A lump inside the breast is very common, and many patients have it as a result of breast enlargement, forming a hyperplastic nodule, or a hyperplastic mass, and the patient also presents with pain. In addition, bumps that occur in the breast, or tumors, or occupational disease, may also be malignant, especially if there is a significant family history or high-risk factors, and may manifest as irregularly bordered bumps. For malignant tumors of breast, surgery should be actively chosen. Depending on the needs of the disease and the patient’s will, radical excision with breast preservation or traditional modified radical excision surgery can be chosen.
