A new way to attack breast cancer tumors and new information about adolescent drug use.

A new survey finds more than 6 percent of U.S. adolescents used drugs to treat psychiatric or mental disorders from  2005-2010.  The National Health and Nutrition Examination Survey found use of antidepressants and ADHD drugs was highest and that males were more likely to use ADHD drugs.  About half the adolescents who reported using psychotropic drugs had seen a mental health professional in the last year.

Women who have mammograms every year have a better chance of detecting breast cancer before it has a chance to spread.    Researchers at Northwestern University found women who had  frequent exams showed a significantly lower rate of cancer cells in the lymph nodes.  The American Cancer Society recommends annual breast cancer screening beginning at age 40. But the US preventive Services Task Force recommends screenings every two years starting at  age 50.

Researchers in Italy are experimenting with focused ultrasound to heat and destroy breast tumors.  The technique uses magnetic resonance imaging to locate the lesions and monitor temperature change during the procedure.  It does not require any incision. Researchers say more study is needed before it  can be used as a stand-alone treatment for breast cancer.
