New Hampshire wants to educate women.

(e) Materials that inform the pregnant woman that there is evidence of a direct link between abortion and breast cancer. It is scientifically undisputed that full-term pregnancy reduces a woman’s lifetime risk of breast cancer. It is also undisputed that the earlier a woman has a first full-term pregnancy, the lower her risk of breast cancer becomes, because following a full-term pregnancy the breast tissue exposed to estrogen through the menstrual cycle is more mature and cancer resistant. In fact, for each year that a woman’s first full-term pregnancy is delayed, her risk of breast cancer rises 3.5 percent. The theory that there is a direct link between abortion and breast cancer builds upon this undisputed foundation. During the first and second trimesters of pregnancy the breasts develop merely by duplicating immature tissues. Once a woman passes the thirty-second week of pregnancy (third trimester), the immature cells develop into mature cancer resistant cells. When an abortion ends a normal pregnancy, the woman is left with more immature breast tissue than she had before she was pregnant. In short, the amount of immature breast tissue is increased and this tissue is exposed to significantly greater amounts of estrogen—a known cause of breast cancer. Women facing an abortion decision have a right to know that such medical data exists. At the very least, women must be informed that it is undisputed that pregnancy provides a protective effect against the later development of breast cancer. - HB 1659 - 2012  [1]

If it is undisputed that the earlier a woman "has a first full-term pregnancy, the lower her risk of breast cancer becomes," New Hampshire should legislate that Junior High and High School women have this information. Why only legislate this information for the 1/3 of women that will get an abortion? I am sure that there are childless third year graduate students that need to know.

Some quick references:

...The average age of first-time mothers in the U.S. jumped from 21.4 in 1970 to 25 in 2006, an increase of 3.6 years, according to a report in the August edition of NCHS Data Brief, a publication of the CDC's National Center for Health Statistics... The average age at first birth has risen five years or more in Washington, D.C., Massachusetts, and New Hampshire, while increasing less than 2.5 years in Mississippi, New Mexico, and Oklahoma...

The median age for first marriage is 28.7 for males and 26.7 for females. [3]
