For cancer patients with tumors, there always a risk of the tumor spreading to a different organ, which makes fighting the cancer more difficult and risky. However, this spread of cancer very rarely occurs on skeletal muscles, which make up nearly 50% of body mass. Why don't these metastatic cancer cells move to and grow on these skeletal muscles? Researchers are still unclear. Now, with the help of a recent $1 million grant from the W.M. Keck Foundation, a research team at Fred Hutchinson Cancer Research Center will focus on studying this elusive topic. (Image courtesy of CC BY-SA 3.0 via Wikimedia Commons)
