Why don't all moles progress to melanoma?

...lifetime. Scientists know that 30 percent of all melanomas begin in a mole. They know that 90 percent of moles contain cancer-causing mutations. What scientists didn't know is how melanocytes stop these mutations from triggering the development of cancer. Maria S. Soengas, Ph.D., and other scientists in th...

Study of genomic DNA leads to new advances in cancer diagnostics

...e authors also used flow cytometry to characterize melanomas of varying invasiveness. Further study will be required to determine the specificity and sensitivity of these methods before they are used in the clinical setting. Physicians and researchers alike know that how a cancer cell interacts with its micro...
