Mussels are the most common source of cancer in the world. Most cancers develop from cells that mutate and multiply within the same individual.

Very rare cancers have acquired the ability to spread from one person to another. This is why it is important to prevent the spread of cancer through the use of mussels as a source of food. The risk of cancer spreading through the mussels is greater if they are in contact with each other. The risks of cancer spread through the Mussels are greater if the Mussel population is not protected.
