Neoplasms are abnormal growths of tissue that can occur in any part of the body. They result from uncontrolled cell division and can be classified as benign or malignant. Benign neoplasms do not spread to other parts of the body and are usually not life-threatening, while malignant neoplasms, commonly known as cancers, can invade nearby tissues and metastasize to distant organs. The study of neoplasms is an important aspect of oncology, the branch of medicine that focuses on cancer diagnosis and treatment. Early detection and treatment of neoplasms can significantly improve patient outcomes, making awareness and research in this field crucial for public health.
