Childhood Sexual Abuse Increases Risk of Cancer in Adulthood

It has been well established that adverse childhood experiences (ACE) result in negative outcomes. People who have experienced neglect, emotional abuse, domestic violence, childhood sexual abuse, physical abuse, or other traumatic events in childhood are at increased risk for psychological and physical illnesses.

Divorce, death of a parent, caregiver mental illness, and other environmental factors also place children at increased risk for negative behaviors, including smoking, drug use, and sexual risk taking. Psychological illnesses such as post-traumatic stress, depression, anxiety and even suicidal ideation are often associated with ACE.

Some research has even suggested that ACE increases the likelihood of cancer and other chronic illnesses by way of risky and maladaptive behavior and through changes in physiological and biological elements during childhood. Specifically, incidences of lung cancer and heart disease have been found to be higher in people with ACE most often as a result of smoking. However, until now, no study has looked specifically at how ACE affects risk of all cancers in childhood and adulthood.

Monique J. Brown of the Department of Family Medicine and Population Health at the Virginia Commonwealth University School of Medicine in Virginia wanted to examine whether or not ACEs increased overall risk of cancer. Brown assessed a large sample of participants and evaluated their ACE in relation to either cancer in childhood or adulthood.

She found that over 60% of all the participants had experienced at least one ACE and nearly 10% had a history of cancer. Of all the types of ACE, childhood sexual abuse was the most common in those with adult cancer, but appeared to have little impact on childhood cancer. The rate of cancer prevalence among the participants with ACE was much higher than the national average of 4.2% and suggests that ACE, and in particular, childhood sexual abuse, has a strong indirect impact on cancer risk in adulthood.

Brown was unable to find any evidence of ACE influencing childhood cancer risk, which suggests that biological and physiological effects of ACE may have less of an impact on overall health than the behavioral and emotional impacts of ACEs. Brown believes that these results reveal a particular segment of the population in need of early intervention. She added, “More research should focus on the impact of sexual abuse ACEs and adverse health outcomes.”

    abuse can wreck havoc in a child’s could well change the way he or she sees the is well established that experiencing abuse can put a child at risk for smoking and substance abuse.

    now I am not surprised that this could predict cancer.because the abuse is pushing the child to behavior that lead to cancer.yes,this does need intervention.but what is needed even more is stricter laws and punishment for abusers.they are not just spoiling a short period of life of the child but are putting an entire lifetime at stake.

    Do you think that this could be caused by the buildup of stress in one’s body who has lived through this kind of abuse? I don’t see any other thing that could raise the numbers like this because the other environmental and genetic factors are going to vary from person to person.

    Through my years of experience treating survivors of adverse childhood experience, a good number of them have developed cancer as well as other serious conditions.

    I experienced childhood sexual abuse (father and brother) between the ages of 6 and 13. I have now been diagnosed with ovarian cancer at 71 and unlikely to live more than another 18 months to 5 years. I am wondering whether the deposition of sperm/genetic material regularly into the bodies of children with immature and developing reproductive systems sets them up for cancer/abnormal growths in later years as well as the stress of struggling with sequelae of ACE for decades.

    This is so insane. This is like saying Jewish usury probably causes cancer, but not through the usury itself but through the emotional turmoil Jewish financial exploitation causes. And then someone chimes in, “You know, I deal with many victims of Jewish bankers, and many of them caught the cancer!” It is 100% neo Nazi ideology, transmuted into “save the children”. You people are insane.

    Yes it does seem hard to believe, would be interesting to read how they came to this conclustion? Have you read any studies that offer a different opinion to this one?
