  • Texas watershed cancer link

    A study in the Journal of Water and Health examines a possible link between an increased risk of childhood cancer and the geographic location of the mother at birth. This increased risk was estimated for each watershed in Texas. Although rare in terms of absolute numbers, cancer is the most common fatal disease among US children. The foetus has reduced resistance to toxic injury and is ...
