After more than 5 years the group that received anastrozole had significantly better clinical results than the tamoxifen group. The trial suggested that anastrozole is the preferred medical therapy for postmenopausal women with localized breast cancer, which is estrogen receptor (ER) positive. Another study found that the risk of recurrence was reduced by 40%, but was associated with an increased risk of bone fractures.
The excretory system is a system of organs that removes waste products from the body. When cells in the body break down proteins (large molecules that are essential to the structure and functioning of all living cells), they produce wastes such as urea (a chemical compound of carbon, hydrogen, nitrogen, and oxygen).

Without excretion, waste products build up in the body and cause serious health issues. Urea is a mixture of nitrogenous wastes that damage the body if not removed by the excretory system. Blood is important to the excretory system. It carries waste from cells through the bloodstream to the excretory organs for removal from the body. The excretory system consists of many parts and organs that work as a whole.
