Many keep smoking even after cancer diagnosis

Washington: A large number of people, believe it or not, continue to
puff away merrily even after being diagnosed with lung and
colorectal (large intestine) cancer.
Putting a halt to smoking after a cancer diagnosis is important
because it can negatively affect patients' responses to
treatments, their subsequent cancer risk and, potentially, their
survival.
Elyse R. Park from the Massachusetts General Hospital - Harvard
Medical School in Boston led a team that looked to see how many
patients quit smoking around the time of a cancer diagnosis, and
which smokers were most likely to quit.
The investigators determined smoking rates around the time of
diagnosis and five months after diagnosis in 5,338 lung and
colorectal cancer patients, the journal Cancer reports.
At diagnosis, 39 percent of lung cancer patients and 14 percent of
colorectal cancer patients were smoking. Five months later, 14
percent of lung cancer patients and nine percent of colorectal
cancer patients were still smoking, according to a Harvard
statement.
These results indicate that a substantial minority of cancer
patients continue to smoke after being diagnosed. Also, although
lung cancer patients have higher rates of smoking at diagnosis and
following diagnosis, colorectal cancer patients are less likely to
quit smoking following diagnosis.
Colorectal cancer patients who continued to smoke tended to be
male, completed less education, uninsured, not have had surgery,
and once smoked a high number of cigarettes per day.
"These findings can help cancer clinicians identify patients who
are at risk for smoking and guide tobacco counselling treatment
development for cancer patients," said Park.
