Right chest pain in women is often due to neuromuscular lesions of the right anterior chest wall such as functional lesions, costochondritis, intercostal neuritis, sternal lesions, breast fibroma, breast cysts, mastitis, breast cancer and other disorders, but also common in lung disease, and a small number of cardiac and mediastinal diseases. 1. Neuromuscular lesions of the right anterior chest wall (1) Functional lesions: right chest pain caused by muscle strain of the anterior chest wall due to over-tiredness of the right side of the body, etc. Generally, there is no organic change in the tissue structure. (2) Neuroinflammation such as costochondritis and intercostal neuritis can cause right chest pain in women. (3) Female breast diseases such as breast fibroma, breast cyst, mastitis, breast cancer, etc. are also common causes of right chest pain in women. (4) Sternal lesions such as sternal fracture, sternal tumor, etc. can also have chest pain. (2) Lung diseases: such as lung infection adjacent to the right sternum, pleurisy, lung cancer, etc. can involve the tissue behind the right sternum and cause right-sided chest pain. 3. Heart and mediastinal diseases: such as congenital heart disease accompanied by right ventricular hypertrophy, coronary heart disease, and mediastinal thymoma, etc., which oppress the right post-thoracic tissues and cause right chest pain. Women with right chest pain are advised to go to the hospital for further counseling or treatment.
