The Cancer Genome Atlas (TCGA) is a comprehensive research project that aims to understand the genetic basis of cancer. It collects and analyzes large amounts of genomic data from various types of cancer, helping researchers identify mutations and alterations in DNA that contribute to the disease. By integrating clinical information with genomic data, TCGA provides valuable insights into cancer biology, which can lead to improved diagnosis, treatment, and prevention strategies. The project has significantly advanced our understanding of cancer and continues to be a vital resource for scientists and healthcare professionals worldwide.
