Aerobic exercise influences the way our bodies break down estrogens to produce more of the ‘good’ metabolites that lower breast cancer risk, according to a new research.

Observational studies suggest physical activity lowers breast cancer risk, but there are no clinical studies that explain the mechanism behind this, said Mindy S Kurzer, PhD, professor in the Department of Food Science and Nutrition at the University of Minnesota in Saint Paul.

"Exercise, known to favour fitness and improve heart health, is also likely to help prevent breast cancer by altering estrogen metabolism," said Kurzer. ANI

Doctors in Phoenix, found that the membrane surrounding Nagy’s brain had a hole in it and his "snot" was actually brain fluid that was leaking out, the Mirror reported. Nagy said that it first started when he sat up in bed one morning and a clear liquid dribbled out of his nose like tears out of eyes. ANI
