People with hyperplasia of mammary glands can eat bamboo shoots. Foods rich in cellulose and vitamins can be consumed more often, although their mechanisms are not yet clear. However, it has been confirmed that cellulose can inhibit both breast cancer and colon cancer. Vitamin A also plays a role in protecting the mammary glands. It is advisable to reduce the intake of fats and high-calorie diets. Most epidemiological studies show that weight gain is associated with breast cancer, especially after menopause. Alcohol consumption should be limited as it is reported that it may increase estrogen levels in the body, leading to an increased risk of breast cancer in women. Regular breast ultrasound and mammography are needed for fibrocystic breast disease.
