hi, I know a girl who is anorexic and has been for about 3 years, she also hasn t gotten her period in 3 years, I have a few questions. question 1, she suspects she has cervical cancer because of not having her period, could anorexia have caused her to get cancer? question2, is she sterile now because she hasn t had her period in so long? question 3, if she isn t sterile how much longer can she go being anorexic before her ovaries shrivel up and die and becomes sterile?
