<s>[INST] Hi, I am 56 and am about 3 years post menopausal. I have lost 18lbs in 4 weeks by dieting . I had severe tiredness and breast tenseness for a week and then vaginal bleeding . I had an ultrasound with no problems notes except 0.7cm reading for uteran thickness. I am so worried this is cancer. I am having a biopsy in the doctors office. Do you think this is likely cancer? [/INST] Thanks for your question on Chat Doctor. In my opinion all your changes are due to menopause and related hormonal changes. After menopause estrogen level start decreasing and this causes atrophy of the genitals including vagina, cervix and endometrium. So all become Chat Doctor.  So endometrial thickness is common finding in post menopause. But bleeding in your case is something worrisome.  So wait for the biopsy report is the only thing we can do. I don't think it is cancer. </s>
