Many patients with scarring have recurrent episodes of the condition and often do not achieve good results with scar injections, so most of the general treatment for scarring is a combination of surgical excision with adjuvant treatment such as radiotherapy. Many patients ask why radiotherapy is needed and what effect it has on the body. In theory, the radiation therapy used to treat scars is harmless to the human body. First, the dose of radiation therapy used is small, only about one-third of the radiation dose used to treat cancer, so the dose is not very large and the damage to the body is much less. Secondly, the depth of radiation we use is shallow. When we treat scars, the plane of radiotherapy is at this layer of skin, and the radiation dose detected at 1.5 cm below the radiation plane is only about 1% of the set dose. Therefore, as long as the scope and depth are controlled well, radiation done on the skin will not affect the deep lungs, liver and other organs. However, some parts are not suitable for radiotherapy, such as breast tissue (chest), thyroid tissue (neck) and other glandular surfaces, because glandular tissue is sensitive to radiation and should avoid high-energy radiation stimulation as much as possible to prevent the occurrence of lesions. This may affect the growth of the child’s bones. The use of radiotherapy and other combined treatment methods, in addition to removing the lesions at once, also greatly reduces the recurrence rate and high patient satisfaction, so don’t worry too much and trust your doctor, you can definitely cure the disease.
