Triple-negative breast cancers have an especially poor prognosis. And now an analysis in the journal Cancer Medicine finds that Black women have a higher risk of these kinds of cancer than previously known—nearly triple the risk of white women. What’s more, triple-negative negative breast cancers are less likely to be detected early. That is why scientists are excited about a new tool for breast cancer risk prediction in Black women described in a report in the Journal of Clinical Oncology. The tool could help doctors be more accurate in identifying women at a higher risk of breast cancer and refer them for early or more frequent screening.
Online dating violence begins at an early age—as early as age 12. A study in the Journal of Youth and Adolescence finds that about 15% of 6th graders are subject to electronic harassment or coercion to share sexual messages or pictures. By age 16, it’s nearly 40%, but researchers say the risk declines after that as more teenagers can drive to see their boyfriends or girlfriends in person.
And finally… science has conclusively proven something that makes common sense—when you are nice to others, they are more likely to be nice to you. The study in the Journal of Personality and Social Psychology shows that when people meet for the first time, they reciprocate each other’s behavior. They also project that the other person is a lot like them. The result is a new acquaintance is a lot like a mirror.
