This reference extract addresses Breast mass, a related subject. It does not cover every part of Breast lumps.. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
A breast mass, also known as a breast lump, is a localized swelling that feels different from the surrounding tissue. Breast pain, nipple discharge, or skin changes may be present. Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue.
Causes include fibrocystic change, fibroadenomas, breast infection, galactoceles, and breast cancer. Breast cancer makes up about 10% of breast masses. Diagnosis is typically by examination, medical imaging, and tissue biopsy. Tissue biopsy is often by fine needle aspiration biopsy. Repeated examination may be required.
Treatment depends on the underlying cause. It may vary from simple pain medication to surgical removal. Some causes may resolve without treatment. Breast masses are relatively common. It is the most common breast complaint with the women's concern generally being that of cancer.
How this connects to General Surgery
Molecular investigation links DNA variation and gene regulation to RNA, proteins and cellular function. Assays measure selected molecular features with finite sensitivity and specificity; a detected variant or transcript does not automatically establish biological causation or a clinical diagnosis.

What the underlying subject studies
Surgery concerns anatomical conditions for which operative and nonoperative strategies may be considered. Understand the region, potential pathology, tissue blood supply, wound response and overall patient health before thinking about procedures.
How mechanisms and evidence connect
The perioperative period includes assessment, informed consent, infection prevention, physiological support, operative planning, recovery and follow-up. Technical procedures depend on specialist training and case-specific risk.
How to develop a sound explanation
Use a sequence diagram to connect indication, anatomy, pathophysiology and anticipated complications. A conceptual figure here is not a guide to performing an operation or managing an emergency.
