Finding a small nodule in the breast is not something to be overly concerned about. The first step is to perform a color ultrasound of the breast for further screening and identification. It is common to see benign nodules, and usually the patient will also have regular breast swelling and pain, which is more likely to be mastopexy nodules, for example, usually the ultrasound examination will also show regular margins, as well as a uniform density of the mass, which can be followed up and observed regularly. If you have painful symptoms, you can take oral Chinese medicine such as breast fetish elimination tablets for treatment. For nodules with irregular margins, surgical excision can be chosen for pathological examination if necessary. For malignant nodules, radical excision should be performed, but regular checkups, including color ultrasound, tumor markers and CT, are required after surgery. Breast nodules also occur very frequently, and malignant nodules have a tendency to run in families.
