How cancer cells spread and squeeze through tiny blood vessels (video)

(American Chemical Society) The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky. But now scientists are gaining new insights into how cancer cells might squeeze through and even divide within narrow blood vessels while traveling in the body. They report their study using microtubular nanomembranes in the journal ACS Nano.
