Breast skin is thinnest in the lateral and superior breast quadrants (1.38 ± 0.24 mm) and thickest in the medial and inferior breast quadrants (1.97 ± 0.26 mm) (26). Skin thickness, however, significantly decreases with increasing age, with skin starting to thin when a woman is aged in her mid-40s (26, 154).
The mean total skin thickness inclusive of the epidermis and the dermis of the right irradiated side was 0.1712 mm (± 0.03392 mm) compared with the left non-irradiated breast which was 0.1845 mm (± 0.04089 mm; p = 0.007).
The glandular tissue is shown in the transverse section as a triangular grey area embedded in fat. The subcutaneous fatty tissue is 2 to 3 cm thick and the retromammary fatty layer is 1 cm thick.
Thickening of the skin and “peau d'orange”, where the skin of the breast appears pitted like the peel of an orange with large pores, may develop in mastitis or in inflammatory breast cancer, a rare form of breast cancer.

Fibrosis is a thickening of the breast tissue that you and your doctor can feel through the skin. It can be somewhat firm, ropy, or rubbery. Fibrosis also can happen by itself without any cysts forming.
Of the six body regions, the thickest epidermis was found in the dorsum of foot (267.4 ± 120.6 μm), while the thinnest in the breast (76.9 ± 26.2 μm).
Breast and connective tissue are denser than fat and this difference shows up on a mammogram (see images below). High breast density means there's more breast and connective tissue compared to fat.
Breast density reflects the amount of fibrous and glandular tissue in a woman's breasts compared with the amount of fatty tissue in the breasts, as seen on a mammogram. The breasts are almost entirely fatty (about 10% of women). A few areas of dense tissue are scattered through the breasts (about 40% of women).
According to a study conducted by the researchers at the University of Vienna, smaller breasts are likely to be more sensitive than their bigger counterparts. They are also more likely to get easily aroused for increased pleasure.
Breast tissue in and of itself can feel somewhat lumpy and sponge-like, so it can be hard to know if what you're feeling is an actual lump or just normal breast tissue. "A breast lump will feel like a distinct mass that's noticeably more solid than the rest of your breast tissue.
Breast pain can be due to many possible causes. Most likely breast pain is from hormonal fluctuations from menstruation, pregnancy, puberty, menopause, and breastfeeding. Breast pain can also be associated with fibrocystic breast disease, but it is a very unusual symptom of breast cancer.
There's a good reason why most people have voted C Cup as the ideal boob size. The C Cup breast size denotes positive factors such as young age, the right estrogen level and high fertility. C Cup essentially signifies the best matrix in terms of mate selection, as perceived by subconscious evolutionary systems.
The skin on your breasts is thin and delicate, and even the slightest amount of unprotected sun exposure can weaken it. Not only is your chest area at risk for sunburns, but overexposure to the sun can cause dark spots and wrinkles to accumulate on the breast skin.
As females get older, their bodies start to produce less of the reproductive hormone estrogen than before. Estrogen stimulates the growth of breast tissue, while low levels of this hormone cause the mammary glands to shrink.
As you reach the age of 40 years and approach perimenopause, hormonal changes will cause changes to your breasts. Besides noting changes in your breasts' size, shape, and elasticity, you might also notice more bumps and lumps. Aging comes with an increased risk of breast cancer.
Breast density changes with age, for example. On average, older women have lower density breast tissue than do younger women. The greatest change in density occurs during the menopause years. Breast density also changes with certain types of hormone therapies, such as hormone treatments for menopause.
Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick). Male skin is characteristically thicker than female skin in all anatomic locations.
The Epidermis. The epidermis is the outermost skin layer. Its thickness depends on where it is on the body. It's thinnest on the eyelids (roughly half a millimeter) and thickest on your palms and soles (1.5 millimeters).
Skin functions and Layers
Skin is the largest organ of the body. It has an area of 2 square metres (22 square feet) in adults, and weighs about 5 kilograms. The thickness of skin varies from 0.5mm thick on the eyelids to 4.0mm thick on the heels of your feet.
The only way to know the status of a lump for sure is through medical tests, such as an ultrasound, a mammogram, or a fine needle aspiration (FNA), in which your doctor uses a tiny needle to extract a bit of the lump for laboratory examination.
With age, a woman's breasts lose fat, tissue, and mammary glands. Many of these changes are due to the decrease in the body's production of estrogen that occurs at menopause. Without estrogen, the gland tissue shrinks, making the breasts smaller and less full.
Many women have breasts that feel lumpy, thick, and tender, especially right before their periods. These symptoms are called fibrocystic breast changes. They may also be called cyclic breast changes, because they come and go with your menstrual cycle. Fibrocystic breast changes are normal and harmless.
