Bio of cancer and aids 9/11/15: introductions. Cancer is an old idea naturally occurring in hydra: cancer will never go away as long as there is living organisms and duplicating cells. Metastatic (spreads) and benign (not likely to spread) Cancer happens when a cell"s genetic information is changed and it divides out of control. Majority of people diagnosed with lung cancer die; majority of people diagnosed with prostate cancer survive. Lung cancer is the greatest killing cancer in males and females. The greatest risk for getting cancer is age: old people have been on the earth longer, cells have divided, more chances for cells to make mistakes. Getting treatment in the us gives people about a 90% chance of living longer. Near 1 million in us with aids; 40 million world wide: one in about 300 in our nation, in major cities it"s 2% hiv positive same percentage as major african cities.
