Is it permissible to remove a uterine polyp vaginally, which will affect the hymen and require its later reconstruction, knowing that delaying it may lead to the polyp turning into a tumor?

A surgical procedure is performed if it does not result in harm or extreme hardship, because a transvaginal procedure involves exposure of the major 'awrah (intimate parts) and loss of virginity, which could cause social problems. Restoring the hymen requires exposure of the 'awrah, which is not permissible except out of necessity. However, if the surgical intervention would result in harm or extreme hardship, then the other method is used.
