JBHA 9.4 Cancer Growth Cell division is essential for healthy growth of an organism and complex genetic mechanisms have evolved to switch cell division on and off at the proper time for normal development. Cancer happens when cells divide uncontrollably and produce a growing lump or tumor. Tumors give out chemical signals that prompt the growth of blood vessels to supply them with oxygen and food. Summarize: CT Screening Dr. Claudia Henschke is leading a campaign to promote CT screening for people at high risk of lung cancer that she says can detect tumors at an early stage. 1 2 3 4 5 6 Epigenetic Therapies. The money raised in 2008's Stand Up To Cancer campaign has already been put to work creating a dream team of doctors developing cutting‐edge research in the fight against cancer. Dr. Jon LaPook reports on a revolutionary approach to fighting cancer called "Epigenetic Therapies." 1 2 3 4 5 6 Option‐ Read more: http://www.cbsnews.com/video/watch/?id=6854630n&tag=related;photovideo#ixzz1LRQCdiWp Animation on how mice are used to study changes in DNA that could also occur in humans and eventually lead to cancer. The genetic similarity of mice to humans accounts for mice being a good experimental model to study cancer. Mouse models that mimic human disease play a vital role in understanding the etiology (cause and origin) of cancer. Results of mouse model studies lend evidence toward the next step in biomedical research that leads to early detection of cancer, new cancer drugs, new combinations of treatments, or new methods such as gene therapy. 1 2 3 4 5 Nanotechnology NCI B‐roll describing the NCI Alliance for Nanotechnology.
