There may be a connection between stress and cancer. Sure cancer can
cause stress, but new findings may help us determine if stress can cause
cancer. Previous research from the National Institute on Aging suggests
that there may be link between chronic depression and cancer among older
Researchers found that when present for at least six years, depression
was associated with an increased risk of cancer. The study in 1998
found that the cancer rate among those depressed was 88 percent higher
than other patients, according to report from CNN.
Now ABC News reports that Dr. Charles Raison said, ”Inflammatory
pathways activated by stress have been implicated in the development of
tumors, metastasis of tumors, and resistance to chemotherapy.” Raison
is professor of psychiatry and behavioral sciences and director of the
Behavioral Immunology Clinic at Emory University in Atlanta.
Experiments in cell biology and biochemistry have shown that certain
molecules that increase in times of stress have also been linked with
several diseases including cancer. Also, evidence of reduced immune
function may help prove the cancer – stress link.
According to the ABC report, Dr. Derek Raghavan said "People in
high-stress occupations, such as police officers, doctors and
firefighters don't have higher incidences of cancer than other members
of the community… Once you have cancer, then the presence of stress and
stress-related states like pessimism and hopelessness are associated
with the progression of cancer and decreased survival." Raghavan is
Director of the Cleveland Clinic Taussig Cancer Center.
Researchers at the Johns Hopkins Kimmel Cancer Center in Baltimore found
that mice exposed to stressful conditions and ultraviolet light
developed skin cancers in less than half the time it took for
non-stressed mice. This research was published in the Journal of the
American Academy of Dermatology.
Generalized anxiety disorder (GAD) affects approximately 3 to 4 percent
of the population, according to Forest Pharmaceuticals. There are many
things people can do to relieve or reduce stress and anxiety. Yoga and
meditation have been shown to reduce stress. Some claim you can reduce
stress by increasing your levels of
implementing relaxation techniques.
