One serving a day increment in red meat intake during adolescence was associated with a 22% higher risk of premenopausal breast cancer and each serving per day increment during adulthood was associated with a 13th higher risk of breast cancer overall. Those that ate more poultry during the same period had a lower risk of developing breast cancer.
Most of the studies done prior found no direct link between red meat and cancer. They usually measured the diet of women during their midlife or later, not during early adulthood, which is when mammary glands are more susceptible to carcinogenic exposures.
In many cases, you may inherit DNA mutations that can dramatically increase the risk of developing certain cancers, which you can’t escape. Doctors and nutritionists recommend a healthier lifestyle, by kicking habits like smoking and alcoholic drinks, as well as eating more fruits and vegetables that can prevent cancer. It is recommended that you decrease the amount of red meat you eat per day, instead of having it daily, you should just have it once a week to decrease the risk of developing breast cancer.
