 * 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) Elizabeth Edwards is the wife of the presidential candidate, John Edwards. She had been treated for cancer but at age 57 it came back. Hers spread from breast cancer to bone cancer.
 * 3) Tony Snow was the press secretary for president bush and was also re diagnosed with cancer that had been treated at age 51. His spread from colon to liver cancer.
 * 4) What is a metastatic cancer cell? Metastatic cancer is one of the worst cancers someone can have. They can start off as simply a tumor but once the cancer from that tumor spreads is when the cancer can become very dangerous. 90 percent of deaths from cancer are from metastases.
 * 5) Why does the author call cancer cells barbarians and cannibals? The are called cannibals because they take all the nutrients our of their normal organ and take their normal neighbors air, leaving them no air, sugar, or salts. They then eventually just rip open other cells around them and eat them.
 * 6) What do we know about the events that transform a normal cell to a cancer cell? Mutations and aberrations are what start cancer cells. It tricks cells into thinking they are being stimulated by growth horomones when really they are not.
 * 7) Why is harder to study metastatic cancer cells? It is harder to study metastatic cells because they are always moving.
 * 8) How many cells do primary tumors shed each day (in a rodent)? Yet how many metastatic tumors do these rodents have? A mouse has about a million cancer cells in the reodents circulation each day, but their number of visible metastases in these animals is 5 or less.
 * 9) Describe two ways metastatic cells can travel through the body avoiding detection from our immune system. They appear to be just parasites. They also may attach blood cells and other things to them to disguise what they really are.
 * 10) Where is the first site (oasis for the cancer cell) that metastasis generally occurs? Why? Why is it an oasis? (What is an oasis?) AN common oases might be a wound site. This is a common first oases because at a wound site there are many growth hormones which the cancer cells can grab on too and feed on.
 * 11) What is a dormant micrometastasis? Why are they relevant to human health? a dormant one is one that is not fatal, or may not have any affect on the person at all. They do not become a harm or a problem until they begin affecting all the cells around them.
 * 12) What evidence do we have that metastasis occurs in organs that are similar to the organ of the primary tumor? Give two examples. Breast tumors to bone tissue. Mslignant melanoma spreads quickly to the brain.
