Yes, Says New Study

1 Annual Mammograms for Women in Their 40s?

Women in their 40s with no family history of breast cancer are as likely to develop invasive breast cancer as are women with a family history, says a new study. In 2009, the US Preventive Svcs Task Force recommended against routine mammograms for women in this age group. Radiologist Dr. Stamatia V. Destounis, Elizabeth Wende Breast Care, Rochester, NY, reviewed data from patients, ages 40-49, who underwent screening mammography at her facility between 2000 and 2010. "In the 40-49 age group, we found a significant rate of breast cancer and similar rates of invasive disease in women with and without family history," says Dr. Destounis who adds that these results emphasize the importance of early detection and annual mammography for women in their 40s, regardless of family history.

Gene Changes May Be Important

2 Woman's Heart Risk May Begin in Womb

A woman's heart attack risk may rise before birth, find researchers in The Netherlands. The small study found that a woman's risk of experiencing a heart attack increased more than eight times if certain genes were changed. Previous research has shown that the gene changes are brought on by stress felt in the womb from not getting enough nutrients or other factors. According to MSNBC, researchers found that women with epigenetic changes or chemical "tags" in two of the genes were 8.6 times more likely to have a heart attack compared to women without the chemical tags on the genes. The research, published in International Journal of Epidemiology, also reveals that there was no association between the gene changes and heart attack risk for men.

Structural, Functional Changes

3 Psychopaths' Brains Work Differently

A study in which 40 prisoners, 20 of them psychopaths, had their brain scans revealed structural and functional differences between those with a disorder in which they do not feel empathy and guilt and those who do. Psychopaths do not have as many connections between the ventromedial prefrontal cortex and the amygdala compared to most people so the communication between the two is poor. The ventromedial prefrontal cortex plays a role in feeling guilt and empathy while the amygdala regulates feelings of fear and anxiety. This study is the first of its kind in showing both structural and functional differences in the brains of psychopaths and the researchers believe the results are important first step in understanding how the disorder starts and ways that it can be treated.
