In your assigned readings, you learned how cells divide in order to replace damaged and dead cells. Normally, division is regulated resulting in healthy functional tissue. Cancer occurs when normal regulation of cell division is lost and becomes uncontrolled. Uncontrolled division results in massive reproduction of abnormal cells. Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should. Any disruption of the monitoring system can allow other mistakes to be passed on to the daughter cells. Each successive cell division will give rise to daughter cells with even more accumulated damage. Eventually, all checkpoints become nonfunctional, and rapidly reproducing cells crowd out normal cells, resulting in a tumor or leukemia (blood cancer). For this discussion, you will select a specific cancer. What cell type is affected? Describe the defect in cellular reproduction responsible for the cancer. Discuss therapy available for treatment of the disorder. Does the therapy treat the symptoms or the genetic nature of the disease? Explain. Be sure to use in text citation and provide references for your sources. While not required for this discussion, you may use outside resources. Any materials cited in this course should be referenced using the APA style guidelines Purdue University’s Online Writing LAB (OWL) is a free website that provides excellent information and resources for understanding and using the APA format and style. The OWL website can be accessed here: After posting your discussion on the forum, briefly comment in a constructive manner to at least three of your peer's postings. In your comments, you may for instance refer to how your own experience supports/contradicts the opinions developed by your peers. You may also ask for more detailed examples supporting these opinions, if you think they are too general or not rooted enough in personal experience. In particular, make sure that the examples provided are properly referenced and that you are able to access them. Overall, your comments should contribute positively to the conversation by broadening or clarifying it. In your assigned readings, you learned how cells divide to replace damaged and dead cells.
