RIPPLE MARKS • It’s Catching: Leukemia, Third Known Transmissible Cancer, Infects Soft-Shell Clams

Cheryl Lyn Dybas
First Paragraph

It sounds like the plot of a summer horror flick: malignant cells floating in the sea, ferrying infectious cancer everywhere they go. The story is all too true, say scientists who’ve made a discovery they call “beyond surprising.” Outbreaks of leukemia that have devastated populations of soft-shell clams (Mya arenaria) along the east coast of the United States and Canada are the result of cancerous tumor cells making their way from one clam to another. The finding was reported in 2015 in the journal Cell.
