Cancer diagnosis brings a mix of emotional and psychological challenges for patients. Denial is a common response where patients struggle to accept their condition, even though they are aware of it. This mental defense mechanism can lead to delays in treatment, which may worsen their prognosis. Patients in denial may avoid discussing or thinking about cancer, often delaying necessary treatments or seeking multiple opinions. While denial can offer temporary relief by allowing patients time to process the news, prolonged denial can have serious consequences, like missing out on timely treatment.
