PN3 EXAM 1 – STUDY GUIDE Cellular regulation is the process of cellular responses in order to undergo reproduction, differentiation, and proliferation. There are many factors that can alter cellular growth and function. To understand this concept there are some term you need to be familiar with: • Neoplasm also referred to as a tumor, is an abnormal mass of cells. A neoplasm can be benign or malignant. • Benign not cancerous; does not metastasize. • Malignant invade and destroy nearby tissues and spread via metastasis. • Metastasis spread of malignant tumor to a location distant to the primary neoplasm. Risk Factors Alteration in cellular regulation can lead to the development of cancer. There are risk factors that promote the development of this life-altering disease process. Some of these factors include: • Age • Heredity • Environment o Pollution o Radiation o Work exposure • Lifestyle o Smoking o Diet o Risky sexual behaviors o Drug use Exemplars When alteration in cellular regulation happens, some of the following disease can develop: • Cancer o Leukemia o Breast cancer o Prostate cancer o Lung cancer o Colon cancer o Skin cancer • Anemia o Sickle cell anemia Treatment Treatment for alteration in cellular regulation can include: • Surgery • Radiation • Chemotherapy • Hormone therapy • Stem Cell transplantation • Complementary and Alternative therapy THE PROCESS OF CHANGING A NORMAL CELL INTO A CANCER CELL IS CALLED MALIGNANT TRANSFORMATION THE ORIGINAL TUMOR IS CALLED THE PRIMARY TUMOR AND IS IDENTIFIED BY THE TISSUE FORM WHICH IT ARROSE, SUCH AS IN BREAST CANCER OR LUNG CANCER METASTASIS OCCURS WHEN CANCER CELLS MOVE FROM THE PRIMARY LOCATION BY. BREAKING OFF FORM THE ORIGINAL GROUP AND ESTABLISHING REMOTE COLONIES CALLED METATSTATIC OR SECONDARY TUMORS CANCER CELLS: ANAPLASIA: LOSES ITS SPECIFIC APPEARANCE LARGER THAN NORMAL NUCLEUS POORLY DIFFERENTIATED AND
