Abstract:
Recent advances in the field of genetics have resulted in the ability to perform genetic tests on individuals to estimate their risk of developing certain diseases. This predictive testing can be used to determine the presence or absence of a specific genetic factor for types of breast, ovarian, colorectal, stomach, and ocular cancers. This article will discuss genetic testing for the cancers listed, including issues surrounding positive results; common issues that arise surrounding genetic testing; what to do when given the results; and what are the available preventative measures.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
