively recent increase in colorectal cancer in younger aged adults. Unfortunately there is little you can do yourself about these factors.
