DH+cancer+reading+homework


 * 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
 * 3) Wife of John Edwards
 * 4) Democrat
 * 5) Elizabeth Edwards has taken on huge responsibilities with her husband's campaigns, and is considered to be one of his greatest advisors
 * 6) After visiting her doctor, Edwards found out that the new cancer is mostly in her bone. However, it doesn't seem to be as deadly as the first bat of cancer that she battled. She is recieving treatment depending on how fast the cancer grows.
 * 7) Tony Snow
 * 8) Press secretary to President Bush
 * 9) Tony Snow is a republican
 * 10) What is a metastatic cancer cell?
 * 11) A Metastatic cancer cell is a cell that moves to form a new mass. It is most likely the same cancer, just in a different area of the body
 * 12) Why does the author call cancer cells barbarians and cannibals?
 * 13) The author calls cancer cells barbarians and cannibals because they never die, and they destroy anything in their paths.
 * 14) What do we know about the events that transform a normal cell to a cancer cell?
 * 15) We know that in order for a normal cell to transfer into a cancer cell, there must be a mutation in the genetic code
 * 16) Why is harder to study metastatic cancer cells?
 * 17) It is harder to study metastatic cancer cells because they have changed so much since the first time that they showed up. They are also in a new place, so it's harder to figure out where the cancer originated.
 * 18) How many cells do primary tumors shed each day (in a rodent)? Yet how many metastatic tumors do these rodents have?
 * 19) Rodents shed about a billion cells a day, but only a small number (about what you can count on a hand) metastatic
 * 20) Describe two ways metastatic cells can travel through the body avoiding detection from our immune system.
 * 21) many maligant cells re-invent themselves as parasites, and therefore are able to travel unharmed through our body. They also latch on to or attract red blood cells to carry them to different parts of the body. Almost like an entourage, or an excort.
 * 22) Where is the first site (oasis for the cancer cell) that metastasis generally occurs? Why? Why is it an oasis? (What is an oasis?)
 * 23) What is a dormant micrometastasis? Why are they relevant to human health?
 * 24) A dormant micrometasis is a cell that is "hibernating" so to speak. It's not dead, it's just resting.
 * 25) These cells are relevant to human health because they adapt to their surroundings while dormant, and can even change neighboring cells to become a new tumor
 * 26) What evidence do we have that metastasis occurs in organs that are similar to the organ of the primary tumor? Give two examples.
 * 27) We have evidence that metastasis occurs in organs that are similar to the organ of the primary tumor, because most dormant micrometastasis remain where the first tumor was.
 * 1) We have evidence that metastasis occurs in organs that are similar to the organ of the primary tumor, because most dormant micrometastasis remain where the first tumor was.
