Introduction:
Normal cells have certain characteristics that are important for the proper functioning of tissues, organs, and body systems, but cancer cells have characteristics that differ from normal cells along with their genetic basis. Cancer can be prevented by diet, exercise, and not using products of tobacco. Along with prevention there is treatment. There is no cure for cancer and it is the second leading cause of death in the United States.
Body Paragraph 1: Cancer Cells VS, Normal Cells
Cancer is the outcome from advancement of abnormal properties in cells that allow the cells to get bigger and spread. This can develop from mutations from chemicals, radiation, replication errors, or ultraviolet light. Viruses also have the capability to cause cancer by changing cell genes. Epstein-Barr Virus (EBV) raises a person’s risk of getting cancer and growing lymphomas. Cancer cells lose adhesion molecules that keep them bonded to cells and the ability to communicate through chemical signals. Cancer cells can reproduce uncontrollably. Like stem cells, cancer replicates many times for long periods of time. Cancer cells do not develop into cells of a specific type.
Body Paragraph 2: Preventing Cancer
Cancer can be prevented by maintaining a healthy diet, avoiding tobacco use, being physically active, …show more content…
When cells undergo unrestricted growth tumors arise. Many genes controlling the cell cycle are also tumor suppressors that stimulate proliferation. Tumor viruses cause tumors to inhibit cell cycle inhibitor genes. The probability of the formation of tumor increases when a tumor suppressor gene mutates. Knudson’s Two-Hit Model proposes that it requires two mutations to lose the function of a tumor suppressor. However, haploinsufficiency is an exception. Mutations in DNA repair genes may be direct cause of some cancer types, because they increase mutation rate
