Tumor suppression is a research area focused on understanding the mechanisms that prevent the formation and growth of tumors in the body. This field aims to identify the genetic and molecular pathways involved in regulating cell growth and division, as well as the immune response to abnormal cell growth. Researchers in this area study tumor suppressor genes, which are genes that encode proteins that help control cell proliferation and prevent cancer development. By understanding how these genes work, scientists hope to develop new treatments and strategies for preventing and treating cancer.
