Hundreds and thousands of biological reactions occur in the human body during a lifetime.
Findings in a recent experiment conducted by scientists from Harvard and MIT, have uncovered the prominence of mutated cells existing in otherwise healthy subjects. However, most mutations have been classified as non-cancerous.
The wide research was conducted through testing tissues from different parts of the body, such as the liver and skin. Focus was placed on cells that are readily exposed to the environment, such as skin cells.
The landmark study may contribute to an improved understanding of cancer development in tissue mutations.
