Tamoxifen – What is it?
Sold under the trade name of Nolvadex, Tamoxifen is an anti-carcinogenic drug that acts against cancer. In simple words, some cancerous cells grow on estrogen. The cancerous cells have estrogen receptors that get attached to estrogen and multiply the growth of cancerous cells. What Tamoxifen does is, with its ability to attach to estrogen without activating it, gets attached to the estrogen and prevents the cancerous cells from binding with the estrogen and multiplying the cancerous cells. It is usually used in treating breast cancer and is known for its effectiveness on cancerous cells that have spread throughout the body. The drug, apart from being prescribed to people suffering from breast cancer, is also prescribed for reducing the chances of developing breast cancer for women who are exposed to a high risk of developing it. For instance, women whose family members have been diagnosed with breast cancer can take this drug to reduce the risk of developing the disease.
The effectiveness of this was put forth by a study that was carried for over 5 years on about 1500 women. The study showed that the intake of Tamoxifen reduced the chances of development of breast cancer in women by about 44 percent. This effective drug for breast cancer is also used to treat ailments relating to others and not to breast cancer.
