Cancer is not a single disease but rather more than 100 types of disease. Yet all cancer begins with a genetic mutation within a body cell and advances when the cell's descendants mutate further. The following step through from NOVA Online shows the progression of a malignant tumor, ending with metastasis, the colonization of tumors throughout the body. It focuses on the most common type of cancer, a carcinoma, which can originate in the skin, breast, prostate, and other organs.

Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
