Several factors contribute to the occurrence of inappropriate cancer treatment. Misdiagnosis is a primary cause, where the type or stage of cancer is incorrectly identified. Additionally, lack of access to specialized healthcare facilities and experienced oncologists can lead to suboptimal treatment plans. In some cases, financial constraints or insurance limitations may force patients to opt for less suitable treatment options. Furthermore, the rapid advancements in oncology can sometimes result in outdated treatments being used if healthcare providers are not up-to-date with current protocols.
