The Questions Surrounding the Breast Cancer Genes

The process of unraveling the mysteries of the human genome creates enormous possibilities in the world of science. Knowing where on our chromosomes a specific gene lies allows scientists to look inside the human body with more intensity than any X-ray could ever achieve. By analyzing the genetic make-up of human beings, scientists can track diseases back to their most fundamental stages. In recent years, scientists have discovered two genes that play a role in the development of various kinds of cancer in both men and women. With the additional ability to test individuals for their possession of deformed copies of these genes, many ethical questions have been raised. Although the majority of objections surrounding these tests seem to stem from economic and policy issues, there still exist social concerns as well. In time, these issues will have to be dealt with, because as has become increasingly the case, scientific developments preceed, rather than follow, serious ethical and legal thought.

In a healthy body, every one of the 30 trillion cells work together to regulate the transfer of information, movement, and countless other processes. One of the most crucial functions of each cell, however, is to regulate the cell growth itself and of neighboring cells. This is accomplished by creating checks on cell growth, such that no cell is to reproduce unless instructed to do so by those cells around it. When placed in a petri dish with food, a single cell will divide until the copies begin to reach the walls and come in contact with one another. At this point, they will exhibit the property of contact inhibition and will stop growing. Cancer cells, however, "violate this scheme...
