Cancer Project Topic


Hi Everyone,

My name is Jaclyn.  I’m interested in the following questions:
1) Why do certain mutational events promote cancer phenotypes in some tissues and not others?

2) Why do most cancers metastasize to the lungs when other organs/tissues are sometimes physically closer to the site at which the cancer originated?  Perhaps there is something special or different about the lung tissue that promotes cancer growth.
Question #2 was sparked by a table (see below) I found at cancer.gov.  I was shocked at how cancer appears to easily spread to the lungs.  This question could even work for the liver and bones, as they are common sites for metastasis as well.
