Teratomas are curable, and most of them can be treated and cured. The vast majority of teratomas are benign, and only a small percentage of teratomas are malignant. Benign teratomas are better differentiated and can be examined to see hair, bone, teeth, sebum, etc. If the growth rate of such teratomas is slow and the size is relatively small, they do not affect the human body and can continue to be observed. If it is larger or has symptoms of pressure on the surrounding tissues, surgery can be done in time. Malignant teratoma with low differentiation needs to be given surgery in time, and appropriate chemotherapy can be given after surgery to kill the residual cancer cells, which can improve the efficacy of surgery and the quality of survival.
