 * Colon Cancer
 * cancer is number 2 for cause of death, kills almost of half of americans (23.1%)
 * heart disease also accounts for half of Americans death
 * mens leading cancer death: lung
 * womens leading cancer death: lung and breast
 * men die more than women from cancer
 * women used to die more, then switched during 1950s
 * women deaths: 265,000; men deaths: 285,000
 * all women in all races have less cancer than men (in US)
 * African men have the most cancer
 * the least amount of cancer: Asian/Pacific islander
 * african american cancer death rates exceed white men
 * myeloma is the greatest difference in white women and african american women
 * overall- white women have less cancer, african american men have the most
 * estimated US cancer cases: prostate is the most for men, breast cancer is the most for women
 * for men: 1 in 6 will get prostate cancer
 * for women 1 in 8 will get breast cancer

Cancer Biology

 * Introduction to cancer bio
 * begins when a cell in an organ or tissue gets damaged and breaks free of normal controls
 * Bodies, Organs, and Cells
 * various tasks like breathing, blood flow, and digestion are performed by organs.
 * stomach
 * heart
 * lungs
 * tissue is a group of cells that work together to a specific job, muscle tissue, nervous tissue, epithelal tissue, connective tissue
 * Cell division
 * a parent cells splits into two daughter cells through mitosis. they do this through signals.
 * cancer cells divide even if they don't have a signal
 * Normal control of Cell division
 * they are told to divide and when to stop dividing
 * a main signal to stop is when a new cell come in contact with another cell (**contact inhibition**- cancer cells don't have that which causes tumors)
 * Tumor Cells
 * cancer cells don't have contact inhibition which leads to tumors.
 * cells pile on top of each other
 * Cellular Organelles: Nucleus
 * the nucleus is the brain of a cell and contains DNA in the form of chromosomes
 * there are 46 chromosomes in each human nucleus
 * Genes I: Chromosome to DNA
 * genes have individual chromosomes to do different job in different organs
 * Gene Mutation
 * alteration in a gene is called a mutation
 * chemicals found in cigarettes can cause mutations
 * radiation from sun or tanning bed
 * sometimes mutation just happens
 * Genes II: Oncogenes
 * proto-oncogene: information to trigger cell division
 * damage to an proto-oncogene is called an oncogene: mutation in a proto-oncogene
 * Angiogensis
 * tumor cells can spend signals so the body will build blood vessels are tumor
 * it can control the body to bring it blood
 * the tumor controls its building
 * Metastasis: Cancer Cell Migration
 * 90% of deaths from cancer are when tumors move around to other parts of body
 * metastasis is when the cancer cells travel from the original part of the body or organ to another part or organ of the body
 * Cell Death via Apoptosis
 * break down of cells and the death of cells
 * if the cell suicide method is broken, cancer cells can reproduction
