MicroRNA molecules were discovered only relatively recently in humans, but have been shown to play a pivotal role in how a cell responds to injury or stress, such as radiation therapy.

Choosing ongoing monitoring instead of immediate curative treatment (surgery or radiotherapy) leads to a better overall quality of life for men with low-risk prostate cancer.
