Anisomastia is a medical condition in which there is a severe asymmetry or unequalness in the size of the breasts, generally related to a difference in volume. [1] In other words, when one of the breasts is much larger than the other. [2] In contrast to anisomastia, a slight asymmetry of the breasts is common. [1] Anisomastia may be corrected by surgical breast augmentation or reduction. [3]

Estriol chemical compound

Estriol (E3), also spelled oestriol, is a steroid, a weak estrogen, and a minor female sex hormone. It is one of three major endogenous estrogens, the others being estradiol and estrone. Levels of estriol in women who are not pregnant are almost undetectable. However, during pregnancy, estriol is synthesized in very high quantities by the placenta and is the most produced estrogen in the body by far, although circulating levels of estriol are similar to those of other estrogens due to a relatively high rate of metabolism and excretion. Relative to estradiol, both estriol and estrone have far weaker activity as estrogens.

Methyltestosterone chemical compound

Methyltestosterone, sold under the brand names Android, Metandren, and Testred among others, is an androgen and anabolic steroid (AAS) medication which is used in the treatment of low testosterone levels in men, delayed puberty in boys, at low doses as a component of menopausal hormone therapy for menopausal symptoms like hot flashes, osteoporosis, and low sexual desire in women, and to treat breast cancer in women. It is taken by mouth or held in the cheek or under the tongue.

Bicalutamide chemical compound

Bicalutamide, sold under the brand name Casodex among others, is an antiandrogen medication that is primarily used to treat prostate cancer. It is typically used together with a gonadotropin-releasing hormone (GnRH) analogue or surgical removal of the testicles to treat advanced prostate cancer. Bicalutamide may also be used to treat excessive hair growth in women, as a component of feminizing hormone therapy for transgender women, to treat early puberty in boys, and to prevent overly long-lasting erections in men. It is taken by mouth.

Raloxifene chemical compound

Raloxifene, sold under the brand name Evista among others, is a medication used to prevent and treat osteoporosis in postmenopausal women and those on glucocorticoids. For osteoporosis it is less preferred than bisphosphonates. It is also used to reduce the risk of breast cancer in those at high risk. It is taken by mouth.

Oxymetholone chemical compound

Oxymetholone, sold under the brand names Anadrol and Anapolon among others, is an androgen and anabolic steroid (AAS) medication which is used primarily in the treatment of anemia. It is also used to treat osteoporosis, HIV/AIDS wasting syndrome, and to promote weight gain and muscle growth in certain situations. It is taken by mouth.

Toremifene chemical compound

Toremifene, sold under the brand name Fareston among others, is a medication which is used in the treatment of advanced breast cancer in postmenopausal women. It is taken by mouth.

Micromastia Abnormally underdeveloped breasts

Micromastia is a medical term describing the postpubertal underdevelopment of a woman's breast tissue. Just as it is impossible to define 'normal' breast size, there is no objective definition of micromastia. Breast development is commonly asymmetric and one or both breasts may be small. This condition may be a congenital defect associated with underlying abnormalities of the pectoral muscle, related to trauma or it may be a more subjective aesthetic description.

Etonogestrel chemical compound

Etonogestrel is a progestin medication which is used as a means of birth control for women. It is available alone as an implant placed under the skin of the upper arm under the brand names Nexplanon and Implanon and in combination with ethinylestradiol, an estrogen, as a vaginal ring under the brand names NuvaRing and Circlet. Etonogestrel is effective as a means of birth control within 8 hours of insertion.

Breast surgery is a form of surgery performed on the breast.


Scintimammography is a type of breast imaging test that is used to detect cancer cells in the breasts of some women who have had abnormal mammograms, or for those who have dense breast tissue, post-operative scar tissue or breast implants.

Afimoxifene chemical compound

Afimoxifene is a selective estrogen receptor modulator (SERM) of the triphenylethylene group and the major active metabolite of tamoxifen. The drug is under development under the tentative brand name TamoGel as a topical gel for the treatment of hyperplasia of the breast. It has completed a phase II clinical trial for cyclical mastalgia, but further studies are required before afimoxifene can be approved for this indication and marketed.

Prurigo gestationis is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.

