Cancer and mental health are closely intertwined, as the diagnosis and treatment of cancer can have significant psychological effects. Many cancer patients experience anxiety, depression, and emotional distress, which can affect their overall well-being and even their treatment outcomes. The stress of dealing with a cancer diagnosis and the side effects of treatments, such as fatigue and physical changes, can contribute to mental health challenges. Research is increasingly focusing on the psychological impact of cancer and how to provide comprehensive care that addresses both the physical and mental aspects of the disease. Supportive care, including counseling, mindfulness techniques, and peer support groups, is essential in helping patients cope with their emotional health, ultimately leading to better outcomes and improved quality of life.
