Overtreatment in cancer can result in a range of negative outcomes. Physically, patients may endure unnecessary side effects such as fatigue, nausea, and long-term organ damage. Psychologically, the stress and anxiety associated with extended treatment regimes can be overwhelming. Financially, the cost of excessive treatments can be a significant burden on patients and the healthcare system. Moreover, overtreatment can divert resources from patients who need them more urgently.
