In fact, many diseases cannot be completely cured, including the common cold, for which there is currently no way to completely eradicate it, meaning there isn't a medicine that, once taken, prevents one from ever catching a cold again. Of course, this has a lot to do with the mutations of the cold virus. However, pectus excavatum can be cured, and there are generally two methods of treatment for it: surgical and non-surgical. The surgical method is suitable for older patients with harder bones. Conservative treatment is appropriate for younger patients with more elastic rib cages, who can cooperate well, or whose family can supervise and support them through this non-surgical approach. Regardless, it is completely possible to cure pectus excavatum, and there are methods to do so.
