After the occurrence of choriocarcinoma, menstruation usually does not occur. Choriocarcinoma is short for choriocarcinoma, which is caused by cancerous transformation of trophoblast cells of the placenta, and often develops when a woman is pregnant, when the concentration of human hair stimulating gonadotropin in the body will be higher, and regular menstruation will not occur. However, as choriocarcinoma continues to progress, it may cause damage to the endometrial tissue and result in irregular bleeding, which may sometimes be mistaken for menstruation. After the onset of choriocarcinoma, there may not be normal menstruation, and at the same time, there may be uncomfortable symptoms such as persistent lower abdominal pain, fatigue, low fever, etc. Once diagnosed, it is best to remove the diseased tissues by surgery in a timely manner, and cooperate with regular radiotherapy and chemotherapy. When choriocarcinoma is detected, it is necessary to seek medical treatment as early as possible. Only with early detection and early treatment can there be a better prognosis.
