Summary
It is important to note that the article explores novel ways of cancer diagnostics and screening methods using blood tests for various signs of the condition. The attempts to implement the practice are currently under the evaluative phase, where the researchers need to show FDA that it is accurate, with benefits substantially outweighing the harms and costs (Johnson par. 12). The given local news article is related to the topic of cells, circulatory system animal transport, genetics, and mitosis.
Mitosis: Cell Division
Firstly, I think that using blood tests to analyze the cancer pathology in a patient is an outstanding objective, which could increase the screening rates and allow people to treat cancers at their early stages of development. When it comes to the subject of mitosis, cancerous cells are usually the result of unregulated cellular division, where cells either lose tumor-suppressing genes or acquire oncogenes. It is possible that one could identify various commonalities between the most dangerous cancer types, which manifest themselves in some form of a biological marker in blood tissue. I would comment that the course material provides an insightful overview of how a multitude of bioprocesses can produce responses which can be tracked and observed.
Circulatory System Animal Transport
Secondly, I would comment on the fact that circulatory system animal transport is also essential for many non-cancer illnesses. One of the most prominent causes of death is cardiovascular disease alongside cancer. Considering that current healthcare practices regularly involve blood test measures, screening for cancerous signs can effectively be implemented into bloodwork. In other words, it is likely that even if such a screening approach is not as effective as traditional means, it will be useful due to a sheer level of accessibility and ease of conducting the process.
Genetics and Cancer Analysis
Thirdly, it is important to comment on the topic of genetics in regard to the article. For example, the author writes that the blood-based screening process focuses on checking for specific DNA fragments expressed by tumor cells (Johnson par. 4). In other words, there are certain genetic and metabolic differences between normal cells and tumor variants. Since the latter is involved in a more dynamic and unregulated cellular division process, the genes expressed in these cells will differ from the regular patterns. If the specific gene or DNA fragments are shed by such cells into one’s bloodstream, it will prove both potent and useful to do a blood screening as a part of a regular blood test.
Cells and Their Role in Blood Analysis
Fourthly, the comments should be provided on the topic of cells themselves from the information derived from the local news article. Cells are complex units of all living organisms, which is why understanding the underlying mechanisms of cellular regulation of growth, division, and internal differences between various types of cells are of paramount relevance. I think blood offers a convenient and informative sample of human cells to create a fuller picture of a patient’s overall condition. Blood not only provides data on diabetes, cardiovascular issues, and the presence of toxicants but also can be used for cancer screening. Therefore, I would further comment on the fact that blood analysis should become a staple of evidence-based medicine, which enables a general overview of a person’s health status.
