Few global challenges touch humanity with as much immediacy or ubiquity as cancer. The good news is that the landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. What Science Knows about Cancer reports from the front lines of the war on cancer with a clear and scientifically precise-yet thoroughly accessible-guide to how the disease develops, thrives, and can potentially be conquered. Taught by David Sadava, a laboratory researcher at the City of Hope Medical Center and an award-winning professor of biology at The Claremont Colleges, this highly visual 24-lecture course leaves no stone unturned in explaining the amazing ways cancer works to subvert the body's normal functioning, and how therapies can reverse these insidious processes.
