WEDNESDAY, Aug. 6, 2014 (HealthDay News) -- Almost 10 percent of people who survive cancer are still smoking a decade later, a new study from the American Cancer Society shows.
Experts said the findings, reported online Aug. 6 in the journal Cancer Epidemiology, Biomarkers and Prevention, show that some cancer survivors need ongoing help with kicking the smoking habit.
The study also underscores how tough it can be to quit tobacco, said Dr. Norman Edelman, senior medical advisor to the American Lung Association.
"Am I surprised by the findings? No," said Edelman, who was not involved in the study. "It's consistent with what I've seen in clinical practice. With cancer survivors, one of the problems we have is convincing them there's a point [to quitting]."
Yet it's clear there is a point, Edelman said, since kicking the habit may lower the odds of not only a cancer recurrence, but also such killers as emphysema and heart disease.
"Smoking can kill you in a lot of ways," Edelman said.
The new findings are based on nearly 3,000 U.S. adults taking part in a long-term study of cancer survivors.
"We really haven't known what happens [to smoking habits] years after a person's cancer diagnosis," said lead researcher Lee Westmaas, director of tobacco control research at the cancer society.
His team found that over 9 percent of cancer survivors were smoking almost a decade after their diagnosis.
"And they were smoking pretty heavily," Westmaas said. Current smokers averaged 15 cigarettes a day, though 40 percent smoked more than that.
What's more, people who had survived lung or bladder cancers -- two cancers closely linked to tobacco -- had the highest rates of current smoking (at 15 percent and 17 percent, resp
