It is more likely to be mammary gland hyperplasia, but it may also be mammary gland fibroadenoma or lipoma or malignant tumor of the breast, which is not easily distinguishable by palpation. If you have the above symptoms, go to a breast specialist for an ultrasound examination of the breast as soon as possible. If it is breast hyperplasia, you need to regulate your emotions and life pattern, avoid staying up late at night and have regular reviews. If it is considered to be a breast fibroadenoma, surgery is needed according to the situation, which is minimally invasive, less traumatic and quicker to recover, so don’t worry too much. If it is a lipoma, it does not need to be treated, but only needs to be followed up regularly. If the lipoma continues to grow within a short period of time or is large in size and affects the appearance, it needs to be considered for surgical removal. If it is considered as malignant tumor of breast, radical surgery of breast tumor is needed.
