Hello. Welcome to HCM:
At 40 years of age, an endometrial thickness of more than one 1 cms, needs a biopsy
. If you are not menopausal, it can simply be the proliferative phase. If the climacteric phase (preceeding phase to menopause
) has begun, wherein you may have irregular erratic cycles, it will be helpful to have a biopsy as it will rule out any abnormal uterine proliferation. Currently, there are hormonal
medications for treating this. You can discuss with your gynecologist about these.
