This course in Cancer Biology introduces students to the complex and multifaceted nature of cancer, a disease affecting one in two individuals during their lifetime. While the alarming prevalence of cancer is counterbalanced by the fact that many cancer deaths are preventable, the course emphasizes the importance of understanding both the genetic and epigenetic factors that contribute to tumorigenesis. Students will delve into the molecular and cellular mechanisms underlying cancer development, as well as the significant role of lifestyle choices in prevention. By integrating basic biological principles with clinical contexts, the course aims to provide a holistic view of cancer, fostering a deeper understanding of its impact on both individual lives and society.
