 * 1) Give two examples.# 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 the wife of john edwards and tony snow was a secretary to george bush and they both had cancer before but then it metastasized Elizabeths went from breast to bone and Tony's went from colon to kidney.But they both turned out ok.
 * 2)  What is a metastatic cancer cell? A metastatic cancer cell is one that spawns from its birth place in the body and grows widely across the region at a fast pace.
 * 3) # Why does the author call cancer cells barbarians and cannibals? because those cells invade all of the other normal cells taking all of their needs as a cell and also they will engulf the other cells and feast on their nutrients.
 * 4) # What do we know about the events that transform a normal cell to a cancer cell? well the there are so many cells in the body that one is bound to mess up and mutate and when this happens it splits without orders which gives rise to the start of the tumor
 * 5) # Why is harder to study metastatic cancer cells? it is harder to study metastatic cells because millions can lay in the body for long periods of time without detection disguised as other cells
 * 6) # How many cells do primary tumors shed each day (in a rodent)? Yet how many metastatic tumors do these rodents have? millions are shed into the rodents and only 5-7 can me found as tumors
 * 7) # Describe two ways metastatic cells can travel through the body avoiding detection from our immune system. they can turn themselves into parasites or they can latch onto red blood cells and hitch a ride down the blood stream
 * 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?) it is usually a wound because they can feast on virgin cells and growth hormones
 * 9) # What is a dormant micrometastasis? Why are they relevant to human health? they are dormant metastatic cells and millions can live in the body without being detected.
 * 10) # What evidence do we have that metastasis occurs in organs that are similar to the organ of the primary tumor? Give two examples. they begin to become accustom to their surroundings. this happens a lot in breast cancer because will cells will become accustom to the calcium in the milk and use that n=knowledge to invade the bone. it also happens in the brain "presumably because neural tissue and the melanocytes that give rise to melanoma both arise from the same class of cells during gestation."
