DANE DELION BSN 3 MAIN CATEGORIES OF CANCER PAGE 1 OF 22 Interphase - 90% growth, DNA replication, cell func. G0 - resting stage. Cell leaves to carry out function Carcinoma: cancer that begins in the skin or in tissues that line or cover internal organs Sarcoma: begins in bone, cartilage, fat, muscle, blood vessels, or connective/supportive tissues. Leukemia: begins in blood forming tissue, such as bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and myeloma: begins in cells of the immune system, bone marrow CNS cancers: begin in tissues of the brain and spinal cord; ex: nerve cells: neuroblastoma Classification of Cancer According to behavior of tumor • Benign: • tumors that cannot spread by invasion or metastasis; hence they only grow locally • Malignant: • capable of spreading by invasion/metastasis. • Metastases share name of the primary tumor • Spread to vital organs (liver, brain) — life threatening • • • • Healthy cells Large cytoplasm Single nucleus Single nucleolus Fine chromatin • • • • Cancerous cells Small cytoplasm Multiple nuclei Multiple and large nucleoli Coarse chromatin CELL PARTS & CYCLE Nucleus- control center; controls genetic info Mitochondria- powerhouse; converts sugar to energy via cellular respiration. Ribosomes- site of protein synthesis Golgi apparatus- packaging center of cell; packages & secretes proteins Centrioles- organizes microtubules (spindle fibers) for mitosis Chromosomes- condensed DNA and proteins, codes for genetic traits Endoplasmic Reticulum- Transports intracellular materials. Cell cycle G1- growth and prep of chromosomes for replication S phase- DNA replication occurs G2- prepare for mitosis M phase- mitosis occurs 10% • Prophase: chromosomes condensing; nucleus present • Metaphase- chromosomes line up in middle of cell; nucleus dissembled • Anaphase- chromosomes move away to opposite sides via spindles • Telophase - new nuclei forms on both sides to form new cells. • Cytokinesis- splits cells into 2. Cell cycle quality control: • Checkpoints in G1 & G2 • Apoptosis: self destruction of cell • Mitosis checkpoints: detect failure of spindle fibers & arrest cell in metaphase. • Gene mutations = checkpoint failure = cancer CANCER Gene mutations: 1. Tumor suppressor gene mutations: Cancer cells avoid apoptosis and keep growing and dividing, resulting in a tumor. This is a recessive mutation so both alleles in the gene need to be mutated to cause the cancer. “brakes of a car” 2. Proto-oncogene mutations: dominant genes, only one allele needs to be stated to cause cancer.— proto-onco gene mutates into an oncogene, a cell will keep diving even when there are no messages to divide. “gas of a car” Abnormal cell growth —> Tumor/neoplasm formation —> apoptosis fails —> Invasion & Metastasis Invasion: direct migration and penetration by cancer cells into neighboring tissues Metastasis: ability of cancer cells to penetrate into lymphatic and blood vessels, circulate through the DANE DELION BSN 3 bloodstream, and then invade normal tissues elsewhere in the body. Establishment and growth: tumor cells established and grow in secondary site: lymph nodes or in organs from venous circulation Carcinogenesis Stages: 1. Initiation: carcinogens cause mutations in the cellular DNA. • Spontaneous • Carcinogens: chemicals, physical factors, biologic agents 2. Promotion: allow a cell that has undergone initiation to become cancerous. (Doesn’t affect cells that haven’t undergone initiation). Leads to the formation of pre-neoplastic or benign lesion. • Drugs • Sex hormones 3. Spread/Progression: cancer grows into surrounding tissue or organs (stimulate angiogenesis) , nearby or distant.
