Letrozole as an anti-estrogen is extremely beneficial to breast cancer patients. Many forms of breast cancer actively feed off the estrogen hormone. By inhibiting the production of estrogen, which in turn lowers the amount of circulating estrogen in the body, this has the ability to starve the cancer. For years Nolvadex was the preferred form of treatment for this purpose. Nolvadex actively binds to the estrogen receptor, thereby preventing estrogen from binding. However, it does not inhibit or lower production. Nolvadex is still extremely valuable in breast cancer treatment plans, but many physicians, especially in extreme cases have begun to use AI’s first. Once the cancer is in remission, at this stage a SERM like Nolvadex may replace the AI in an effort to protect against the cancer reappearing.
Undeniably, AI’s like Letrozole are the most effect means at combating estrogenic related side effects. However, they can also have a negative impact on cholesterol. Alone AI’s do not appear to have a strong, negative effect on cholesterol, but when coupled with an aromatizing steroid like testosterone the adverse cholesterol effect is enhanced. For this reason, many will find SERM’s like Tamoxifen Citrate (Nolvadex) should be their first choice in estrogen protection. SERM’s will not negatively affect cholesterol; in fact, SERM’s, while anti-estrogenic, actively act as estrogens in the liver, and in turn, promote healthier cholesterol levels. We’ll look at this in more detail in the side effect section, and while Letrozole can be used without an adverse cholesterol effect, it will take some effort on your part.
Letrozole is used treat early breast cancer in women who have experienced menopause and who have had other treatments, such as radiation or surgery to remove the tumor. It is also used to treat early breast cancer in women who have experienced menopause and who have already been treated with a medication called tamoxifen (Nolvadex) for 5 years.
Letrozole is also used in women who have experienced menopause as a first treatment of breast cancer that has spread within the breast or to other areas of the body or in women whose breast cancer has worsened while they were taking tamoxifen.
