One of the serious disorders of the human body includes cancer. It is the abnormal proliferation of the otherwise normal cells in the body. The disease is curable through modern medications including at the top Nolvadex of ICI pharmaceuticals. Chemically called as Tamoxifen, its use for the treatment of breast cancer and infertility is popular among the physicians.

Principally, the medicine is an estrogen antagonist for the tissues of breast. It binds the ER, estrogen receptors on the breast cells and blocks the DNA synthesis in the cells and thereby prevents further proliferation of the cells. It is not a catabolic drug rather it is a preventive drug causing cytostasis. It freezes the proliferation of the cancerous cells at their Go and G1 stages of mitosis.
