Feel free to live your life to your own opinion.
QuoteIn my home town I know 2 transgender women with breast cancer. Considering the comparatively small number of transgender women that is a high number.
It's not an opinion. It's a statement based on several studies where authors revealed breast cancer incidence to be very low in transsexual women, close to that of men not on HRT. Are men asked to undergo mammograms?
J Sex Med. 2013 Dec;10(12):3129-34."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 incidence rate of breast cancer in our MtF cohort was thereby 4.1 per 100,000 person-years (i.e., two cases divided by the total amount of 49,370 person-years of follow-up). The 95% confidence interval of the incidence ranged from 0.8 to 13.0 per 100,000 patient-years. For comparison, the calculated expected incidence of breast cancer in biologic women would be 170.0 per 100,000 person-years of follow-up.
In our sample, the one or possibly two incident cases of breast cancer in MtF subjects more closely approximate the expected incidence of breast cancer of 1.2 per 100,000 patient-years that would occur in biologic men."
"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."
Breast Cancer Res Treat. 2015 Jan;149(1):191-8."The purpose of the study was to examine the incidence of breast cancer in the largest North American sample of TG patients studied to date to determine their exposure to CSH, incidence of breast cancer, and to compare results with European studies in transsexual populations. We used Veterans Health Administration (VHA) data from 5,135 TG veterans in the United States from 1996 to 2013 to determine the incidence of breast cancer in this population."
"Ten breast cancer cases were confirmed. Seven were in female-to-male patients,
two in male-to-female patients, and one in a natal male with transvestic fetishism."
3 cases out of 3,556 transsexual women as is indicated in the full article. An incidence rate of 0.08%.
Journal of Clinical & Translational Endocrinology 2 (2015) 55-60"There is no increase in cancer prevalence or mortality due to transgender HT."
"While some guidelines for transgender medical care express concerns for elevated cancer risk with certain hormone regimes, current data suggest that the risk of cancer may not rise."
"Although studies are small, overall cancer incidence in transgender men and transgender women to-date has not been found to be different than their respective male and female controls [5]. There are no reports of change in breast cancer specific risk among transgender individuals on estrogen compared to secular trends of male breast cancer incidence. Rates are lower relative to secular trends of female breast cancer rates."
"Additionally, there are ten case reports of breast cancer development among MTF individuals on estrogen since 1968"
Again, I urge you to consider, in addition to the above... do we ask ciswomen exposed to estrogen for 1-35 yrs to undergo mammograms? No. So why the recommendation in transwomen exposed to estrogen for the same amount of years? Makes no sense, in my opinion.
The situation is different, in so many respects, for transwomen.
Mammograms expose the breast to radiation.Quote from: Cindy on March 25, 2016, 04:09:29 PM
All women should also examine themselves for lumps or changes in breast tissue monthly. If you are unsure how to do that ask your family doctor.
I agree. This is a better, less invasive form of monitoring. This alone, in my opinion, should suffice as long as we are explained in detail how to do this or we can have the doctor do this for us on a yearly basis.
