Grilled, Barbecued Meat Risky for Breast Cancer Survivors

Grilled, Barbecued Meat Risky for Breast Cancer Survivors

Previous studies have linked a high consumption of grilled, barbecued, or smoked meats with an increased risk of breast cancer. Now, a new study finds that it may also increase the risk of all-cause mortality for women who have survived the disease.
Study co-author Humberto Parada, Jr., of the University of North Carolina at Chapel Hill, and colleagues recently reported their findings in the Journal of the National Cancer Institute.
After skin cancer, breast cancer is the most common cancer among women in the United States. This year, it is estimated that around 252,710 new cases will be diagnosed in the US, and more than 40,000 women will die from the disease.
According to the American Cancer Society, there are currently more than 2.8 million  breast cancer survivors in the US, medicalnewstoday.com reported.
The new study, however, suggests that the lifespan of women who have survived breast cancer may be cut short by eating high amounts of grilled, barbecued, or smoked meats.
The National Cancer Institute (NCI) says this is because such cooking methods can lead to the production of polycyclic aromatic hydrocarbons and heterocyclic amines, which are chemicals that can trigger changes to the DNA that increase cancer risk.
Parada and colleagues note that while many studies have linked meats cooked at a high temperature to a higher risk of breast cancer, no studies have looked at whether the intake of such meats affects survival after breast cancer.
To address this gap, the team interviewed 1,508 women who had received a diagnosis of first primary invasive or in situ breast cancer in 1996 or 1997.
At study baseline, all participants were asked about their consumption of four different types of grilled, barbecued, and smoked meats in each decade of life. Five years later, the women were asked about their intake of these meats during the intervening 5 years.
Over a median 17.6 years of follow-up, 597 of the women died. Of these deaths, 237 (39.5%) were associated with breast cancer.
Overall, compared with women who reported a low intake of grilled, barbecued, or smoked meats prior to a breast cancer diagnosis, those who reported a high intake of these meats were found to be at a 23% greater risk of mortality.
Women who reported a high intake of smoked meat were at 17% increased risk of all-cause mortality and a 23% increased risk of breast cancer-specific mortality, compared with those who reported a low intake.
Compared with women who consumed low amounts of grilled, barbecued, and smoked meats prior to or after a breast cancer diagnosis, those who reported a continued high intake were at a 31% increased risk of all-cause mortality, researchers report.
Based on their findings, Parada and colleagues conclude: “High intake of grilled/barbecued and smoked meat may increase mortality after breast cancer.”
