Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body. Cancer can start almost anywhere in the human body, which is made up of trillions of cells
Four main groups of malignant growths:
− Carcinomas – cancers of the epithelial tissue
− Sarcomas – cancers of the connective tissues (bone, muscles, cartilage)
− Leukemias – cancers of the blood
− Lymphoma – cancers of the lymphatic system; less common
Research the different groups of malignant cells and present possible lifestyle contributors to the cellular changes.
