There has been a surge in cases of anal cancer. You ask why the increase in cases? Many cancers are because of chemicals, like BPA. Have you considered the chemicals present in toilet tissue? It goes on our most tender regions so perhaps it should be as pure as possible. As far as I know, the bamboo toilet tissue from Mercola.com is the only toilet tissue that is BPA free. And, it is good for the environment. Bamboo is so plentiful and grows so quickly. It replenishes itself with amazing speed. Consider it environmentally friendly.
If you have a family history of anal cancer or you have anal fissures or hemorrhoids, you might want to do all you can to ensure your anal health by investing in toilet tissue without chemicals.
