CANCER.  Cancer is a group of more than 200 diseases characterized by unregulated growth of cells.  This growth of new cells is called a tumor.  Tumors.

Benign v. Malignant Vocabulary Neoplasm – a new and abnormal growth of tissue in some part of the body Benign – refers to a condition, tumor, or growth.

Intro to Cancer

Statistics Second leading cause of death in US as of 2009] Rising relative to heart disease Over 100 different types of cancer

Comparison of 1900 to 2010

Comparison of Cancer Deaths in Males and Females

Definitions for Cancer Cancer-disease characterized by the uncontrolled, abnormal growth of cells Tumor-abnormal mass of tissue resulting from excessive cell division Malignant-cancerous, will invade adjacent tissues and spread Benign-not cancerous but could transform

5 Main Categories of Cancer • Carcinoma - begins in skin or tissues lining or covering internal organs • Sarcoma - begins in connective or supportive tissue

5 Main Categories of Cancer • Leukemia - starts in blood-forming tissue (ex. bone marrow) • Lymphoma and myeloma - begin in the cells of the immune system • Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord
