If there is a noticeable hard lump in the breast, and gradually can become softer, it is considered to be a sign of localized improvement of the condition, which can also be said to be a good thing. It is usually a hard lump formed by breast hyperplasia, which is regulated by changes in hormone levels in the body, especially in the pre-menstrual period, due to the increased levels of estrogen and progesterone, which can also lead to breast follicles or local soft tissue edema. The patient may also experience swelling and pain in the breasts, and may even be accompanied by insomnia and other uncomfortable symptoms. After the menstrual period, the lumps can gradually decrease and disappear or become softer, so it is also related to hormonal changes. For patients with breast hyperplasia, the hard lumps can gradually become softer after treatment with medication, which is often in the form of proprietary Chinese medicines. Therefore, medication is needed if necessary, and regular checkups are also needed.
