Document Summary

Females avoid risk factors better than males so lower mortality rate. Lung cancer most incident in males: acts as a parasite, uses recourses, impairs function of other organs and tissue. Normal cells divide only 50 times: telomere counts the number of times cells divide, divide on demand, signals, cells stay alive when beside like cells (liver cells, will die when taken out of the body. Cancer cells: divide continuously, cancer cells can survive forever. Hala cell: cells that come from uterine cancer cells from henrietta lacks, most popular type of biochemical cells. Malignant cells: mobile, can move through the body and grow. Development: requires 20 years, 8 10 mutations in the same cell have to occur. Cure: every tissue can form a cancer and they can be different cancers from other people. Biological signals: communication happens in the body trough cascading chemical reactions, possibility for something to go wrong in the sequence, any errors from the beginning will be magnified.
