Mammary hyperplasia nodule refers to a type of lesion in the breast, while solid nodule refers to a breast nodule that is solid in nature. Mammary hyperplasia nodule refers to the abnormal proliferation of breast hyperplasia localized, the size is not uniform, and finally the formation of nodular changes, manifested as a flocculent, flaky lump nodule in the breast, the growth trend is slow. They are usually soft and painful, with clear boundaries and a certain degree of mobility, and the pressure and pain will be significantly increased before menstruation, and will also be affected by emotional changes. Solid breast nodule is shown under ultrasound, usually a single nodule, and nodule mobility, no pressure and pain, will not be affected by the menstrual period. A solid breast nodule, on the other hand, is a breast nodule that is solid in nature. It is a description of the nature of the nodule and is not diagnostic. Patients with breast nodules and solid nodules are advised to live a light diet, maintain a good psychological state and go to the hospital regularly to review the status of the nodules.
