Biomedical engineering is developing very rapidly. Biomedicine techniques and concepts date back to ancient Egypt with a wooden big toe (The Whitaker Foundation). The field of biomedical engineering is needed for the aging baby boomer population. Recent advances since 1990 have brought cell-based skin substitutes to robotic surgeons. The advances made in recent years have undoubtedly extended the overall lifespan of the human race; humans can now live longer, more joyful lives. Many of the advances made in recent years have gone into creating new treatments for diseases. More than 58% of all deaths in the United States in 1994 were due to AIDS, cancer, and certain types of heart disease (ieeeghn.org). Today, this percentage has been significantly reduced thanks to new drugs and improved medical procedures provided by biomedical engineers. Without biomedical engineering, no new medicine would see the light of day. Bioengineering analysis opens a new path to better drug design and testing. Cancer has claimed the lives of many patients, but thanks to new drugs and procedures, many more are surviving. Significant progress has been made in the fight against cancer, enabling people to live longer and better lives. There have been more than 1 million fewer cancer deaths since 1990 and 1991 (aacr.org). As of January 1, 2012, there were 13.7 million survivors in the United States. These numbers are achieved through the use of new techniques to cure cancer, such as immunotherapies to avoid toxins, targeted cancer therapies to target different types of cancer, and weakening cancer tumors making them sensitive to drugs. Cancer remains a significant problem and is far from being cured, but little by little, biomedical engineers are getting closer and closer. The recent discovery of AIDS constitutes a great contribution of engineering to the medical field.
