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? >> || Unordered List || 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.
 * 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)
 * Elizabeth Edwards is 57 and is the wife of the presidential candidate John Edwards
 * Tony Snow is 51 and is the press secretary to President Bush
 * malignant cellular outposts proliferating far from the neoplastic mass
 * because the colonist cells co-opting all nutrients in their adopted organ and starving their normal neighbors and blocking traffic and clogging conduits.
 * they also tear open surrounding cells and feast on the meat of their fellows
 * a cell divides and gives rise to a primary tumor
 * [[image:http://c2.wikicdn.com/s/rte/images/list.gif width="22" height="23" caption="Unordered List"]] ||
 * because the cells move and ultimately must be studied in vivo and in the wilderness of the body
 * a million cancer cells are seeded
 * the mice carry bulky tumors of a billion cells each
 * reinventing themselves as parasites and pinching off unnecessary hanks of their cytoplasm
 * attracting an entourage of platelets and red blood cells to their surface to escort them through the rapids into safe pools within tissues
 * wound sites
 * because the cancer cells are able to gain their first toehold in virgin terrain and feed on the broth of growth hormones
 * when a patient harbors thousands or millions of the cancer without suffering a fatal relapse of the disease
 * because the cancer will not atain macro dimensions unless they adapt to their surroundings and interact with their neighbors enough to exploit them
 * because cells learn a skill set from their tissue of origin and some lessons are easily applied to one novel setting than another
 * Breast tumors and the brain
