Most Men Over 40 Take Steps to Try to Prevent Prostate Cancer, Jefferson Medical College Survey Shows
A new survey by researchers at Jefferson’s Kimmel Cancer Center shows that most men over 40 attempt to protect themselves
against prostate cancer. The steps they take range from prostate cancer screening to exercising, taking supplements and stopping
smoking.
“Surprisingly, when asked, most men say they are doing something to protect themselves,” says Ronald E. Myers, Ph.D., professor
of medicine at Jefferson Medical College of Thomas Jefferson University in Philadelphia. “The presumption is, most men don’t
think about prostate cancer until they have problems, and if they do think about it, they don’t do anything. These results
indicate that this doesn’t seem to be the case.”
The researchers also found that men who said they had been screened were more likely to be more highly educated, better off
financially, and believed that screening was an effective and convenient tool to prevent prostate cancer.
“This the first time anyone has reported what men do to protect themselves against prostate cancer,” says senior author Elisabeth
Kunkel, M.D., professor and vice chair for Clinical Affairs in the Department of Psychiatry and Human Behavior at Jefferson
Medical College of Thomas Jefferson University.
Drs. Kunkel, Myers and their co-workers at Jefferson’s Kimmel Cancer Center report their findings in the current issue of
the journal
Cancer Epidemiology, Biomarkers and Prevention.
Prostate cancer screening is controversial. Prostate cancer tends to grow slowly, and debate centers on whether or not early
detection and treatment do more harm than good. It is also unclear if so-called preventive methods such as diet, exercise
and supplements such as selenium actually help prevent prostate cancer.
The researchers wanted to know what men do – if anything – to protect themselves from developing prostate cancer. The team
surveyed two groups of men by either phone or mail and combined their data. In the study, 441 men were asked if they were
taking any steps to protect themselves against prostate cancer, and what those steps were. In addition, they were asked if
they had had screening – a prostate specific antigen, or PSA, test and/or a digital rectal exam – in the past year. Their
responses were classified into three categories: conventional care, such as screening; self-care, which includes watching
diet, getting regular exercise, taking nutritional supplements; and doing nothing regarding prevention.
According to the survey, says Dr. Myers, “Whether or not men take protective action seems to be influenced by socioeconomic
status and their perceptions about screening – whether they think taking certain actions is worth it and is convenient. The
decision to take protective action is also influenced by their perception of their risk.
“Most men we describe as engaging in conventional care are more educated, and they believe screening is effective and easy
to do,” Dr. Myers says. Conventional care users tend to be better off socioeconomically and look for ways to protect themselves
from disease, he says. “Men who do self-care seem to be less advantaged socioeconomically, are not very concerned about prostate
cancer and screening, and think less about protective behavior.”
Twenty percent of those questioned said they didn’t take any steps to prevent prostate cancer.
Men were more likely to do self-care if they were less worried and concerned about prostate cancer – a surprising result,
says Dr. Kunkel. “Clinically, that hasn’t been our experience,” she says. “We’ve found that the more worried and concerned
men are, the more likely they are to use non-conventional practices.”
“It is the first time prostate cancer behaviors have been categorized in this way,” says Dr. Kunkel. “People have looked at
screening behavior, but no one has looked at the use of self-care to protect yourself against prostate cancer, whether that
is really protective or not.”
Dr. Myers agrees. This survey, he says, “is a more comprehensive look at protective behavior. It’s the first paper to ask
the question about how men protect themselves against disease and to put forward some ideas as to why men make different choices.”
In one of the studies, the participants were African-American men between 40 and 69 who were seen in three primary care practices
in Philadelphia. African-American men have a higher risk for prostate cancer than other groups. In the other study, the subjects
included both white and non-white men between ages 50 and 69 who were seen at a university-based internal medicine practice
in Philadelphia. In both surveys, participants saw their primary care doctor in the past two years and had no known problems
with their prostate gland. They didn’t have a history of cancer or benign prostate disease. They had never had a prostate
biopsy or ultrasound.
Dr. Kunkel says, “we need to learn more in terms of both white and non-white men who decide to use different protection strategies,
and what in terms of sociodemographic, cognitive and social support factors affect screening behaviors.
“We would like a better understanding of the behaviors in terms of teasing out whether they do these behaviors as part of
a general lifestyle or whether these behaviors are specifically to protect themselves against prostate cancer,” she says.
Next, the researchers will investigate “how the role of the physician interfaces with this behavior in terms of what suggestions
physicians make that influence decision-making.”
Future studies should examine larger, more geographically diverse populations of men, she notes.
