=~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)
 * Elizabeth Edwards is the wife of presidential candidate John Edwards of the Democratic party. She is an attorney born on July 3, 1949, in Jacksonville, Florida. She has different cancers that have been treated before. These cancers have now mestasized.
 * Tony Snow is President Bush's press secretary (Republican party). He is fifty one years old, and like Elizabeth Edwards formerly had cancer that has resurfaced.
 * What is a metastatic cancer cell?
 * the spread of a disease from one organ or part to another non-adjacent organ or part
 * Why does the author call cancer cells barbarians and cannibals?
 * Because the cancer cells take away all the nutrients in their adopted organs and starve their neighbors of all the nutrients needed for properly bodily function
 * Because the cancer cells take away all the nutrients in their adopted organs and starve their neighbors of all the nutrients needed for properly bodily function
 * What do we know about the events that transform a normal cell to a cancer cell?
 * Scientists are able to make cells think they are being stimulated growth hormones with genetic mutations and chromosomal aberrations. They can determine and transform from how the cells react to this prompt.
 * Why is harder to study metastatic cancer cells?
 * It is harder because you can't analyze single cells when you have metastatic cancer cells because they are cells always on the mood, so scientists have to study the entire body for these
 * How many cells do primary tumors shed each day (in a rodent)? Yet how many metastatic tumors do these rodents have?
 * Primary tumors shed from a million to even a billion daily
 * You can't the number of metastatic tumors rodents have on one hand
 * Describe two ways metastatic cells can travel through the body avoiding detection from our immune system.
 * 1) The cells can sometimes reinvent themselves as parasites
 * 2) Also they can act like "hitchhikers" and attract an entourage of platelets and red blood cells to their surface to take them to "safe pools" within tissues.
 * Where is the first site (oasis for the cancer cell) that metastasis generally occurs? Why? Why is it an oasis? (What is an oasis?)
 * The first site is gernarlly is at a wound site, which is where the cancer cells seep in and begin to feed on the growth of hormones
 * Because the cancer cells like to attack our normal cells to chance them into cancer cells
 * It is an oasis because it is an ideal place for the cancer cells to go
 * What is a dormant micrometastasis? Why are they relevant to human health?
 * Dormant micromestastasis is when malignant cells have settled into a new site of the body and their replication of more cells can either die or become dormant
 * It is relevant because it allows cancer to lay dormant, so someone could have cancer and not know it
 * What evidence do we have that metastasis occurs in organs that are similar to the organ of the primary tumor? Give two examples.
 * Evidence suggests that micrometastases will not attain macro dimensions
 * unless they adapt to their new surroundings and interact with their neighbors enough to exploit them
 * 2 examples
 * 1) Breast tumors
 * 2) Brain tumors
