Scientists receive grant to investigate tumor development within a natural environment

Chemical variations, intercellular activity, and other microenvironmental factors impact cell survival. The relationship between cell and environment also applies to the development of cancer, which a team of Virginia Tech scientists is now researching. After receiving a $1.4 million grant from the National Institutes of Health (NIH), researchers across multiple disciplines are launching a study to investigate tumor development within a natural environment.
