The two samples taken from the patient's tissues and viewed under the microscope, Sample A from Question 5 and Sample B from Question 9, were part of a diagnostic strategy to identify whether the issue was becoming cancerous. One sample was taken from the suspected cancerous tissue while the other sample was taken from the presumed nearby non-cancerous tissue. Based on your understanding, which of the two samples likely came from the suspected cancerous site on the tissue? Provide two well-explained reasons, with specific details, why you believe that sample is cancerous. Your answer should be based on the information you calculated in this activity and from our material described in our lectures and notes. I have uplode sample A for question 5 and that I marked the question and sample A and the other picture is sample B for question 9. All informations are included in my question.
Cancer is a complicated series of diseases characterized by over-proliferation of cells within a tissue. While in some instances the primary tumor is the ultimate cause of death, in many cases the primary tumor metastasizes, or moves, through the lymph system to invade other tissues. The migration of tumor cells requires changes in the adhesion properties of the cell that allow it to move and invade more readily. There are several molecules involved in cell-to-cell connections and cellular architecture: laminins, matrix metalloproteinases, cadherins, and integrins. While mutations in genes that control the cell cycle or recognize DNA damage are the causes of tumor cell formation, tumor cell spread to other tissues may be caused by mutations in the genes the code for these extracellular proteins. The loss of cellular connections, cellular identification and signaling, and tissue structure may lead to the release of expanding tumor cells into the circulatory and lymphatic systems. Once…
