Cancer genetics is a branch of genetics that focuses on the study of genes and genetic variations that contribute to the development and progression of cancer. Researchers in this field study how alterations in specific genes can increase the risk of developing certain types of cancer, as well as how these genetic changes can influence how cancer cells grow and spread. By understanding the genetic factors that drive cancer development, researchers can develop targeted therapies that specifically target the underlying genetic mutations in cancer cells. Cancer genetics research also plays a key role in identifying individuals who may be at higher risk for developing cancer due to inherited genetic mutations, allowing for personalized screening and prevention strategies to be implemented. Overall, cancer genetics research aims to improve our understanding of the genetic basis of cancer and ultimately improve diagnostics, treatment, and prevention strategies for this complex and challenging disease.
