It is very unusual for someone to make up a lie about cancer. That is someone who has a tendency to get attention by making up stories - especially stories that can be found out. Don't assume that this is a lie because of her behavior. Women as a whole are very resistant to taking proper action. There are a multitude of fears and that is why low reporting and low follow through are most evident in sexually related offenses. Almost all sexual offenses go unreported. In addition to backlash there is also embarrassment or a concern that they brought this on themselves. I do agree that she is capable of incredible lies so you have no choice but to doubt her but try to verify facts as you did with her father. Did she fail those two courses. You may have to accept that she isn't going to do anything about it. Pull back your support if you are questioning whether it happened.
