They are not protected from external forces and are subject to gravity. Many women mistakenly believe that breasts cannot anatomically support themselves and that wearing a brassiere will prevent their breasts from sagging later in life. Researchers, bra manufacturers, and health professionals cannot find any evidence to support the idea that wearing a bra for any amount of time slows breast ptosis. Bra manufacturers are careful to claim that bras only affect the shape of breasts while they are being worn.In fact, there is some evidence that bra use reduces the development of Coopers ligaments, connective tissue that supports breast shape. That atrophy from bra wearing may therefore lead to more breast sag in the long run, much as the connective tissue in a limb weakens while its in a cast and must be re-strengthened afterward. Studies have actually documented that, after an initial period of adjustment, women experienced a significant increase in comfort and breast firmness from going without bras. Surgery
Some women with ptosis choose to undergo plastic surgery to make their breasts less ptotic. Plastic surgeons offer several procedures for lifting sagging breasts. Surgery to correct the size, contour, and elevation of sagging breasts is called mastopexy. Women can also choose breast implants, or may undergo both procedures. The breast-lift procedure surgically elevates the parenchymal tissue (breast mass), cuts and re-sizes the skin envelope, and transposes the nipple-areola complex higher upon the breast hemisphere.
Azathioprine (AZA), sold under the brand name Imuran, among others, is an immunosuppressive medication. It is used in rheumatoid arthritis, granulomatosis with polyangiitis, Crohns disease, ulcerative colitis, and systemic lupus erythematosus, and in kidney transplants to prevent rejection. It is listed by the International Agency for Research on Cancer as a group 1 carcinogen (carcinogenic to humans). It is taken by mouth or injected into a vein.Common side effects include bone-marrow suppression and vomiting. Bone-marrow suppression is especially common in people with a genetic deficiency of the enzyme thiopurine S-methyltransferase. Other serious risk factors include an increased risk of certain cancers. Use during pregnancy may result in harm to the baby. Azathioprine is in the purine analogue and antimetabolite family of medications. It works via 6-thioguanine to disrupt the making of RNA and DNA by cells.Azathioprine was first made in 1957. It is on the World Health Organizations List of Essential Medicines. In 2017, it was the 335th-most commonly prescribed medication in the United States, with more than 800,000 prescriptions. Medical uses
Azathioprine is used alone or in combination with other immunosuppressive therapy to prevent rejection following organ transplantation, and to treat an array of autoimmune diseases, including rheumatoid arthritis, pemphigus, systemic lupus erythematosus, Behçets disease, and other forms of vasculitis, autoimmune hepatitis, atopic dermatitis, myasthenia gravis, neuromyelitis optica (Devics disease), restrictive lung disease, and others.
