You might think that smokers are not at risk of developing breast cancer because they don’t smoke.
In fact, they are.
They may not even be at risk if they do, however, because they have a very low risk of getting breast cancer.
That is the finding of a new study in the New England Journal of Medicine.
The study looked at the risk of lung cancer in women who were both former smokers and current smokers and the risk for lung cancer among those who never smoked.
For women who never had smoked, the researchers found a 1 in 10 chance of developing lung cancer.
For men, the risk was 1 in 2,000.
Women who never smoke and women who smoked were different.
Both groups had a higher risk of the disease.
The risk of smoking increased significantly for women who had never smoked and for men who never started smoking.
For those who had smoked for more than 10 years, the odds of developing cancer increased 1.6-fold, the study found.
In addition, women who ever smoked had a 1.7-fold higher risk for developing cancer.
The researchers said the study provides more evidence that people who are already smokers are at a higher rate of lung cancers.
But there are other factors at play, too.
It is not clear if the women in the study had some underlying genetic vulnerability to the disease or whether there are environmental factors that could have affected their development.
The findings add to growing evidence that smoking can increase the risk or even cause cancers in women, particularly in people with a genetic vulnerability.
In a separate study published earlier this year, the National Cancer Institute reported that women with a family history of breast or ovarian cancer had a 40% increased risk of their disease developing.
Researchers at the Johns Hopkins University School of Medicine in Baltimore found that women who have had two or more breast or ovary cancers were 20% more likely to develop cancer.
Some experts say it is not just women who are at risk.
“There’s also evidence that men are at higher risk,” said Dr. Paul S. Ewing, director of the National Institute on Drug Abuse (NIDA), the agency responsible for regulating drug and alcohol use.
He said some women are especially vulnerable.
“It’s a very complicated issue,” he said.
But some experts are taking the latest research into account.
“This is a very interesting study, and it adds a lot of interesting information to the debate,” said Nancy O’Malley, director and chief medical officer of the Women’s Health Initiative, a Washington-based advocacy group for women’s health.
“What we want to know is, how much of that is attributable to genetics?
If it is, then maybe we can have better targeted strategies to help women in our communities, especially in places where they are at high risk.”
But other experts are not so optimistic.
“I don’t see this as evidence that cigarettes cause breast cancer,” said Thomas C. Pimentel, a cancer epidemiologist at the National Institutes of Health (NIH).
“It is the opposite.
Cigarette smoke does not cause breast cancers.
Cigarettes are a form of cancer, and if we can identify the cells that are growing in the lungs of smokers, we can target them with medicines.”
“I think this is a good first step, but I’m not sure it’s sufficient,” said William A. Bresnahan, a professor of preventive medicine at Stanford University and the director of Stanford Center for Tobacco Control Research.
“You can’t get the smoking-caused effect out of the body.
And if we don’t have that smoking-induced effect in the body, then we can’t say, ‘Hey, you don’t need cigarettes.'”
He said there are also many other things that contribute to the risk.
For example, alcohol and tobacco smoke can cause liver damage.
Smoking may increase the chances of developing heart disease, diabetes, hypertension, and depression.
And women who smoke may be more susceptible to the side effects of certain medicines, including some antidepressants and some drugs for treating asthma and diabetes.
But Dr. Pimentsons opinion is that most of the evidence so far points to a small amount of exposure to the harmful substances that cause cancer.
“When you take a cigarette, you get the nicotine, and the amount of nicotine you get from a cigarette is small,” he explained.
So this is all anecdotal, but that is the evidence.” “
But if you don`t smoke, the same amount of cancer risk goes away.
So this is all anecdotal, but that is the evidence.”
He said he hopes the research will help people decide whether or not to quit.
“If people can stop smoking, and then they are more successful at quitting, then it may be the combination of the smoking cessation program, the medications that they are taking, and a low intake of tobacco that actually keeps them off tobacco,” he told CBS News.
