Went for my yearly well women examine. I had some vaginal dryness and my Gyno doctor gave me Premarin. I am 63 yrs old and had my uterus remove about 15 yrs ago. I'm just now started to use the Premarin cream. I hadn't used anything before. I'm afraid I don't want cancer. Does this HRT cause cancer. I'm not married so it's not like I have sex a lot . Do I really need to take this? I think it helps with my OA. I have only used it for 2 days.
