Mammary hyperplasia is the most common breast disease in women, and its incidence accounts for the first place of breast diseases. Breast hyperplasia refers to the proliferation of breast epithelium and fibrous tissue, degenerative lesions in the structure of the ducts and lobules of breast tissue and the growth of progressive connective tissue, and its pathogenesis is mainly due to endocrine hormone imbalance. The main manifestations: breast lumps, mostly bilateral multiple lumps, varying in size as nodular or granular, the texture is generally soft or hard, occasionally unilateral single-issue, but mostly accompanied by premenstrual breast distension and pain to touch and pain, and the size of the breast lumps can be cyclical changes with menstruation. In recent years, the incidence of this disease has been rising year by year, the age is also getting younger and younger, mostly in women aged 25 to 45 years old, clinically a lot of non-mammary hyperplasia and misdiagnosed as mammary hyperplasia, first introduced as follows: 1, Breast Cancer The main symptoms manifested as: breast lump, breast pain, or nipple overflow, nipple changes, skin changes, axillary lymph node enlargement, meet this situation to go to a regular hospital to avoid delaying the condition, especially the breast lumps and pain. so as not to delay the condition, especially painless breast lumps, age over 40 years old. 2.Mammary fibroadenoma is mainly a breast lump, single or multiple, tough and solid texture, high activity, the texture is generally tough and solid, there are also multiple, but generally no breast swelling and pain or only mild menstrual breast discomfort, no tenderness, mostly in the age of 30 years old, with the most common in the age of 20 to 25 years old. In addition, on the mammogram, it often shows a round or ovoid shadow with uniform density and its characteristic ring-shaped halo can be an important basis for differential diagnosis. 3, costal chondritis occurs in 20~30 women, most of them consult the doctor with breast pain, and the lesion site is most common in the 2nd and 3rd rib cartilage, and it can also invade the sternal handle, the medial side of clavicle and the anterior and inferior ribs cartilage. The affected rib cartilage feels a dull or sharp pain in the chest, with pressure pain and swelling and elevation, and the pain is aggravated by deep inhalation, coughing or moving the upper limbs on the affected side, and sometimes disperses to the shoulder or the back. Sometimes the pain spreads to the shoulder or back. Even the arm cannot be lifted. However, there is no change in the local skin, and the pain varies in severity, which is often prolonged and affects the patient’s work and study. After the pain disappears, the enlarged rib cartilage can even last for months or years. The main difference with breast hyperplasia is that the pain is relieved when resting or lying on the side, and is aggravated by deep breathing, coughing, lying down, lifting up the chest and fatigue. 4.Intercostal neuralgia Intercostal neuralgia is divided into secondary and primary two kinds, by the thoracic spine degeneration, thoracic spine tuberculosis, thoracic spine injury, thoracic spine sclerospondylitis, tumors, ankylosing spondylitis and other diseases can be secondary to the root of the intercostal neuralgia; ribs, the mediastinum or pleural lesions will be secondary to the dry intercostal neuralgia. It is characterized by pain from back to front, along the corresponding intercostal space radiating in a semicircular shape; pain is stinging or burning pain. The pain is aggravated by coughing, deep breathing or sneezing. The pain occurs on one side of a nerve, physical examination found that the thoracic vertebral spinous process and the intercostal space has obvious pressure pain; typical radicular intercostal neuralgia patients, flexion test is positive; the distribution area of the affected nerve is often sensory hypersensitivity or hyperalgesia and other neurological damage manifestations. 5, thoracic intramuscular fasciitis, mostly trauma or excessive stretching history, the performance of the chest diffuse pain, mostly before the main, more severe pain, can affect the movement and sleep point pressure pain and subcutaneous nodules, patients can point out their pain points; pressure in addition to local pain, but also along the distribution of the pain point of the nerve endings conduction, reflex appear in the neighboring parts of the place pain, and sometimes in the pain point of the nodular hardness can be touched. The cervical vertebrae and both upper limbs are affected by the sensation of movement. Because myofasciitis restricts the contraction and relaxation of the deep muscles, when the cervical spine and both upper limbs are moved, the patient has the stiffness of being pulled or the pain is aggravated.
