Patients with aromatase excess syndrome are characterized by increased E2 levels, pre-pubertal gynecomastia, accelerated bone age in childhood candy96.fun and reduced final adult height due to premature epiphyseal fusion. Excessive estrogen secreted from ovarian component may cause gynecomastia by inhibiting intra-testicular cytochrome P450 C17 activity, leading to decreased testosterone production. However, large-cell lung carcinoma, gastric carcinoma, renal cell carcinoma and rarely hepatoma can lead to the ectopic production of hCG, causing gynecomastia.4,11 In pre-adolescent males with hCG-secreting hepatoblastoma, precocious puberty can also occur. In renal transplantation patients, gynecomastia can also be a side effect of medications, such as cyclosporine. Renal failure leads to hormonal abnormalities, in particular decreased T, increased E2 and LH levels and a modest increase in PRL. The adrenal cortex continues to produce estrogen precursors that get aromatized in the extra-glandular tissues, resulting in an estrogen to androgen imbalance.
Subcutaneous mastectomy is required for removal of glandular tissue and redundant skin (visible inframammary skinfolds) and pain relief. Men with findings suspicious for malignancy or gynaecomastia causing persistent pain or embarrassment should be referred to a surgeon. The aromatase inhibitor anastrazole was no better than placebo for reducing breast volume during puberty20 and was less effective than tamoxifen in men treated with bicalutamide.19 Testosterone replacement for hypogonadal men can be beneficial, but longstanding fibrotic gynaecomastia is unlikely to respond.
It is important for individuals taking these medications to be aware of this potential side effect and consult their healthcare provider if they experience any changes in their breast tissue. It refers to the development of glandular breast tissue in men, resulting in an increase in breast size and sometimes tenderness. AES did the literature review, wrote the section on breast cancer, and prepared figures 2 and 3. Gynaecomastia was thought primarily to be due to conversion of previous high dose androgen to oestrogen in adipose tissue. Examination revealed moderate obesity; normal visual fields; 7 cm tender, firm palpable subareolar breast tissue on the left and 4 cm non-tender tissue on the right; and soft 5 ml testes bilaterally. Liposuction is effective if breast enlargement is mostly caused by adipose tissue and the overlying skin is fairly taut.
Although prolactin (PRL) receptors are present in male breast tissue, hyperprolactinemia may lead to gynecomastia through effects on the hypothalamus, causing central hypogonadism.2,10,11 Activation of PRL also leads to decreased androgen and increased estrogen and progesterone receptors in breast cancer cells. E2 levels rise more rapidly than T during early puberty, which leads to an elevated estrogen/androgen ratio.4,7 In most pre-adolescent males, breast enlargement regresses concomitant with pubertal progression and the rise in T levels and so only small numbers of patients have persistent gynecomastia, and the condition usually spontaneously regresses within two years of onset. However, both conditions involve changes in breast tissue, and having gynecomastia does not increase a man’s risk of developing breast cancer. It is the benign enlargement of male or female breast tissue together, which occurs due to hormonal imbalances or other medical conditions. This review covers the causes, evaluation, and treatment of gynaecomastia and the risk factors for and evaluation and treatment of breast cancer in males. Ashkenazi Jews have a higher prevalence of BRCA1 and BRCA2 and an increased risk of male breast cancer than the general population.13 Male carriers of BRCA2 have a cumulative risk for breast cancer of 7% by age 80.
Finally, family history of gynecomastia should be assessed, which may suggest androgen insensitivity syndrome, familial aromatase excess, or Sertoli cell tumors.2,5,11 A healthy male with long-stable gynecomastia and a negative history and physical examination generally does not require further evaluation. Bodybuilders who abuse anabolic steroids to increase muscle mass may also develop gynecomastia. Males with long-standing type 1 diabetes mellitus may develop diabetic mastopathy, presenting with hard diffuse enlargements of one or both breasts. Increased serum cortisol and E2 levels, combined with decreased serum T, have been reported in patients under extreme stress.
If you've had visible breast tissue for over 12 months, pharmaceutical reversal becomes increasingly unlikely. Less readily available but clinically superior for breast tissue reduction in men. You'll feel a firm lump — not fatty tissue, but actual breast tissue.
Table 3 lists differences in the presentation of gynaecomastia and malignancy. Germ cell tumours produce intratesticular human chorionic gonadotrophin, which can cause dysfunction of Leydig cells and reduced testosterone production. Renal failure has many effects on hormone and drug metabolism. The mechanisms are thought to be similar to those governing gynaecomastia during puberty. Cosmetics, creams, and lotions may contain oestrogens or compounds with oestrogen effects. Oestradiol and oestrone can be interconverted in peripheral tissues (fig 1).
A family history of breast cancer increases the risk of breast cancer in males. Men with Klinefelter’s syndrome, who have testicular failure shortly after puberty, have a 58-fold higher risk than normal males for breast cancer, with an absolute risk that approaches 3%.11 Breast cancer has been reported in male to female transsexuals who were castrated and given high dose oestrogen. We searched Medline for English language papers with the key words "gynaecomastia", "gynecomastia", and "male breast cancer"; the Cochrane database for clinical trials; our personal archives of references; and websites with those terms. But if it’s caused by long-term hormonal imbalances or other medical conditions then treatment is needed to reduce or get rid of the breast tissue.
Withdrawing an offending drug or treating an underlying disorder may be sufficient, especially if gynaecomastia is relatively recent. Most primary breast carcinomas in men are ductal, either invasive or non-invasive (ductal carcinoma in situ).16 Papillary histology is more common and lobular histology is rare in men (fig 3). Mammography is about 90% sensitive and 90% specific for malignant compared with benign masses in men.15 Invasive cancers are solid on ultrasonography. Imaging is not necessary if cancer is not suspected. Other important physical findings include adiposity, signs of hyperthyroidism, liver disease, hypogonadism (gynoid body habitus, decreased body hair, small testes consistent with Klinefelter’s syndrome), excessive musculature indicating exogenous androgen administration, or a testicular mass. Gynaecomastia is characterised by proliferation of ductules and loose connective tissue.
The good news is that most cases resolve naturally as hormone levels stabilize. The key difference is that gynecomastia involves firm glandular tissue, whereas chest fat is softer and can usually be reduced through exercise and diet. Moreover, 30-40% of men aged develop gynecomastia due to hormonal changes that occur with aging.
