Papaya has no effect on breast enlargement because female breast development is mainly influenced by genetics, exercise and nutritional status and hormone levels. Some women think that breast development is not good, and it is related to heredity and usually cannot be changed. Proper exercise for the breasts, such as pectoralis major muscle exercises, while ensuring adequate nutrition will result in relatively better fat synthesis, which is also helpful for mammary gland development. Hormones can also have an impact on female breast development, female breasts may swell before menstruation, due to hormone levels, estrogen can promote breast tissue proliferation and fat formation, so in the clinic the doctor will apply estrogen to stimulate female patients to proliferate the mammary gland. However, regular monitoring and review are required when using the drug. If estrogen is used in excess, it may cause other problems.
