The mammary glands contain fatty tissue but not entirely fat, and the amount of fat in the mammary glands varies with age. In young women, the mammary glands contain a small amount of fat tissue under the skin, and the entire mammary gland is made up of several lobes. The mammary tissue is connective tissue, so young women’s mammary glands are tougher to the touch. As the fat content in the mammary glands increases with age, most of the glandular tissue of the mammary glands in older women will be replaced by fat, so most of the mammary glands in older women are composed of fat tissue. It is softer to palpate the ligaments will also be loose and there will be significant sagging of the mammary glands. The subcutaneous fat content is different, and the adipose tissue of the mammary glands is also different. Try to pay attention to more sports and exercise, and lose weight to help maintain the normal shape of the mammary glands and avoid sagging. Usually pay attention to wear appropriate underwear, if there are obvious symptoms of discomfort, try to go to the regular hospital.
