The role of psychosomatic art therapy in reducing anxiety and promoting psychological adjustment in patients with cancer is based on the view that the experience of cancer is the result of a continuous interaction between physical, emotional, cognitive, and social processes, and that the patient's anxiety is not only a mental reaction in many cases, but is accompanied by changes in body perception and psychophysiological responses. Cancer diagnosis, waiting for test results, initiation of treatment, complications of chemotherapy and radiation therapy, pain, fatigue, changes in body appearance, and worry about the future can create a sense of threat and instability and affect a person's capacity to adapt to new conditions. By providing a creative and relatively non-verbal platform, psychosomatic art therapy allows the patient to express and organize their emotions, worries, and physical experiences in the form of images, colors, forms, music, collages, or writing. This process can help transform the ambiguous experience of anxiety into a visible and conversationable experience, thereby providing a better understanding of emotional stimuli and ways to deal with them. From the perspective of emotion regulation, artistic activity can help identify, tolerate, and moderate unpleasant emotions, giving the patient the opportunity to observe and represent their experience rather than reacting immediately to fear and worry. Focusing on creative activity can also shift the patient's attention for a period of time from recurring thoughts about the illness and its possible consequences to a structured and controllable process. This shift in attention may reduce the intensity of rumination and anxiety arousal, although the extent of this effect depends on individual circumstances and the structure of the intervention. At the psychosomatic level, the reduction of psychological stress can be associated with a reduction in some stress-related responses and a greater sense of calmness, but such changes should not be considered as a direct and definitive effect of art therapy on physiological systems. Research evidence in the field of art therapy and cancer has shown that some art interventions can be associated with a reduction in anxiety, psychological distress, and some emotional symptoms and improve some aspects of quality of life, but the findings are not the same in different studies, and differences in the type of cancer, disease stage, treatment method, type of artistic activity, and characteristics of patients can affect the results. Cancer may reduce a person's sense of control because treatment plans, medications, experiments, and medical procedures affect much of daily life. Artistic activity creates an opportunity for the patient to participate again in a process based on choice and decision-making, and to decide on the color, shape, subject, and way of expressing his work. This experience can help rebuild a sense of empowerment and active participation in the process of coping with the disease. Art also allows for the reconstruction of the narrative of the disease; the patient can organize the experience of diagnosis, treatment, physical changes, fears, and hopes into a visual or written narrative, thereby creating a greater sense of coherence in their personal experience. In patients with cancer, body image changes can also be an important source of anxiety, and art interventions can help to recognize the body, express emotions related to changes in appearance, and create a more harmonious relationship with the body. In the course of chemotherapy, art therapy can be used to reduce anxiety before treatment sessions, increase patient engagement, and create a calmer psychological atmosphere, and in the post-treatment period, it can also help rebuild identity and adapt to life after cancer. In advanced disease or palliative care, artistic activity can allow for the expression of fear, grief, worry about the future, and semantic issues, and reduce the patient's psychological stress. Another application of this approach is to strengthen therapeutic communication, as viewing and discussing the artwork can help the therapist better understand the patient's experience and give the patient himself the opportunity to express his or her needs in a different language. In group interventions, shared artistic experience can foster a sense of belonging and social support, and reduce the sense of isolation caused by illness. However, art therapy should not be considered as a substitute for medical treatment or specialized psychological therapies, and the presence of severe anxiety, significant depression, mental crisis, or new physical symptoms requires appropriate professional evaluation. Research limitations in this area include small sample sizes, differences in treatment protocols, lack of a single standard for the number and duration of sessions, and the use of different tools to measure anxiety and adjustment. It is also unclear how much of the observed works are related to the artistic activity itself and to what extent is related to the therapeutic relationship, social support, attention received, and participation in a regular program. The interpretation of artworks should also be done with caution and should not provide a definitive psychological diagnosis based on symbols or colors; the meaning of the work should be extracted from the patient's personal experience as much as possible. In order to improve the scientific credibility of this field, it is recommended to design protocols based on psycho-oncological assessment, the use of appropriate control groups, larger samples, long-term follow-up and simultaneous measurement of anxiety, emotion regulation, quality of life, adjustment, and indicators related to physical experience. Collaboration between the psycho-oncology, psychologist, art therapist, physician, and other members of the treatment team can also provide a safer and more appropriate intervention to the patient's condition. In general, psychosomatic art therapy can help reduce anxiety and strengthen the psychological adjustment of patients with cancer through the expression and regulation of emotion, directing attention, increasing the sense of control, strengthening self-awareness, reconstructing body image, meaning-making, and social support, and its position in comprehensive care becomes more prominent when it is used in conjunction with medical treatment and based on the psychological and physical needs of each patient in a person-centered manner.
