Most people think of cancer as terrible luck because it is hard to know exactly where it comes from. Scientists are trying to solve this.
Scientists say that they can detect patterns in the DNA of cancers. They call them mutational signatures. It is like cancer forensics. Where did this mutation happen? Why?
Scientists analyzed cancer sequences from over 12,000 patients and found 58 mutational sequences. If they can pull this thread and find the cause of these, they could pinpoint things we could avoid such as certain carcinogens, environmental toxins, foods, etc.
