  Cancer is a worldwide epidemic. It is the first or second leading cause of death before age 70 in ninety-one countries, as of 2015. According to the International Agency for Research on Cancer, “there will be an estimated 18.1 million new cancer cases and 9.6 million cancer deaths in 2018,” and cancer is expected to be the “leading cause of death in every country of the world in the 21st century” (Bray, et al. 2018).  While overall cancer mortality has declined in the U.S. annually since 2005, progress has been slow in some cases, and mortality is rising in others.  In particular, “death rates rose from 2010 to 2014 by almost 3% per year for liver cancer and by about 2% per year for uterine cancer,” and, “pancreatic cancer death rates continued to increase slightly (by 0.3% per year) in men” (Siegel, et al. 2017). Perhaps not surprisingly, then, cancer is a central topic of biomedical research, drawing millions of federal dollars annually. In 2019, the U.S. National Cancer Institute (NCI) will allocate $5.74 billion in federal dollars, a $79 million increase over 2018 (NCI, 2019—see the Other Internet Resources).  A search for the term “cancer” in PubMed returns over three million hits.
