Document Summary
Not usually enclosed so they spread to other organs (metastasize) Invade surrounding tissues and emit claw-like protrusions that disrupt the chemical process in health cells(like rna and dna) and create mutant cells. Benign: non-cancerous tumour; harmless to health tissue unless they grow to crowd and block normal tissues and organs like the brain. Ordinary cells are enclosed in fibrous shell/capsules that prevent them from spreading. Metastasis: process by which cancer can spread to different areas of the body. Biopsy: microscopic exam of tissue to determine if cancer is present. Values and beliefs (whether or not you seek treatment) In canada cancer incidence is highest in the atlantic canada and quebec. Lung cancer is the leading cause of premature cancer deaths, second highest for new cases. More men than women are diagnosed and die of cancer (52% or men and 48% of women) 1 in 4 canadians will die of cancer.
