MA+Cancer+Article

1. The article begins by mentioning two important people with cancer. Who is Elizabeth Edwards? Who is Tony Snow? (Include their politcal party, job, and current health status-this article was written in April-your answer should have more than what you can find in the article? 2.What is a metastatic cancer cell? 3. Why does the author call cancer cells barbarians and cannibals? 4. What do we know about the events that transform a normal cell to a cancer cell? 5. Why is harder to study metastatic cancer cells? 6. How many cells do primary tumors shed each day (in a rodent)? Yet how many metastatic tumors do these rodents have? 7. Describe two ways metastatic cells can travel through the body avoiding detection from our immune system. 8. Where is the first site (oasis for the cancer cell) that metastasis generally occurs? Why? Why is it an oasis? (What is an oasis?) 9.What is a dormant micrometastasis? Why are they relevant to human health? 10.What evidence do we have that metastasis occurs in organs that are similar to the organ of the primary tumor? Give two examples.
 * Elizabeth Edwards is John Edwards wife. They are democrats and she is currently suffering from a tumor in her rib. Her husband was running for president when her condition returned.
 * Tony Snow is republican and worked as Bush's press secretary. He had colon cancer that spread to his liver.
 * A metastatic cancer cell attacks a body part or area in the body and keeps that area from being able to obtain nutrients. It basically feasts on other cells and inhales the life of all the cells around it. When it is finished doing that it travels on somewhere else.
 * Because they basically eat away at other cells.
 * Genetic mutations and unusual chromosomes cause cells to think they are receiving hormones that stimulate growth.
 * Because metastatic cells work through movement and we would have to study them active in the body.
 * 1 million cells but can be counted on fingrs of metastatic tumors.
 * 1) they become very small(bacteria sized)
 * 2) attract many cells that carry them through the body
 * In an open wound, because it is here that the cells begin to feed on hormones.
 * The metastatic cells that are unsuccessful at reproducing, cells that die, or cells that are dormant.
 * Breast tumors; same cells feast on bone because have calcium just like in the breasts
 * malanoma cells spread to the brain because the nerve cells arise the same as cells that cause melanoma.
