PATH 205.3 Lecture Notes - Lecture 9: Connective Tissue, Weight Loss, Histology
Document Summary
Treatment may not be able to take all of the cancerous cells: may have been discovered at a later stage and is harder to cure. We are able to find more cancer they may not necessarily be increasing. Life spans are becoming longer usually cancer is diagnosed in older people. Neoplasm = new growth the word neoplasms and tumor are often used interchangeably. Cancer = a malignant neoplasm neoplasms can be benign or malignant. Oncology = branch of medicine devoted to treating cancer. Objective 2: describe five basic concepts regarding neoplasia: clonality, cancer as a molecular disease and as mini-evolution, cancer as a cause of death, the age dependent incidence of cancer, benign vs. malignant neoplasms. Colonality all neoplasms derive from one cell. Arise from cells capable of cell division. Sites where there are non-dividing cells, neoplasms come from stem cells (e. g. heart & brain) Cancer as a molecular disease and as mini-evolution.
