Breast cancer development in transsexual subjects receiving cross-sex hormone treatment.
"We researched the occurrence of breast cancer among transsexual persons 18-80 years with an exposure to cross-sex hormones between 5 to >30 years. Our study included 2,307 male-to-female (MtF) transsexual persons undergoing androgen deprivation and estrogen administration (52,370 person-years of exposure)"
"Among MtF individuals one case was encountered, as well as a probable but not proven second case."
"The number of people studied and duration of hormone exposure are limited but it would appear that cross-sex hormone administration does not increase the risk of breast cancer development, in either MtF or FtM transsexual individuals. Breast carcinoma incidences in both groups are comparable to male breast cancers. Cross-sex hormone treatment of transsexual subjects does not seem to be associated with an increased risk of malignant breast development."
The TRANSSEXUAL PHENOMENON
Harry Benjamin, M.D. (FROM THE 1960'S)
"In my own clinical material of 152 male transsexuals, 141 of whom were treated with medium to fairly large doses of estrogen, some over several years, no incident of breast or any other cancer was observed. One may argue that these are mostly young men, less apt to develop a malignancy. The experiences of urologists, however, who treated elderly and old men with even much larger doses of estrogen for cancer of the prostate, must then be recalled. With the exception of one disputed case of breast cancer (it may have been a metastasis of the prostatic cancer) reported in the medical literature, no such incident was observed in hundreds if not thousands of cases. In a personal communication from Dr. Elmer Belt, one of the outstanding and most experienced urologists in the country, he said:
In regard to the taking of Stilbestrol as a cause for cancer of the breast, we have placed several hundred
men on this material (I imagine if we were to search our records we would find the number to be in
excess of two thousand) and in all of these cases we have not seen a single occurrence of cancer of the
breast, although the dosages we used were of a very high level."
You can show this to your doctors. They can't tell you ever again that they refuse to increase dose or what not because of the risk of breast cancer. Mammography also seems useless for us. Very encouraging results indeed.
Especially considering the doses and forms of estrogen used in the past vs the safer forms we use today and MUCH lower doses.
