Psychosocial oncology addresses the emotional and mental health needs of cancer patients and their families. The diagnosis of cancer can be overwhelming, often causing anxiety, depression, and fear. Psychosocial interventions such as counseling, support groups, and cognitive-behavioral therapy help patients and their families cope with the emotional burden of cancer. Studies show that providing emotional support not only improves mental health but can also enhance physical health outcomes, as patients who are mentally resilient may have better responses to treatment. Integrating psychosocial care into oncology practice ensures that the mental and emotional well-being of patients is given as much attention as their physical care, improving overall quality of life.
