Genetic counseling and genetic testing for mutations in certain genes—e.g., BRCA1 and BRCA2—can help people understand their risk of certain types of cancer that can run in families, and improve outcomes through prevention, early detection, and targeted treatments, a study conducted at Rutgers Cancer Institutes found.
Tumors are able to form without any DNA mutations, according to a recent proof-of-principle study performed in flies. Epigenetic changes alone—even temporary alterations—induced permanent cancer cell fate.
