Hello Thanks for writing to us with your health concern. Your bleeding qualifies by definition as post menopausal bleeding. Any kind of post menopausal bleeding needs evaluation. I think what you mean by cervical area is actually - endometrial thickness. By ultrasound the thickness of the endometrium ( lining of the uterus ) can be measured. If that is measuring 1.1 cm, it is thicker than normal. It carries a definite risk of endometrial hyperplasia, a few types of which are precursors for endometrial cancer. Yes, it is important to have a D and C and obtain a biopsy of the uterine lining. That will tell you what are your odds of having a cancer. I do not think you need to worry , as the chances are very small, less than 4 % in fact. Being overweight, smoking and diabetes will up the risks though. Proceed with the biopsy as advised and do upload the results so that I can guide you accordingly. All the best. Take care.
