972. Causes, Inheritance: Cancer gene types, Vogelstein clip 2
Professor Vogelstein, explains that cancer is in essence a genetic disease. But it's really quite different than all the other genetic diseases that people usually think of when they think about a genetic disease.
974. Causes, Inheritance: Colon cancer, Vogelstein
Professor Vogelstein explains that APC is expressed in all cells, and that we don't know why it only causes cancers when mutated in the colon and in a few other places.

1013. Diagnosis, Targeted therapies: Targeting activators, Sawyer 1
Professor Charles Sawyer explains that CML stands for chronic myeloid leukemia, which is a blood cancer and it is different from many cancers because it starts very slowly and patients when they're first diagnosed don't have many symptoms.
976. Causes, Inheritance: Many steps to cancer, Vogelstein clip 1
Professor Vogelstein explains that colon cancers provide a good example of a type of tumor in which the genetic steps leading from the normal colon epethelial cell to a cancer, are reasonably well known.
977. Causes, Inheritance: Many steps to cancer, Vogelstein clip 2
Professor Vogelstein explains that the only difference between a benign tumor and a malignant tumor is not the size, it's the ability of the malignant tumor to invade, and get through the tissues.
970. Causes, Inheritance: Cancer gene types
This section identifies that a cancer gene alters the normal functioning of a protein, and there are three major categories of cancer genes.
