PanARMENIAN.Net - New research that now appears in the British Journal of Cancer suggests that a person's history of mental health issues may raise their risk of dying from cancer following diagnosis, Medical News Today reports.
Though the cancer mortality rates in the United States have "declined steadily" during the past 20 years, it remains the second leading cause of death, both in the U.S. and globally.
Worldwide, about 1 in 6 deaths are attributable to cancer; in the U.S., cancer caused almost 600,000 deaths in 2016.
The World Health Organization (WHO) estimate that almost a third of cancer-related deaths are due to modifiable risk factors or behaviors.
These behaviors include not exercising enough, smoking, drinking, or not eating enough fruits and vegetables. However, new research adds another critical factor to the list of things that may influence a person's outlook once they receive a cancer diagnosis: mental health.
Researchers led by Zachary Klaassen, who is an assistant professor and urologic oncologist at the Georgia Cancer Center in Augusta, set out to examine whether a formal psychiatric diagnosis influences cancer survival rates.
Klaassen and colleagues examined the records of more than 675,000 people who had received a cancer diagnosis. The participants were all adults and received their diagnoses between 1997 and 2014.
Specifically, the study participants had received a diagnosis of one of the 10 most common types of cancer: prostate cancer, breast cancer, lung cancer, kidney cancer, bladder cancer, colorectal cancer, melanoma, endometrial cancer, thyroid cancer, or oral cancer.
Almost 50 percent of these people underwent a psychiatric evaluation as an outpatient, around 7,900 of them received urgent psychiatric help, and over 4,000 were admitted into the hospital because of a mental health problem in the 5 years leading up to their cancer diagnosis.
