Breast cancer

Metastatic breast cancer spreads faster to women who suffered a traumatic or stressful event according to the University of Rochester Medical Center scientists. Studies show that women who endured a physical or a sexual abuse, see that the tumors return after 2-5 years, while other women with peaceful lives see recurrences after 5 years.
Scientists believe that stress can lead to breast cancer, and it affects the process of spreding killer cells through the body, they also relate the disease to the cause of a stressful event such as losing a loved one.Still, the research continues, as scientists are intrigued by the conflicting evidence.  
This research included, as well 94 women who were categorized by the experience they had, either traumatic or stressful with other women who had not faced similar situations.
They studied the cortisol levels from saliva samples from the participants. Cortisol is produced by the body when it faces stress and fear, and there is growing evidence that abnormally prolonged cortisol production inhibits the body's immune response. Palesh said:
"Extended periods of stress and trauma and its resulting cortisol production may interfere with the body's ability to fight off cancer progression. When there is consistent, long-term stress in the body, the elevated cortisol level may can change the body's normal rhythms and potentially reduce resistance to tumor growth."
I find this article very interesting, that's why I wanted to share it with you to. Personally, it's been a pleasure to find as much info as I can about cancer. Have a nice day and a healty life:)
