If you were to go to the American Cancer Society website looking for a list of Known Carcinogens (substances that are known to cause cancer in humans), you would find references to two lists compiled by the International Agency for Research on Cancer (IARC) and the National Toxology program. The ACS concurs with these agencies methodologies in compiling each list. The National Toxology program lists 56 substances. The IARC lists 107 substances and provides a lengthy paper on their website for each substance, outlining the reasons for classifying it as a carcinogen. The consensus on these lists will not provide many surprises: Tobacco, Ultraviolet Tanning Beds, Asbestos, and Estrogen-Progesterone Oral Contraceptives among others.
Recently, the news has been full of stories on a contraceptive medication for males. Researchers seek to “even the playing field” when it comes to contraception options. Development of a male birth control pill is being explored, but many methods being considered are not pills at all. No matter the prescription, there are some important things to know about the options being pursued.
