Opioids are substances that act on the nervous system in a similar way to opiates such as morphine and codeine. In a medical context the term usually indicates medications that are artificially made rather than extracted from opium.any of the alkaloids and other derivatives of the opium poppy are not opioids or narcotics; the best example is the smooth-muscle relaxant papaverine. Noscapine is a marginal case as it does have CNS effects but not necessarily similar to morphine, and it is probably in a category all its own.
Modified radical mastectomy This type of mastectomy is usually done to treat invasive cancer that has spread to the lymph nodes. During the mastectomy the breast tissue and a strip of skin with the nipple is removed.
A mastectomy is a surgical procedure in which all or a portion of a breast is removed as a part of treatment for breast cancer. In some cases, mastectomy is performed prophylactically (to prevent cancer from occurring) in women with a high risk for developing breast cancer.
