Tomorrow's Health: Breast Cancer Risks Under New Guidelines


Story Updated: Jul 2, 2013

Two new studies suggest cancer may go undetected in some women under the revised mammography guidelines.

In 2009, the U.S. Preventive Services Task Force recommended testing every two years for women ages 50 to 74. Previously, all women over 40 were routinely tested.

Researchers at New York Presbyterian Hospital say in their study nearly 20 percent of cancers detected from a mammogram were in women in their 40s.

Pollution, Autism Linked

Air pollution could affect your child's risk of getting autism even before he or she is born.

Researchers at the University of Southern California say exposure to traffic-related air pollution can have an impact while the baby is in the womb and up to a year after birth.

The study looked at more than 500 children and found kids exposed to the highest levels of air pollution from traffic were three times more likely to develop autism.

HIV Risks

A new report finds that 60 percent of young people with HIV don't know they have it.

The CDC says in 2010 there were about 12,000 new HIV infections among people ages 13 to 24.

Gay and bisexual men, and African Americans are affected most. Doctors say many are not aware they are infected because only a small percentage are tested regularly.