Automated whole-breast ultrasound (AWBU) is a medical imaging technique used in radiology to obtain volumetric ultrasound data of the entire breast.


Mammoplasia is the normal or spontaneous enlargement of human breasts. Mammoplasia occurs normally during puberty and pregnancy in women, as well as during certain periods of the menstrual cycle. When it occurs in males, it is called gynecomastia and is considered to be pathological. When it occurs in females and is extremely excessive, it is called macromastia and is similarly considered to be pathological. Mammoplasia may be due to breast engorgement, which is temporary enlargement of the breasts caused by the production and storage of breast milk in association with lactation and/or galactorrhea. Mastodynia frequently co-occurs with mammoplasia.

Breast atrophy Shrinkage of the breasts

Breast atrophy is the normal or spontaneous atrophy or shrinkage of the breasts.

Ethamoxytriphetol chemical compound

Ethamoxytriphetol is a synthetic nonsteroidal antiestrogen that was studied clinically in the late 1950s and early 1960s but was never marketed. MER-25 was first reported in 1958, and was the first antiestrogen to be discovered. It has been described as "essentially devoid of estrogenic activity" and as having "very low estrogenic activity in all species tested". However, some estrogenic effects in the uterus have been observed, so it is not a pure antiestrogen but is, instead, technically a selective estrogen receptor modulator (SERM). For all intents and purposes, it is a nearly pure antiestrogen, however.

ICI-164384 chemical compound

ICI-164384, also known as N-n-butyl-N-methyl-11-(3,17β-dihydroxyestra-1,3,5 -trien-7α-yl)undecanamide, is a steroidal antiestrogen and a synthetic derivative of estradiol which is closely related to fulvestrant and was never marketed. It is a silent antagonist of the estrogen receptor (ER) with no intrinsic estrogenic activity and hence is a pure antiestrogen, unlike selective estrogen receptor modulators (SERMs) like tamoxifen. The drug was under development by AstraZeneca for the treatment of breast cancer but was discontinued in favor of fulvestrant, which is very similar to ICI-164384 but is more potent in comparison.

Zindoxifene chemical compound

Zindoxifene is a nonsteroidal selective estrogen receptor modulator (SERM) that was under development in the 1980s and early 1990s for the treatment of breast cancer but was not marketed. It showed estrogenic-like activity in preclinical studies and failed to demonstrate effectiveness as a treatment for breast cancer in clinical trials. Zindoxifene was the lead compound of the distinct 2-phenylindole class of SERMs, and the marketed SERM bazedoxifene was derived from the major active metabolite of zindoxifene, D-15414. Zindoxifene was first described in 1984.

Adipomastia male breast tissue enlargement solely due to excess fatty tissue

Adipomastia, also known colloquially as fatty breasts, is a condition defined as an excess of skin and adipose tissue in the breasts without true breast glandular tissue. It is commonly present in men with obesity, and is particularly apparent in men who have undergone massive weight loss. A related/synonymous term is pseudogynecomastia. The condition is different and should be distinguished from gynecomastia, which involves true glandular breast development in a male. The two conditions can usually be distinguished easily by palpation to check for the presence of glandular tissue. Another difference between the conditions is that breast pain/tenderness does not occur in pseudogynecomastia. Sometimes, gynecomastia and pseudogynecomastia are present together; this is related to the fact that fat tissue expresses aromatase, the enzyme responsible for the synthesis of estrogen, and estrogen is produced to a disproportionate extent in men with excessive amounts of fat, resulting in simultaneous glandular enlargement.

Onapristone chemical compound

Onapristone (INN) is a synthetic and steroidal antiprogestogen with additional antiglucocorticoid activity which was developed by Schering and described in 1984 but was never marketed. It is a silent antagonist of the progesterone receptor (PR), in contrast to the related antiprogestogen mifepristone. Moreover, compared to mifepristone, onapristone has reduced antiglucocorticoid activity, shows little antiandrogenic activity, and has 10- to 30-fold greater potency as an antiprogestogen. The medication was under development for clinical use, for instance in the treatment of breast cancer and as an endometrial contraceptive, but was discontinued during phase III clinical trials in 1995 due to findings that liver function abnormalities developed in a majority patients.
