Experts point out that, like hysteromyoma, the recurrence rate of chocolate cyst is very high, even higher. This is mainly because chocolate cyst can cause lateral adhesion between cyst wall and uterine tissue, and it is difficult to completely remove the cyst by surgery, and most of them will cause cyst rupture and recurrence during the removal process. Some women may choose medication, which may inhibit the growth of the cyst, but the cyst fluid of chocolate cyst will not disappear completely because of medication. When the cyst grows to a certain extent, it will rupture itself due to the increase of tension in the cyst. It can develop from one cyst to two or more cysts, or from one cyst to both sides. Therefore, it is very important to choose a reasonable treatment plan as soon as possible.
