When many people are not sure what breast tumor disease is, they tend to confuse breast enlargement with breast tumor disease. Today, we are going to organize some related knowledge to understand it! First of all, mastocytosis is also called mammary adenopathy, which is a kind of benign hyperplasia of breast tissue, and when it comes to benign, the possibility of cure is very high. It is not a tumor, but also not an inflammatory disease, and not a cancer. That is to say, breast hyperplasia is not as serious as breast tumor, but it is not simply an inflammatory disease either. Therefore, patients with mastocytosis should be treated promptly. According to statistics, fifty percent of women over the age of thirty will have different degrees of hyperplasia. So what is the cause of breast enlargement? It is because the endocrine system within the ovaries of women is disrupted and estrogen is elevated. This can lead to breast enlargement. However, under normal circumstances, the breast tissues of women also have periodic enlargement, but with the periodic adjustment of hormones, the enlargement problem will also appear to be alleviated and recovered. However, in some women with endocrine disorders, there will be no recovery from the hyperplasia and it will lead to mastopexy. Generally, mastocytosis occurs in women between the ages of 30 and 50. Adolescent girls may also experience slight swelling and pain in their developing state, which is normal. It is also important to understand that ninety percent of breast enlargement is safe. However, if it becomes a tumor, then it means that cancer has occurred, and it will be relatively difficult to treat the patient at this time. The early symptoms of cancer can be found in the early stages of the disease, and there is a possibility of recurrence of breast cancer after surgical removal. In case of recurrence, the situation will be very bad and there is a high risk of losing one’s life. But what are the common clinical manifestations and diseases of breast problems? How should I do a breast self-examination? The following are some of the breast self-examinations for women to use. The clinical manifestations of breast problems are: lumps, pain, nipple overflow, breast skin changes, nipple changes, and breast shape changes. Among them, the first three clinical manifestations are the most frequent. In terms of the number of incidences most of them are breast hyperplasia, benign diseases such as: mastocytosis, breast fibroids, ductal dilatation, etc. Breast health care can be divided into self-care and regular examination by professional physicians. Self-diagnosis method of breast cancer: The best time for self-examination is one week after the end of menstruation, or if the menstrual cycle is irregular, it is better to perform self-examination at the same time of the month. Visual examination, compare whether the bilateral breasts are symmetrical, and pay attention to any size and abnormal changes in appearance. Abnormal signs include: nipple overflow, nipple retraction, skin wrinkling, dimple sign, skin flaking, and abnormal changes in breast contour. For palpation, use the index, middle and ring fingers to slowly, steadily and carefully touch the breast, moving it gradually in a downward or reverse direction, at least three times from the periphery of the breast to the nipple. Care should be taken not to miss any part. At the same time, the axillary lymph nodes should be checked for enlargement. Finally, the nipple is gently squeezed with the thumb and index finger to observe whether there is nipple drainage. In terms of prevention: first of all, attention should be paid to a balanced diet: proper control of fat and animal protein intake, strengthening physical exercise, and reducing the occurrence of obesity. Eat less or not eat foods containing high estrogen in plant and animal foods, such as: vitamin e, soy isoflavones and other health products; second, breastfeeding: breastfeed babies as much as possible and try to avoid the use of estrogen, especially for menopausal women. Third, avoid radiation: reduce unnecessary radiation exposure. Fourth, treat benign lesions: actively treat benign lesions of the breast. Fifth, learn self-examination: all women over 40 years old should learn self-examination methods, and women over 45 years old with risk factors should pay more attention to self-examination. Finally, we warmly remind our female friends must give more attention to their breasts, often self-examine or go to regular professional oncology hospitals for some professional examinations, and gradually suggest to improve their life time and unhealthy lifestyle and so on.
