Pcos, AMH and menopause?

Hello Dr.
I am turning 40 this year and have pcos. Can you explain why my AMH is still very high? 12 years ago it was 10 ng/ml, now it’s 6.85. I also used to have 15 follicles on each ovary, now I have between 20-25.
Does this mean I will have late onset menopause? I am particularly concerned about my risk of ovarian and breast cancer as late onset menopause and pcos are both risk factors. I know that oopherectomies are not usually done prophylactically but I’m having major concerns about my cancer risk. My RE also suggests I go a round of ivf but mentioned, not conceiving after fertility treatment is also a risk factor. At this point, I feel like all these risks make it inevitable that I will get ovarian cancer. Please help.
