Breast hyperplasia worsening can turn into breast cancer. The texture of breast cancer lumps is generally quite hard, and some are as hard as stone. They mostly occur as a single lump on one side, and can be round, oval, or irregular in shape. They can grow quite large, have limited mobility, and easily adhere to the skin and surrounding tissues. The lump is unrelated to menstrual cycles and emotional changes, and can rapidly increase in size over a short period of time, commonly occurring in middle-aged and older women. Additionally, on a mammogram, breast cancer often appears as a lump shadow, with small calcification spots, abnormal vascular shadows, and spurs also aiding in diagnosis. However, the final diagnosis must be confirmed by histopathological examination results.
