Postmenopausal bleeding worries

In 2014 l had early stage bilateral breast cancer age 49 and l had the surgery/radiotherapy. I was then put on 20mg tamoxifen for 10 years which l completed November 2024.

I had a transvaginal ultrasound November 2024 which showed endometrial lining at 16mm and cervical smear test negative also ovaries normal for a woman of my age. 

There was no bleeding or any other issues apart from a small stable fibroid which has been there since 2009 

27 October 2025 l saw a litte spotting and by 29th a little bit more. I had another transvaginal ultrasound in the emergency department which showed it was still 16mm, so stable for 1 year. My ovaries were the same etc. A biopsy was tried but failed as l found it too painful. 

My CA 125 blood test has been in the normal range for the last 10 years 

I have regular 3 monthly CT scans with contrast for chest and abdomen (l had thymoma B2 diagnosed 2023 and surgery etc was completed) last CT scan was July 2025 and l have one due in November. All scans have been negative so far. 

I was also diagnosed palb2N in 2023

Getting back to my postmenopausal bleeding l would say is light and hardly anything on a  period towel. I do see blood when l wipe but not significant. Pain is very mild in abdomen and my lifestyle and sleeping pattern has not changed because of it. 

I saw my oncologist yesterday and she has wrote a letter to my gynacologist regarding the bleeding, biopsy issue and discussion of possible hysterectomy .

I see my gynacologist on 13th November to discuss the biopsy under sedation and possibly hysterectomy plus ovaries/fallopian tubes removal. (See past cancer history and genetic mutation) and l suffer from extreme anxiety (so peace of mind would be better for me in the long run)

I am very worried l have cancer again 

I hope l am doing everything right and in time as well, just so very worried
