A new set of reports shows that federal policy on chemicals testing neglects breast health.

The last quarter of a century has taught science some apartment rental newfangled things about breasts. For one thing, they appear to be showing up earlier in young girls, with possible consequences for breast cancer later on. For another, the way they grow and develop varies from Новости туризма woman to woman, and—if lab animals are any indication—normal exposures to commercial chemicals can alter that process. The growing human breast is also more vulnerable than we thought. Data from atomic-bomb survivors in Japan show that it was adolescents—not grown women—near the explosions who Makeup school were most likely to develop breast cancer in later years. Since then, there's been similar data for girls who were exposed to medical X-rays or radiation therapy, as well as research showing that the pesticide DDT, now banned but pervasive in the 1950s and 1960s, is associated with a higher risk of breast cancer in women exposed as girls.
