Chronic stress promotes the development of tumor cells, experts advocate better management of women affected by endometriosis and genetics play a role in insomnia. Here are the three news of the day.
Cancer: chronic stress promotes the development of tumor cells
Increasingly understood and taken into account by the scientific community, chronic stress has already been the subject of many studies. All have shown that a long and intense period of stress can have a lasting effect on the psychological and emotional well-being, as well as the physical health, of the people who are subjected to it. Previous research has suggested, for example, that stress exposure can accelerate cancer growth by altering gene activity. Others have suggested that stress exposure could accelerate cancer growth because of its impact on gene activity. New work, conducted by Dalian University in China and reported in the Journal of Clinical Investigation go further. By conducting a study on mice, her authors discovered how chronic stress can promote the development of breast cancer stem cells. To read more click here.
Endometriosis: how to better care for women who suffer from it?
Seven to twelve years: this is the average time that women suffering from endometriosis must wait between the appearance of the first symptoms and the diagnosis of their disease.

Yet endometriosis is far from a rare disease, affecting about 10% of women of reproductive age, or about 200 million women and adolescent girls around the world. A working group of the Society for Women's Health Research has published avenues to explore to improve the diagnosis, treatment and access of women with endometriosis to quality care.

Brain cells genetically predispose to insomnia
The hours scroll on the clock radio and we can count the sheep, sleep refuses to come ... Real plague, chronic insomnia are a reality for many French.

In addition to the inevitable fatigue, people with insomnia are also more prone to drowsiness, depression or mood disorders. New work carried out by an international team of researchers and published in Nature Genetics could change the game. By assessing the sleep and genetic data of 1.3 million people, the authors identified for the first time the cell types, areas and brain processes involved in the genetic risk of insomnia.
