Breast Cancer Treatment: Letrozole is approved for the treatment of hormonally responsive (estrogen receptor-positive) breast cancer in postmenopausal women. By lowering estrogen levels, letrozole helps slow or stop the growth of hormone-sensitive tumors and reduce the risk of cancer recurrence. It is often used as adjuvant therapy after surgery or as first-line therapy in advanced breast cancer.
Infertility Treatment: Letrozole is sometimes prescribed off-label for ovulation induction in women with infertility, particularly those with polycystic ovary syndrome (PCOS) who do not ovulate regularly. Letrozole works by inducing ovulation through its ability to temporarily lower estrogen levels, which can stimulate the release of follicle-stimulating hormone (FSH) from the pituitary gland.
Endometriosis: In some cases, letrozole may be used off-label as a treatment for endometriosis, a condition characterized by the growth of endometrial tissue outside the uterus. By reducing estrogen levels, letrozole may help alleviate symptoms associated with endometriosis, such as pelvic pain and menstrual irregularities.
Gynecomastia: Letrozole may be prescribed off-label for the treatment of gynecomastia, a condition characterized by the enlargement of breast tissue in males. By reducing estrogen levels, letrozole can help shrink breast tissue and alleviate symptoms of gynecomastia.
Hormonal Therapy: Letrozole may also be used in combination with other hormonal therapies, such as gonadotropin-releasing hormone (GnRH) agonists or tamoxifen, for the treatment of hormone receptor-positive breast cancer in postmenopausal women. These combination therapies can help further reduce estrogen levels and improve treatment outcomes.
We extend modifiers to include items that changes the parent and child taxa. I.e. for a species, that would be the genus that is belongs to and the strains in the species.
Impact of letrozole,(prescription) on Conditions from US National Library of Medicine
A higher number indicates impact on more bacteria associated with the condition and confidence on the impact.
We have X bacteria high and Y low reported. We find that the modifier reduces some and increases other of these two groups.
We just tally: X|reduces + Y|Increase = Positive X|increases + Y|decrease = Negative.
Benefit Ratio: Numbers above 0 have increasing positive effect.
Numbers below 0 have increasing negative effect.
