Earliest Cancer: Despite Paleo Diet

Researchers recently discovered the earliest evidence of cancer in a human fossil. Scientists uncovered a foot bone with evidence of osteosarcoma—an aggressive form of bone cancer—dated approximately 1.7 million years ago.  While the exact species is unknown, it has been determined that the fossil is from a human ancestor.

Today, osteosarcoma is more common in younger people. Scientists are unable to determine if the fossilized bone tumor is from an adult or a child.

Many experts assume that cancer is a group of diseases caused by modern lifestyles and/or changes to the environment. This discovery shows that cancer actually originated millions of years ago—before the modernization of society and before unhealthy behaviors that are so common today.
