Malignancy refers to the tendency of a tumor to become progressively worse and eventually spread to other parts of the body. This research area focuses on understanding the mechanisms underlying the development and progression of cancer, as well as developing new approaches for the diagnosis and treatment of malignant tumors. Researchers in this area study various aspects of malignancy, such as genetic mutations, tumor microenvironment, immune response, and metastasis. Ultimately, the goal of malignancy research is to improve the outcomes and quality of life for individuals affected by cancer.
