Most Cancer Due to Bad Luck

Description and Advantages

Us Scientists have created a statistical model that measures the proportion of cancer incidence, across many tissue types, caused mainly by random mutations that occur when stem cells divide. By their measure, two-thirds of adult cancer incidence are primarily due to "bad luck," when these random mutations occur in genes that drive cancer growth, while the remaining third are due to environmental factors and inherited genes.
