@sugarbeez Just came across your post and it caught my interest as someone who has been tested for ET after 9 years of elevated platelets. I ended up having a bone marrow biopsy in April 2023, which did not confirm the diagnosis. So I am just being monitored with a CBC every 4 months to watch platelets. However, I started having very mild female problems in November and went to my obgyn expecting her to say I was beginning menopause. While there, they did a transvaginal ultrasound and found a small cyst on left ovary. She followed up 6 weeks later with another TVUS which showed the cyst had grown slightly. At that time she ordered a CA125 and HE4. Both of those were within normal limits (CA125 at 20 and HE4 at 49.4), but she has referred me on to a gynecologic oncologist for follow up. I see him next week. Prayers for you!
