Cervical Cancer? Please read.

The story of what happened to me is too long to get into here. But I have high grade dysplasia. It took 5 years to get from stage 1 to stage 3. The doctor is refusing treatment because of my anxiety disorder. I'm not looking to talk about that part. There's nothing i can do to change it. I've tried.

My question is, if you've had high grade dysplasia, how long did it take to become cancer? Did it not become cancer at all?

Honesty, I'm trying to figure out how long I have to plan my final arrangements because I didnt even expect to be making any before 40.

The doctor said it's not if, it's when it turns into cancer. Idk if he's right since there's no numbers to find. It all just says some do and some don't. But 5 year survival rates of actual cancer are 5 years. Should I be planning out my last 5 years?

Idk what to do and the gynes response (through her receptionist) was "find a new doctor"
