CANCER

Definition of Terms: Cancer- a group of diseases in which cells multiply w/o restraint, destroys healthy tissue, & endangers life Neoplasia – new, altered and abnormal development of cells that may be benign or malignant Tumor – mass or swelling in or on the body Anaplasia – means lack of differentiation Biopsy – the removal & examination of tissue from the living body Carcinogenesis – development of cancerous cells from normal ones Carcinoma – any malignant tumor derived from epithelial tissue Chemotherapy – treatment of disease, especially cancer, by means of chemical agents/drugs Dysplasia – means deranged development, disordered maturation Hyperplasia – constitutes an increase in the number of cells in organ or tissue, which may then have increased Proliferation- refers to the process of cell renewal or replacement. In cancer, proliferation process continues w Differentiation- refers to the process by which cells diversify, acquire specific structural and functional charact Carcinogenesis: the origin of cancer

Wound care with soup and water is sufficient for stings. Scratching is avoided because it result in Histamine responses. Ice application is reduced the swelling and also reduced venom absorption. Oral antihistamine and analgesic can be given to decrease the itching and pain. Epinephrine (aqeous ) injected ubcutaneously-in the case of anaphylactic or sever allergic response. To Minimize you chances Of being a Stung;
