Uterine cysts are supposed to be a misnomer for cervical cysts. The uterus itself hardly grows cysts, and in rare cases uterine fibroids may become cystic. Uterine cysts are usually referred to as cervical cysts, also known as cervical nuchal cysts, or nuchal cysts for short, which are caused by chronic inflammation of the cervix and do not become cancerous under normal circumstances, but if left untreated and if the cervix is also infected with human papilloma virus, it may still become cancerous, but the chances are lower. Therefore, the chances of cancerous cysts in the uterus vary from person to person. Cysts on the cervix are mainly caused by chronic inflammation and long-term stimulation, resulting in obstruction of the glandular ducts and inability to discharge secretions, forming cysts, so it is not caused by malignant lesions of cervical tissue cells. In this case, if treated in time, there is no possibility of cancer. After the formation of cysts in the uterine cavity, they actually do not have great influence and harm to human body and will not affect fertility, so regular review is sufficient and cancer will not occur.
