I want a hysterectomy?

I'm only 14 but I don't want to worry about getting any cancers down there and I always worry about having a std down there too even though I have never had . I think it would be best to get one so I wouldn't worry all the time. I don't want kid and if I decide to raise children I will adopt. I have been thinking about this for about a year.should I grr one and how do you think my parents will react to this.how should I tell them
