Breast lumps are a common disease in women. Many types of breast diseases can be characterized by lumps in the breast. Some breast lumps are accompanied by obvious pain, and some lumps are not painful or itchy. Because painless breast lumps are just one of the characteristics of breast cancer, experts advise that the more painless breast lumps, the more attention should be paid. Which breast lumps are painful? 1, breast hyperplasia: masses can occur in the unilateral or bilateral breast, single or multiple, occur in the upper quadrant of the breast. The borders of the mass are not obvious, the texture is medium or slightly hard and tough, the activity is good, there is no adhesion with the surrounding tissue, and often tenderness. Breast lumps also have characteristics that change with the menstrual cycle. Before the menstrual mass, the mass enlarges and hardens, and the mass shrinks and becomes soft after menstruation. The pain is mainly at the breast lumps, often pain or tingling. 2, mastitis: Inflammatory breast lumps, often accompanied by more severe breast pain, lumps also accompanied by obvious red, swollen, heat, pain and other inflammatory reactions, the mass can purulent ulceration, after anti-inflammatory treatment plus After local drainage, the inflammation subsides and the mass disappears. Which breast lumps do not hurt? 1, breast fibroadenoma: occur in young women, the most important clinical manifestation is breast lumps, and in most cases, breast lumps is the only symptom of the disease. Most of the patients are inadvertently discovered, generally do not have pain, and do not change with the menstrual cycle. The mass happens in the outer quadrant of the breast. Often single, but also multiple. Round or oval. Smooth surface, tough texture, clear boundary, no adhesion to the skin and surrounding tissues, large activity, and a sense of sliding. 2. Breast cancer: The breast lumps of early breast cancer usually have no obvious pain and discomfort, and they are often found to be very large. Only when the skin is ulcerated and infiltrated in the late stage, can the pain occur. Cancerous masses are often progressively enlarged, with features such as solitary, hard, and poor activity. Supplementary reading: The correct way to self-test breast lumps Regular self-examination is an important measure for early detection of breast lumps. The self-examination of breast lumps should pay attention to the following points: 1, check the time: the best check once a month, time is better after a week after the passage of time, check in the bath is more convenient. 2. Examine the bilateral breasts with both hands (left hand to right side and right hand to left side). 3, the other four fingers outside the thumb close together, close to the chest wall, alternating light pressure by the fingers, in order to touch the entire area of ​​the breast. Normal breasts are softer, and there is something to feel slipping under your finger when there is a lump. 4, avoid grasping the breast by hand, because the grasp will make the normal breast tissue shrink into a group, it feels like a lump, even if there is a real lump can not find out.
