Psychology holds significant potential as a healing art, comparable to physiology. The placebo effect demonstrates the power of the mind in treatment outcomes, particularly in cancer care, where a positive outlook is beneficial. Effective healthcare involves treating the individual rather than just the disease, emphasizing patient involvement in their treatment. This empowerment fosters a sense of agency, which, while it may not directly save lives, can enhance the quality of life for patients, making their experiences more comfortable and enjoyable.
