(Reuters Life!) - Good news for women in their 50s - the health risks related to hormone therapyTreatment that adds, blocks, or removes hormones. For certain conditions (such as diabetes or menopause), hormones are given to adjust low hormone levels. To slow or stop the growth of certain cancers (such as prostate and breast cancer), synthetic hormones or other drugs may be given to block the body’s natural hormones. Sometimes surgery is needed to remove the gland that makes a certain hormone. Also called hormonal therapy, hormone treatment, or endocrine therapy. with estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. , aimed at treating menopause symptoms, might go away after women stop the treatments, according to a study.
Research focusing on more than 7,000 women showed that while both stroke and bloodA tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes. clots increased during treatment with estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. , there was no significant difference in health risks after 10 years between those who took hormones for treatment and those who hadn't, the study -- published in the Journal of the American Medical Association -- said.
"But that doesn't mean continuing to take them for five to 10 years won't have some health risks emerge," said Graham Colditz, at the Washington University School of Medicine, who wrote an editorial published with the study.
The study centered on some of the women who had also participated in the U.S. government-funded Women's Health Initiative, the study that first raised concerns about the safety of hormone therapyTreatment that adds, blocks, or removes hormones. For certain conditions (such as diabetes or menopause), hormones are given to adjust low hormone levels. To slow or stop the growth of certain cancers (such as prostate and breast cancer), synthetic hormones or other drugs may be given to block the body’s natural hormones. Sometimes surgery is needed to remove the gland that makes a certain hormone. Also called hormonal therapy, hormone treatment, or endocrine therapy. .
In 2004, data from the WHI showed that taking estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. by itself increased women's risk of stroke and didn't reduce their risk of coronary heart disease.
The 7,645 women in the study had all undergone hysterectomies before joining the WHI, and were assigned to a group that received estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. pills. They were followed for 10 years -- six of estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. treatment with Premarin, and four years after ending the treatment.
During the treatment, their risk of stroke was 36 percent more likely and bloodA tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes. clots was 47 percent more likely in the estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. group versus a group that took placebos.
But after 10 years, there was no significant difference between the groups in these conditions.
For women in their 50s, estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. treatment even appeared to have some benefits over time, being linking to a 46 percent drop in the risk of a heart attack and a 27 percent drop in the risk of dying after 10 years.
Women in their 70s, though, did not get the same benefits, and for some conditions their risks rose if they took estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. .
"If you're a woman in your 70s, there's very little reason to initiate estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. ," said Andrea LaCroix for the Fred Hutchinson Cancer Research Center in Seattle and the lead author of the study.
The risk of breast cancerCancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare. in this study appeared to be the same between women who took estrogenA type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones. Estrogens can also be made in the laboratory. They may be used as a type of birth control and to treat symptoms of menopause, menstrual disorders, osteoporosis, and other conditions. and those who didn't, though other studies have found a link between breast cancerCancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare. and hormone therapyTreatment that adds, blocks, or removes hormones.
