(CBS)- Researchers say women who have mutations in the "PAlB2" gene have a 1 in 3 chance of developing breast cancer. The gene is most associated with breast cancer, after the BRCA genes. British scientists looked at several hundred women with the rare gene mutations. They say if a woman carries the mutation, she should undergo additional breast cancer screening.
(CBS)- Stress during pregnancy could affect pregnancies for several generations. Canadian researchers studied generations of rats and found those subjected to stress late in pregnancy had daughters and granddaughters that had shorter pregnancies. The study also found other signs of stress in rats born to stressed grandmothers or mothers, including a lower birth weight and higher glucose levels.
(CBS)- U.S. researchers have discovered that analyzing the bacteria in a person's gut is a good indicator of who may have precancerous polyps as well as invasive colorectal cancer. They say it is better than assessing risk factors and stool testing. Scientists hope the technique could one day be used as a screening tool.
