I had a breast cancer diagnosis Jan 2021 at age 52, mastectomy March 2021, EC-T chemo May-Sept 21 with chemical menopause, Herceptin July 21-August 22. I was started on Letrozole Oct 21, changed to Anastrazole in July 22 then Exemestane Sept 22 until now.
April 22 I had a small bleed and a week of cramping off and on. A trans-vaginal ultrasound found a small 1cm intramural fibroid in the uterus fundus but nothing to explain the symptoms, womb lining nice and thin at 1mm.
A year later in April 23 the same thing happened, but it has continued and the cramping is pretty continuous now with spotting. Another t/v u/s showed I now have thickening of the womb lining to 9mm on the fundus only. The fibroid is unchanged.
I'm expecting a date for a hysteroscopy in the next 3 weeks. The lovely MacMillan nurse here told me that that Exemestane can cause thickening of the womb lining, but I don't know if that would be the whole womb lining rather than just a patch. The nurse also said if this is uterine cancer, it would be unrelated to the original breast cancer, but possibly related to the treatment for it.
I suppose where I'm going with this is to ask whether anyone else has had thickening of the womb lining and cramping/spotting while on Exemestane. I'm clutching at straws while I wait for the hysteroscopy and then for the results. It's going to be a looooong month ahead.
Thank you.
