Biomedical engineering is expanding very rapidly. Biomedicine techniques and concepts date back to ancient Egypt with a wooden toe (The Whitaker Foundation). The field of biomedical engineering is necessary for the aging baby boomer population. Recent advances since 1990 range from cell-based skin substitutes to robotic surgeons. Progress made in recent years has undoubtedly expanded the overall lifespan of the human race; humans can now live longer and more joyful lives. Many of the advances made in recent years involve creating new treatments for diseases. Over 58% of all deaths in the United States in 1994 were due to AIDS, cancer, and types of heart disease (ieeeghn.org). Today this percentage has been drastically reduced thanks to new drugs and improved medical procedures in the medical field provided by biomedical engineers. If it were not for biomedical engineering, new medicine could not be developed. Bioengineering analysis is pointing to a new path towards better drug design and better drug testing. Cancer disease has taken the lives of many patients, but thanks to new drugs and procedures many others are surviving. Significant progress has been made against cancer, allowing people to live longer, fuller lives. From 1990 to 1991, there were more than one million fewer cancer deaths (aacr.org). As of January 1, 2012, there were 13.7 million survivors in the United States. These numbers are achieved by using new techniques to treat cancer, such as immunotherapies to avoid toxins, targeted cancer therapies to target different types of cancer, and weakened cancerous tumors that make them susceptible to drugs. Cancer is still a significant problem and is far from being cured, but step by step biomedical engineers are getting closer and closer. The recent discovery about AIDS represents a great contribution of engineering to the medical field.
