Neoplasia refers to the process of abnormal cell growth that leads to the formation of a neoplasm, or tumor. This growth can be benign (non-cancerous) or malignant (cancerous). Neoplasms arise when cells begin to divide uncontrollably, often due to genetic mutations or environmental factors. The study of neoplasia is important in understanding various types of cancer and their development. Early detection and treatment of neoplasms can significantly improve patient outcomes. Research in this field continues to explore the mechanisms behind abnormal cell growth and potential therapeutic approaches.
