Dear Dr. Burdette ... Sorry, but I don't fully understand the implications of what you are saying. Straightforward ... you are saying that you don't think estrogen CAUSES breast cancer, but merely covers it up so that it lies within the breast undetectable (because of the estrogen). Is that right? Are you also saying that estrogen has no actual CAUSATIVE, nor PREVENTATIVE effect ... but acts PURELY to mask? And, does this then imply that estrogen can serve to impede EARLY detection? Can I ask, also ... what does all of this say of a drug like Tamoxifen? In your opinion? Does something like Tamoxifen indeed WARD OFF breast cancer, or is it merely another MASK? Can Tamoxifen, as well, get in the way of earlier detection? Thank you!! Linda. --------------------------- I would like to add something on all of this. I had my mammogram just last week and after it is done, the radiologist goes over it and compares it to last year. Well, he told me just recently one of his patients at 91 was found to have breast cancer and they didnt know what to do with her being she couldnt go through the operation or chem so all they did was put her on tamoxifen and later the results were amazing as the tumor could not even could be found and the doctor told me it was a rather large tumor that showed on her mammogram. I felt hope from all of this as I have been taking tamoxifen for over 2 years now.and I often wondered about the effects of it all. I thought a good time to share this story. Pauline Answer: Pauline - Excellent time to share this story! This is exactly why Tamoxifen is heralded in its use against breast cancer and definitely what we're all hoping for in using it. I know that the success rates for treating post-menopausal (and certainly 91 is post-menopausal!) are excellent. That was very nice to hear - comforting and reassuring, too. Lynne ---------------------- Hey, I don't get this. How come then, that my BC was Estrogen and Progesterone Receptor Positive!!!!!!! If Estrogen didn't feed it - what did. And why put us on Tamoxifen to stop the estrogen that we produce from working in our bodies. This is bloody confusing. Its frustrating, its a bitch. Is the Doctor talking about women who have been on ERT or HRT who have developed BC, or are those of us who were pre-menopausal at diagnosis, put through an earlier and hasty menopaus - for what ?? I wish God will give us the answers. Ann - Answer: Ann - Agree. It does get confusing. But if you go back and re-read it I think you'll see that it clearly has to do with the use of hormone replacement therapy which is in direct opposition to the use of Tamoxifen. I don't really think what he's talking about has much to do with those of us who already had our breast cancer detected and were found to be estrogen positive. Most of us who were estrogen positive were not using HRT and most who use HRT know that they have to be on the look-out for changes in their bodies regardless of what the medical community might be saying about HRT's low incidence of causing breast cancer. (In essence, I think what he's saying is that if you are on HRT, which we're not! - the use of HRT (estrogen) could be masking cancerous growths when you have your mammograms done.) Don't see that it applies to many on this forum. Worthwhile for people on hormone replacement therapy, though. At times like these it's worthwhile to remember that Tamoxifen has a very successful history of inhibiting cancerous growths in any remaining breast tissue. That's where it scores most of its high marks! Lynne
