Document Summary
Tumour: a mass of tissue that serves no physiological purpose; also called a neoplasm. Benign tumour: a mass of tissue that is not cancerous. Malignant tumour: a mass of tissue that is cancerous and capable of spreading. Lymphatic system: a network of vessels that returns proteins, lipids, and other substances from fluid in the tissues to the circulatory system. Biopsy: the removal and examination of a small piece of body tissue; a needle biopsy uses a needle to remove a small sample, but some biopsies require surgery. Metastasis: the spread of cancer cells from one part of the body to another. Staging: a method of classifying the progress or extent of a cancer in a person. Carcinoma: cancer that originates in epithelial tissue (skin, glands, and lining of internal organs). Epithelia: tissue that covers a surface or lines a tube or cavity of the body, enclosing and protecting other parts of the body.
