He found on the extreme ends that women with a high breast density developed cancer at a rate five times higher than those with almost entirely fatty breast tissue. [3] It has also been suggested by some researchers, such as in Byrne et al. (1995), that breast density is the greatest risk factor to the development of breast cancer.
In humans, adipose tissue is located: beneath the skin (subcutaneous fat), around internal organs (visceral fat), in bone marrow (yellow bone marrow), intermuscular (muscular system), and in the breast (breast tissue). Adipose tissue is found in specific locations, which are referred to as adipose depots. Apart from adipocytes, which comprise ...
From the cosmetological point of view, it is an important aesthetic component of the breast which should be taken into consideration during various kinds of breast surgery. [1] [2] Histologically, the inframammary fold is an intrinsic dermal structure consisting of regular arrays of collagen held in place by a specialized superficial fascia ...
A typical fat cell is 0.1 mm in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
At the front of the chest, the breast tissue can extend from the clavicle (collarbone) to the middle of the sternum (breastbone). At the sides of the chest, the breast tissue can extend into the axilla (armpit), and can reach as far to the back as the latissimus dorsi muscle, extending from the lower back to the humerus bone (the bone of the ...
A recently published study demonstrates that focal fat pads on the front of human torsos are of mammary ridge origin. Eight pairs of fatty mounds were consistently found running along a curved line from the armpits to the groins in nearly all lean women and men, consistent with the location of the embryological mammary ridge line.
Moreover, suppression of PGE 2 in breast tissue is relevant because, via activation of prostaglandin EP receptors, PGE 2 potently induces amphiregulin expression in breast tissue, and activation of the EGFR by amphiregulin increases COX-2 expression in breast tissue, in turn resulting in more PGE 2, and thus, a self-perpetuating, synergistic ...
Retromammary space is a loose areolar tissue that separates the breast from the pectoralis major muscle. [1] The retromammary space is often the site of breast implantation due to its location away from key nerves and structures that support the breast.
