Smoking cigarettes is a bad habit that can attack the people’s health. But more harmful is when smokers smoke two or more packs per day. A previous study showed that women who used to smoke two or three packs per day may increase their risk of having breast cancer.

The only escapes from having breast cancer are linked to every day exercises, reducing alcohol intake, and preventing postmenopausal obesity, according to previous studies.

But the current research affords new findings that a woman who smoke can limit her risk of having breast cancer by quitting smoking.

A group of anti-smoking researchers investigated and compared smoking history and other factors which can cause breast cancer among 1,225 women who had breast cancer and 6,872 who did not during the first year after their first visit to the Mayo Clinic Breast Clinic.

From all investigated women, just over 10 percent were current smokers, approximately 9 percent were ex-smokers, and 81 percent were non-smoker.

Additional to the connection with smoking, researchers found that women who had consumed oral contraceptives for 11 years or more had an almost 200 percent increase in the occasion of having breast cancer. But women who consumed postmenopausal hormone treatment showed 81 percent increased odds, in the meantime aging also rose the occasion of developing breast cancer by 2 percent yearly.

At the end of investigations, researchers also found that women that had a hysterectomy, decreased odds by 35 percent. In addition, they also did not observed a compounding increase in breast cancer risk among women with more than one risk factor.

Previous studies with contrary findings concerning smoking and breast cancer risk increase did not successively characterized smoking as current, former or never. But this fresh study defines anybody who had a long history of smoking.

Researchers concluded that their goal was to evaluate how pre- and post-menopausal duration of smoking, quantity of cigarettes smoked, and exposures to secondhand cigarettes smoke could change a woman's occasion of having breast cancer.
