-surgery=there is danger that some cancer cells were left behind, and radiation usually follows surgery. -Radiation Therapy=This breaks down the chromosones and cell sysle disruption. This also breaks the cells up, (dividing cells). This has a lot fo side effects like hari loss, diarrhea, dry, red or irritated skin, blistering burns, or weakness. - Chemotherapy=This is a way to catch the cancer cells that have spread throughout the body. This treats the entire body. Kills the DNA.
 * 1.What three types of therapy are presently the standard ways to treat cancer?** There are three types of therapy tht are presently the standard ways to treat cancer and they are


 * 2. Whhat is an active form of immunotherapy? What is a passive form of immunotheraby for cancer?** To use immune cells, genetically engineered to bear the tumor's antigens. When cancer develops, the immune system had failed to dispose of cancer cells, even though they bear antigens that make them different from teh body's normal cells. A vaccine, called Melacine which contains broken melanoma cells from two different sources is under investigation against melanoma. PAssive immunotherapy is also possible. Monoclonal antibodies are antibodies of teh same type because they are produced by the same plasma cell. To kill monoclonal antibodies better, they are linked to radioactive isotopes or chemotherapeutic drugs.


 * 3. What type of p53 therapy is avaibale?** p53 gene seems to trigger cell death only in cancer cells- that is, elevating the p53 level in a normal cell doesn't do any harm, possible because apoptosis requires extensive DNA damage. When adenoviruses infect a cell, they first produce a protein that inactivates p53. The injected adenovirus spreads through the cancer, killing tumor cells as it goes.

4**. What is the rationale for antiangiogenesis therapy?** Drugs that inhabit angiogensis are a propoed therapy under investigation. Antiangiogenic drugs confine and reduce tumors by breaking up the network of new capillaries in the vicinity of a tumor. Antiangiogenic compounds are currently being tested in clinical trials. Angiostatin and endostatin inhibit angiogenesis in laboratory animals and are expected to do the same in humans.
