Up to one-half of breast cancer patients who are treated with tamoxifen may develop an endometrial lesion within 6-36 months. Therefore, any patient who develops bleeding while taking tamoxifen requires evaluation. Tamoxifen is a non-steroidal "anti-estrogen" that binds to the estrogen receptor and is used primarily for adjuvant therapy in breast cancer. However, it can also act as a pro-estrogen agonist in a low estradiol environment. The agonist properties can affect the endometrium, and does, in a high percentage of patients (50%). Tamoxifen may cause the endometrium to appear thickened, irregular, and cystic. Most patients tend to have a multiplicity of findings. There is no evidence that screening by ultrasonography (e.g., endovaginal ultrasound or transvaginal ultrasound) reduces mortality from endometrial cancer. Most cases of endometrial cancer (85%) are diagnosed at low stage because of symptoms, and survival rates are high. Based on solid evidence, screening asymptomatic women will result in unnecessary additional biopsies because of false-positive test results. Risks associated with false-positive tests include anxiety and complications from biopsies. There is inadequate evidence that screening by endometrial sampling (i.e., biopsy) reduces mortality from endometrial cancer. Most cases of endometrial cancer (85%) are diagnosed at low stage because of symptoms, and survival rates are high. Endometrial cancer is the most common invasive gynecologic cancer in U. women, with an estimated 63,230 new cases expected to occur in 2018 and an estimated 11,350 women expected to die of the disease. Endometrial cancer is primarily a disease of postmenopausal women, with a mean age at diagnosis of 60 years. Age-adjusted endometrial cancer incidence in the United States has declined since 1975, with a transient increase in incidence occurring from 1973 to 1978, which was associated with estrogen therapy, also known as hormone therapy; there was no associated increase in mortality.

I had been off Tamoxifen as it failed and on Arimidex when I had my first episode of bleeding. Tamoxifen has pro-oestrogenic effects on the endometrium and thus is associated with an increased prevalence of endometrial polyps occurs in ~8-36% of. Has anyone had to have their uterus scrapped due to thickening of the lining? this month marks the 2nd year I have been on Tamoxifen. It appears that Tamoxifen is messing with my uterus. She already told me it's an outpatient surgery and I will have a general anesthesia. Hate to think about what the next years have in store for me. I haven't but I did have an ultrasound about 2 months ago to check and I was ok for now. I spoke with my gynecologist today and she is going to schedule for the procedure. I know that you will have someone give you the right answer, but I just wanted to let you know that I am thinking and praying for you. Hi Bella Luna, I had a D&C for a thicken endometrium. I haven't seen my oncologist in several months, but he did say I would continue with Tamoxifen. I read your post and wanted to share that well within 2-3 years of taking Tamoxifen, I started bleeding (after not having a period for a long time). I had been off Tamoxifen as it failed and on Arimidex when I had my first episode of bleeding. I plan to share my latest hiccup with my oncologist when I get more information. Went to the doctor and they went in and looked at the uterine lining which had thickened. I had many, many endometrium biopsy that were all negative. I ended up with Endometrium hyperplasia with polyps. I know there are other women who had this problem and also had this procedure. They did a D&C and found that some of the cells were pre-cancerous (Dysplasia). A D&C was a very easy procedure, I went in (outpatient), they did their thing (went under, scrape uterus), I woke up and left. My mind is tired, a bad ct scan and a visit to the oncologist will do that I guess. In other words, if left alone would have eventually turned into cancer. I'm sure they'll biopsy the lining and hopefully, you'll be fine.

I also have a large fibroid which has not altered during my year of Tamoxifen and does not bother me, just a little backache occasionally. Although I am postmenopausal I was advised to take Tamoxifen and have had no bad side-effects from it, just a few hot flushes in the early days and I can almost forget that I am on medication. Nada Aug 31, 2008 AM Jaydee wrote: Thanks for your reply, louishenry. Has anyone else continued with Tamoxifen after having this diagnosis? I do need one because the tamox made the fibroids grow even bigger than they already were. I again asked the gynaecologist I saw about the effect of Tamoxifen on fibroids and once again he said it can actually reduce the size because of the limiting effect Tamoxifen has on oestrogen - I agree this is contrary to popular opinion but was quite surprised when he said that my large fibroid (have known about it for years) if anything looks slightly smaller!! I do not want to change to Arimidex as we have a family history of heart conditions and I feel it would add to my worries. Anyhow, hope when I have next ultrasound that my endometrium is back to normal. Have now got a letter of referral with a view to a D&C and possible hysterectomy though not immediately as apparently the lining could be reduced at next ultrasound which I have been told to schedule in 4-6 weeks time. Can't believe I am spending a wet Sunday afternoon in the UK on a cancer board but it has been a godsend to me with the various problems that have niggled me and I find it so re-assuring that we can help each other. Any advice would be appreciated - Best wishes, Jaydee Log in to post a reply Aug 31, 2008 AM louishenry wrote: Hi Jaydee.
