The surgery is a minor surgery and will help the
hernia to not get worse. This type of
surgery is common and is not a big deal. However, surgery in general can cause scarring and has the potential to cause other problems.
So, you can leave the hernia. Perhaps it will get worse or perhaps it will stay the same. Hernias in adults rarely close. Or you can get surgery, it is an outpatient surgery and common. But surgery is surgery and can have deletrious side affects.
