Cancer progression - The advancement of cancer due to genetic or epigenetic alterations in tumor cells, involving a complex interplay between tumor cells, surrounding non-neoplastic cells, and the extracellular matrix. Oncogenes - Mutated cellular proto-oncogenes that cause hyper-activation of signaling pathways, contributing to cancer progression by changing the tumor microenvironment, angiogenesis, and inflammation. Tumor suppressors - Genes that, when inactivated, eliminate negative reg...

NR 283 Pathophysiology Exam Questions With Answers Latest Updated 2024 (GRADED) Define the following terms: i. neoplasm: A neoplasm or tumor is a cellular growth that is no longer responding to normal body controls. Cells continue to reproduce when there is no need for them. This excessive growth deprives other cells of nutrients. Many neoplasms are unable to function as normal tissue cells because they consist of atypical (abnormal) or immature cells. ii. benign: Benign tumors usually cons...
