Tumor growth is a research area within oncology that focuses on understanding the mechanisms underlying the development and progression of tumors in the body. This research seeks to uncover how tumors form, grow, and spread, with the ultimate goal of developing new treatments and therapies to target cancer cells effectively. Researchers in this area may study a variety of factors that contribute to tumor growth, including genetic mutations, immune responses, and the tumor microenvironment. By gaining a deeper understanding of tumor growth, scientists hope to improve cancer diagnosis, prognosis, and treatment options for patients.
