Smokeless tobacco and, more recently, e-cigarettes have been promoted as a harm reduction strategy for smokers who are "unable or unwilling to quit."
Epigenetic driver of glioblastoma provides new therapeutic target
Cancer's ability to grow unchecked is often attributed to cancer stem cells, a small fraction of cancer cells that have the capacity to grow and multiply indefinitely. How cancer stem cells retain this property while the bulk of a tumor's cells do not remains largely unknown.
