Suffering a major loss, such as the death of a loved one, may play a
role in how likely people are to develop cancer or how quickly people
with cancer succumb to their illness, according to a new study.
Researchers looked at the impact on parental health that resulted from
the death of a son due to war or an accident.
-
The researchers focused on over 6,000 parents living in Israel, approximately
two thirds of whom lost one or two sons in the Yom Kippur War and
its aftermath, between 1973 and 1974.
-
The remaining parents had sustained the loss of one or two sons in
accidents between 1970 and 1977.
-
With all parents, regardless of the cause of their son's death, there
was a significant increase in their risk of developing certain cancers
after the loss, including lymphatic tumors and melanomas.
- An increased risk of the development of respiratory tumors was found
solely among mothers and fathers who lost a child in an accident.
The authors conclude that while there is an association between stress
and the onset and progression of cancer, the speed with which the parents
ultimately died from cancer after their loss was only accelerated if their
cancer had been diagnosed prior to their son's death and not after the
fact.
In an interview with Reuters Health, Dr. Levav emphasized that the overall
message is that human beings should not be thought of as a sum of their
parts but rather as whole individuals with physical and mental components
interacting and affecting one another.
"That perhaps is the most interesting idea that this study emphasizes -- that
people are one single entity," he said. "You can't split them
up into separate spheres -- one for emotions and one for biology."
