Abstract:
Cancer survival is increasingly prevalent, and the longevity of survivors enable them to provide insights into the experiences of living with cancer. The objective of this article is to consider the roles that health practitioners play that can facilitate or provide hindrances to investigations and cancer treatment following a diagnosis of cancer. From 2020 to 2022, 81 interviews were conducted with Māori and non-Māori throughout Aotearoa New Zealand identified as having survived cancer for a long time, from 4 to 37 years. Three primary roles were identified from the participants' stories: practitioners as gatekeepers, brokers, and boundary enforcers. We suggest that each of these roles is based on different forms of integrity: professional, personal, and scientific. Findings raise concerns about the potential for the healthcare system to foster iniquitous outcomes and to marginalise those who explore alternative understandings of cancer and its treatment. To better support survivorship the healthcare system could be more expansive in its approach, improve its performance in the capacity to detect cancer signals, particularly in patients with a prior history of disease, and take a more tailored approach to cancer survivorship.

Ethical Concerns in Healthcare:
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
