Prostate and Breast Cancer


breast-1One type of treatment for prostate or breast cancer involves the use of injectable and implantable drugs and devices called Gonadorelin Analogues. These drugs, such as buserelin, leuprorelin and triptorelin, are administered regularly by injection, ranging from every 4 weeks to every 3 months. They work by affecting the hormones which have an effect on the sex hormones, such as testosterone and oestrogens, helping to treat prostate cancer, some types of breast cancer and they can also be used to treat endometriosis and some types of infertility.

Similar injectable and implantable drugs and devices include other forms of gonadorelin analogues such as goserelin or histrelin. These particular drugs are implantable devices rather than injectable drugs, but they work in a similar way, by reducing the release of follicle stimulating hormone and luteinising hormone, which then in turn reduces the release of sex hormones. These implants are injected every 28 days, or in the case of long-acting implants, every 12 weeks, and continually release the drugs into the bloodstream throughout this time.

These injectable and implantable drugs and devices can help to slow down the progression of prostate and breast cancers, as well as treating endometriosis and helping to treat, in combination with other drugs, infertility. They can help prolong life, as well as aiding the creation of new life, and making conditions more bearable.
