Essay on "Finding New and Mysterious Cancer-Causing Genes"

Essay 2 pages (695 words) Sources: 1+

[EXCERPT] . . . .

About half of the genetic mutations "are still unexplained," so there is a dearth of pertinent data (Kean, 1459). It should be pointed out that six years ago scientists thought they had found the main source of breast cancer in BRCA1 and BRCA2, but new and expanded panels (which are genetic tests) continue to be discovered, Kean continues on page 1459.

FIVE: Mathematical Analysis: The data that is being presented is not always easy to evaluate because there are numerous companies involved in the research and their panels (genetic tests) are unique from company to company. "The field has not settled on consistent, evidence-based guidelines," hence it is problematic as to decisions about which panels to test (Kean, 1459). Moreover, there are 100 genes that "might or might not" lead to breast cancer, and mathematically separating the "rogue" genes from the "pretenders" will take more time and add to the mystery of why certain gene mutations cause breast cancer (Kean, 1459).

SIX: Evaluation of Evidence: The author (Kean) does present information that a lay person can understand. In particular, Kean points out the ethical issues involved when doctors have to decide whether to tell a woman about "ambiguous mutations" that may or may not lead to cancer. There is a "moral hazard here," said geneticist Matthew Ellis (quoted by Kean) (1459).

Yes the author presents information that can be researched further and yes I believe the conclusions because they are preceded with science-based factual material.

SEVEN: Application: I have friends and relatives that have suffered from breast cancer, and in several instances, the doctors treating these women were not always certain as to which gene mutation had caused the cancer, and could not predict in advance that breast cancer would be manifested, so I relate to this material. The information in the article is in addition to the class discussions but does not disagree with what has been presented in class.
