One study found a link between meat and the development of breast cancer. Red meat, processed meat intake was a risk factor for breast cancer development, while poultry, fish, eggs, milk, nuts and legume protein intake instead led to a lower risk of breast cancer, with a greater role for legumes, lean meats and milk in particular. Therefore, chicken, fish, eggs, milk and beans are the preferred sources of protein for breast cancer patients who are protein deficient.
