Typical symptoms of breast cancer

Breast cancer usually occurs in breast glandular epithelial tissue and is one of the most common malignant tumors in women. Its typical manifestations are mainly the following:

1. Painless lumps: Painless lumps appear in the early stage. When breast cancer is combined with cystic hyperplasia, there may be distending pain and dull pain. Pain in late-stage breast cancer often indicates that the tumor directly invades the nerves. Most of them are single, and rarely multiple. The shape is round, oval or irregular. The texture is generally hard and the boundary is unclear. Some, such as medullary carcinoma, have a soft texture and clear boundaries. They often occur in the upper outer quadrant, the lumps grow rapidly, and there may be mobility in the early stage.

2. Changes in the nipple and areola: Breast cancer in the central area of ​​the breast can cause the large ducts to be invaded, which can cause the nipple to become flat, sunken, or retracted, or even sink under the areola, causing the areola to deform. Paget's disease can cause eczema-like changes in the nipple and areola skin.

3. Skin changes: Common symptoms include superficial venous distention, dimples and orange peel-like skin. Inflammatory breast cancer patients may have large areas of darkened skin on their chests, hardened and thickened, with cancerous plaques and ulcers forming an armor-like chest wall. Advanced breast cancer may break out superficially, forming ulcers or cauliflower-like neoplasms.

4. Nipple discharge: Breast cancer with discharge is more common in intraductal carcinoma and papillary carcinoma. Bloody discharge is more common, followed by serous, serous-bloody, and watery discharge. Breast cancer with discharge as the only symptom is extremely rare, and most of them are early intraductal carcinoma and papillary carcinoma. Most breast cancers with discharge are accompanied by discharge after the lump is found.
