 * Colon Cancer
 * Heart disease is 27% of all death...cancer kills 23% of death
 * heart disease have increased dramatically...cancer rates have not....they haven't gotten worse but has not showed great improvement
 * in men and women lung is most common cancer
 * breast cancer is also a big cause for women
 * prostate is next greatest cause for cancer in males
 * men die more than women from cancer
 * 265,000 in women 285,000 in men (deaths)
 * all races have less cancer
 * asians/pacific islander gets least amount of cancer
 * african america have highest cancer rates
 * african american cancer death rates exceed white men
 * myleloma is the greatest difference in white women and african amercan women
 * african america men have most cancer deaths, white women have least amount of cancer deaths
 * <span style="font-family: Verdana,Helvetica,Arial">prostate cancer is the most common in men but is not as deadly as lung cancer
 * <span style="font-family: Verdana,Helvetica,Arial">breast cancer is the most common cancer in women but it is not as deadly as lung cancer
 * <span style="font-family: Verdana,Helvetica,Arial">1 in 8 women will get breast cancer
 * cancer begins one cell becomes damage or altered which makes it break free from controls that keep our cells working right
 * tissue....group of cells specializing in one part of the body(muscle tissue, nervous tissue..etc)
 * organ: made of a combination of tissues
 * cell divides when it receives a chemical signal
 * cancer cells divide even when they don't receive appropriate signals
 * normal cells are told when to stop dividing when it comes in contact with another cell...cancer cells don't have contact inhibition they keep dividing
 * when the cells don't stop dividing they build up and make a tumor
 * the nucleus is the brain of the cell and contains chromosomes( we have 46)
 * genes are made of nucleic acid and dna...how the info is used make different cells different
 * in cancer changes in dna causes cells to perform differently....all cancers result from changes in dna
 * alteriation in gene=mutation
 * changes are caused by things inhaled like smoking/chew tobacco...sometimes just happens can be caused by tanning bed
 * proto onka gene=has information to trigger cell division(the gas pedal down without a foot)
 * tumor surpressors=genes that break the division...stops the cell from behaving abnormally... like the breaks of the car
 * angeogenesis: growing tumor sends out signals that says "feed me"
 * movement of tumor cells to other parts of the body is metastasis
 * a cell that becomes mutated or damaged will try to fix it and if it doesnt they "commit suicide" this is called apoptosis... if you don't kill yourself this is how you get cancer
