1. Breasts are made up of glands.
• Breasts are apocrine glands.
• These glands are called lobules which consist of thin tubes.
• Fats or adipose tissues, connective tissues, lymph nodes, blood vessels make up the whole of breast internal structure and areola and nipple are the external structures.
2. Breasts are equally producing proficient milk regardless of size.
• Some believed that the larger the breast the more milk is produce; this is actually a myth.
• Breasts size varies considerably which is influenced by several factors such as the amount of breast tissue and familial inheritance or genetic tendencies.
• Either size of the breasts has hormones for lactation sometimes called as ‘mothering hormone – prolactin and oxytocin.
• In addition, breast milk production is not seen until delivery of the baby due to high level of estrogen and progesterone which block prolactin receptors in the breast tissue, thus inhibiting milk production.
3. Breasts of younger women are denser.
• This is due to the volume of glandular tissue greater than adipose tissue.
• Less dense breasts are seen on older women due to having more fat tissues.
4. There are no perfectly symmetrical breasts.
• Left breast is slightly larger (about 10 to 20 percent) than the right breast but are considered normal.
• This is related to the heart’s anatomical location which is slightly deviated to the left.
• Having a greater number of blood vessels and protective fat tissue covering the heart makes the left breast a bit larger.
• Other than breast symmetry, unusual and odd changes (i.e. color changes or skin dimpling) may signify something, talking to a doctor is highly recommended for further evaluation.
5. Some breast deformity can be congenital in origin.
• Cases of breast anomalies are commonly seen in female adolescents.
• Breast hypoplasia is associated with chest wall deformities that affect either one or both breasts (unilateral or bilateral).
• It poses a potential psychological impact on the part of the adolescent as it may evoke sense of low self-esteem or social anxiety.
6. Breasts augmentation is the most popular cosmetic surgical procedures availed by women.
• Silicone implants are done to improve looks of women’s breasts.
• This is commonly observed being widely used by women engaged in sex industry in the exploitation of male entertainment.
7. Breasts do have social and sexual functions.
• Breasts shape and size enhances female body image and attractiveness.
• Breasts are erogenous zone on women’s body which when stimulated causes sexual arousal.
8. Breasts of non human primates only enlarged during lactation.
• Non human primates and other mammal species only develop full breast during reproductive stages and lactation.
• When a female primate has weaned, her breast goes back to non lactating state and flattens back.
9. Breast changes in size at different stages of life.
• In the stage of puberty particularly during telarche, estrogen and growth hormones plays a key role in breast development.
• On woman’s childbearing years (i.e. pregnancy), lobuloalveolar maturation is a physiologic change of breasts (becomes enlarged and denser) to prepare for lactation after childbirth.
• When women reach their menopausal stage menstruation ceases causing a significant decline in estrogen production leading to breast shrinkage and sagging because tissues lose its strength and becomes less dense.
• Furthermore, breasts tend to increase in size over the course of each month.
• Hormones fluctuate (estrogen and progesterone) during menstrual cycle causing the breast to retain water. That is why women may experience slight breast swelling and tenderness before menstruation commences.
10. Breasts of men can get enlarged too.
• Male breast is morphologically identical with that of females’.
• Gynecomastia is the term used to describe abnormal enlargement of male breast.
• The excess breast tissue growth in males is due to imbalance of testosterone and estrogen hormone level.
• It is usually harmless but poses disconcertment and embarrassment among men.
