Breast swelling and pain are mostly considered to be related to breast hyperplasia, and can be diagnosed through breast ultrasound or mammography. Therefore, patients with breast hyperplasia need to eat less food containing estrogen, as supplementing exogenous estrogen has been confirmed to increase the incidence of breast cancer, and it is also advised to reduce the intake of fatty and high-calorie diets. Most epidemiological studies confirm that weight gain is associated with breast cancer, especially weight gain after menopause should be paired with reduced alcohol consumption. Reports indicate that drinking may increase hormone levels in the body, leading to an increased risk of breast cancer in women. It is suggested to consume more foods rich in fiber and vitamins. Although the mechanism is not yet clear, fiber has been confirmed to have an inhibitory effect on both breast cancer and colorectal cancer, and research suggests that vitamin A also has a protective role in breast cells.
