Women who exhibit many classic symptoms of post-traumatic stress disorder (PTSD) may be much more likely to develop ovarian cancer than their counterparts who don't, a new study suggests. For the study, researchers asked women to identify the most stressful event of their lives and report whether they experienced seven different symptoms of PTSD. Women who suffered from six or seven PTSD symptoms were more than twice as likely to develop ovarian cancer as women who didn't report any of these symptoms, the study found.
"We hypothesize that stress hormones directly affect cancer cells that may be in the body, causing them to grow faster and become more invasive," said Andrea Roberts, lead author of the study and a research scientist at the Harvard T.H. Chan School of Public Health in Boston. Ovarian cancer is the deadliest gynecologic cancer and the fifth most common cause of cancer-related death among U.S. women, Roberts and colleagues note in Cancer Research.
Animal studies have shown that stress and stress hormones can accelerate ovarian tumor growth, and that chronic stress can result in larger and more invasive tumors, researchers note. Previous research also suggests that mood disorders like depression and anxiety are associated with an increased risk of certain cancers.
In the current study, researchers examined data on 54,710 women who participated in a health study of U.S. nurses from 1989 to 2015. Every two years, women were asked about any ovarian cancer diagnosis; in 2008 participants were also asked about any traumatic events they had experienced and any related PTSD symptoms. After up to 26 years of follow-up, 110 women had developed ovarian cancer.
Overall, 15,378 women, or about 31%, didn't report any traumatic experiences like an assault or car accident. Another 9,482 women, or 19%, had been exposed to trauma but didn't report any PTSD symptoms. Almost 8% of the women did have a traumatic experience and four to five PTSD symptoms, and another 4.5% had a history of trauma and six or seven PTSD symptoms.
While women with four to five PTSD symptoms appeared to have a higher risk of ovarian cancer than women with none, the difference was too small to rule out the possibility that it was due to change. The study wasn't a controlled experiment designed to prove whether or how traumatic events or PTSD symptoms might directly cause ovarian cancer.
Still, the findings indicate that having higher levels of PTSD symptoms, such as being easily startled by ordinary noises or avoiding reminders of the traumatic experience, can be associated with increased risks of ovarian cancer even decades after women experience a traumatic event, researchers conclude.
