Smoking greatly increases the risk of breast abscesses, painful inflammatory lesions that are difficult to treat and tend to recur at rates as high as 40% to 50%, a new study has found.
The University of Iowa study was also one of the first to show evidence that nipple piercing is a risk factor for breast abscesses, with the development of abscesses occurring up to seven years after the piercing.
Other major risk factors for the condition include obesity and diabetes, the researchers noted.
Study results
In the study, published in the Journal of the American College of Surgeons, researchers looked at data from 68 breast abscess patients, including 43 who were smokers and nine who had had a nipple piercing. None of the women had a history of breast cancer, breast radiation therapy or breast surgery within the previous 12 months.
Compared with non-smokers, smokers were six times more likely to develop breast abscesses, the investigators found. And the condition was 15 times more likely to recur in smokers than non-smokers, the researchers noted.
"Nearly 60% of patients with a recurrence of breast abscess were heavy smokers," Dr Vinod Gollapalli, a post-doctoral fellow in the surgery department at the University of Iowa Carver College of Medicine in Iowa City, US, said in a journal news release. "Since smoking appears to be a strong risk factor for both causing breast abscess and its recurrence, we recommend patients should be counselled to quit smoking as an integral part of treatment." - (August 2010)
