Tamoxifen is one of three drugs in an anti-angiogenetic protocol developed by Dr. Judah Folkman , a researcher at Children's Hospital at Harvard Medical School in Boston. Folkman discovered in the 1970s that angiogenesis – the growth of new blood vessels – plays a significant role in the development of cancer. Since his discovery, an entirely new field of cancer research has developed. Clinical trials on angiogenesis inhibitors have been underway since 1992 using myriad different drugs. The Harvard researchers developed a specific protocol for a golden retriever named Navy who was cancer-free after receiving the prescribed cocktail of celecoxib , doxycycline , and tamoxifen – the treatment subsequently became known as the Navy Protocol.  Furthermore, tamoxifen treatment alone has been shown to have anti-angiogenetic effects in animal models of cancer which appear to be, at least in part, independent of tamoxifen's ER antagonist properties. 
Do not take Generic Tamoxifen (Tamodex by Biochem) if you are allergic to Tamoxifen (the active ingredient), or to any of its inactive ingredients.
To be sure you are not pregnant, you can start taking Generic Tamoxifen (Tamoxifen) while you are having your menstrual period or, you can take a pregnancy test to be sure you are not pregnant before you begin.
Do not take Tamodex to lower the chance of getting breast cancer if:
• you ever had a blood clot that needed medical treatment
• you are taking medicines to thin your blood, like Warfarin® (also called Coumadin®)
• your ability to move around is limited for most of your waking hours
• you do not have a higher than normal chance of getting breast cancer
Have regular gynecology check-ups, breast exams, and mammograms as per your doctor’s instructions. These will check for signs of breast cancer and cancer of the endometrium (lining of the uterus). Because this medicine does not prevent all breast cancers, and you may get other types of cancers, you need these exams to find any cancers as early as possible.
Tell all of the doctors that you see that you are taking Tamodex (Tamoxifen tablets). Tell your doctor right away if you have any new breast lumps.
