In the care of children with cancer, therapeutic communication is not merely a means of transmitting medical information, but is an essential component in building trust, reducing the sense of threat, strengthening psychological security, and increasing the child's participation in the treatment process. The experience of cancer in childhood is often associated with exposure to unfamiliar environments, aggressive actions, physical limitations, separation from the natural environment of life, parental anxiety, and widespread dependence on adult decisions, and these conditions can reduce the child's sense of control and agency. Qualitative research has shown that children with cancer feel more respected, secure, and controlled when their informational and developmental needs are taken into account and they are able to express their opinions, concerns, and preferences in interaction with members of the treatment team, while a purely parent-centered relationship may increase the child's feelings of helplessness and incontinence. In such a situation, the psycho-oncologist can enter the care process not merely as a fun or marginal activity, but as a communication medium and targeted psychological intervention. An important feature of art in this field is that the child does not necessarily need a high verbal ability, specialized vocabulary, or direct readiness to talk about the disease; painting, color, collage, construction, visual storytelling, and other artistic media can allow the indirect expression of emotion, fear, anger, ambiguity, hope, and communication needs. Qualitative evidence on creative arts in children with cancer has shown that creative expression can provide the ground for communication, facilitate coping, and activate non-verbal communication. Therefore, the psycho-oncologist can use the artwork as a "communicative text", i.e., instead of hastily interpreting the symbols, ask the child about what he has made, the colors he has chosen, the characters in the image, the parts that have been removed or added, and the meaning he or she has given to the work. This approach moves the child from the position of passive recipient of care to an active participant in the conversation, and allows the professional to receive psychological information through the child's lived experience.
In this process, the role of the psycho-oncologist is not just to perform the artistic activity, but to design and direct a communication process appropriate to the child's age, developmental stage, physical condition, treatment conditions, and preferences. For example, in the early stages of diagnosis, activities such as "the picture of the hospital from my eyes," "the things I was afraid of the treatment," or "the things that make me feel safe" can help identify the child's concerns, while during chemotherapy, painting, or construction can become a tool for conversation about the treatment experience, unpleasant symptoms, the need for support, and ways to increase a sense of control. The importance of this approach lies in the fact that art should not be imposed on the child; the child should have as much choice as possible about the type of activity, the media, the colour, the subject, and even the extent of their participation. This principle is consistent with the evidence on children's participation in treatment decisions; studies show that children with cancer tend to receive information tailored to their circumstances, be heard, and have a role in how they receive care and implement certain aspects of treatment, even if major medical decisions are still the responsibility of adults and the treatment team. From this perspective, art therapy can create a kind of "participation commensurate with the child's capacity", a partnership that does not necessarily mean delegating medical decisions, but rather providing an opportunity to choose, express preference, ask questions, express disapproval, express discomfort, and participate in delegateable decisions.
A child who avoids talking directly about cancer may first connect with free painting or art play, while another child may use visual storytelling or imaginary character construction to express the experience of therapy. In this way, the artwork should not be interpreted mechanically and based on predetermined symbols, as the meaning of a color, shape, or image can be different for each child. The main value of the artwork in this approach is to create an opportunity for dialogue and discover its personal meaning by the child himself. The psycho-oncologist can use statements such as, "Would you like to tell me about this part?" , "If this picture could talk, what would it say?" or "Which part of this painting is more similar to your experience in the hospital?" to develop therapeutic communication through empathetic curiosity. Such an approach is in line with the principles of child-centered communication in pediatric oncology, where the literature emphasizes the importance of building a therapeutic relationship, exchanging information, responding to emotions, managing uncertainty, and providing a context for child participation.
One of the important applications of art therapy in this area is to help reduce the communication distance between the child and members of the treatment team. When a child shows a painting or artwork to a psychologist, nurse, or doctor, the professional can use it as a starting point for a conversation that might normally be difficult for the child. For example, the image that the child paints of the therapy room can lead to the exposure of anxious elements of the environment, the experience of pain, the fear of needles, the worry about nausea, or the feeling of loneliness. This information can be used in coordination with the medical team to personalize psychological support and reduce stressors. In fact, the psycho-oncologist acts as a mediator between the child's subjective experience and the professional language of the treatment team, helping the child's psychological needs not to be ignored in the care program. In addition to transmitting information, effective communication in pediatric oncology also helps to build a therapeutic relationship, support adaptation, and facilitate joint decision-making.
Art therapy, on the other hand, can foster a child's sense of agency. Cancer puts parts of a child's life under the control of medical programs, and the condition may trigger feelings of "my body no longer belongs to me" or "others are deciding about me." Providing small but real choices in art therapy sessions, such as choosing a subject, color, instrument, start or end time, and how the work is presented, can recreate the experience of control. These small choices should not be seen as medical decisions, but rather as part of child-centered care that shows the child that their voice matters. Research on children's participation in cancer has also shown that children value choices about how to receive care, express preferences, and have a sense of control. Therefore, art therapy can be a practical platform for practicing agency, self-expression, and participation.
Psychologically, reducing anxiety can also be an indirect pathway to strengthening communication. An anxious child may ask fewer questions, avoid contact with a therapist, or receive information incompletely. The available evidence on art therapy in children and adolescents with cancer has shown promising effects on some psychological outcomes, although the quality and heterogeneity of the studies remain an important limitation for definitive conclusions. A new systematic review and meta-analysis has also examined the effects of art therapy on psychological outcomes in this group and has highlighted its potential capacity. Relative reduction in anxiety can increase a child's capacity to communicate, receive information, and participate in therapeutic activities; however, art therapy should not replace medical treatment, evidence-based psychotherapy, or direct professional communication, but should be used within the framework of comprehensive and coordinated care.
At the family level, the psycho-oncologist can also use art as a bridge between the child, the parent, and the treatment team. Joint parent-child activities, creating a joint image of "things that help me during therapy," or creating a video booklet of the therapy experience can create an opportunity for family dialogue, but parental involvement should not lead to the child taking over or responding on the child's behalf. In the model The child-parent-specialist triad, preserving the child's voice is of fundamental importance, and the new communication literature in pediatric oncology has also emphasized the importance of tripartite and optimal communication throughtherapeutic alliances. In this process, the psycho-oncologist must manage the boundary between parental support and their replacement with the child, and ensure that the artwork and the conversation surrounding it continue to reflect the child's personal experience.
Despite significant potentials, the use of art therapy to strengthen therapeutic communication also faces limitations. Direct evidence that art therapy specifically increases child participation in therapeutic decision-making is still limited, and a significant portion of the available research has focused on anxiety, psychological distress, quality of life, or treatment-related symptoms, rather than directly on communication participation and decision-making. Even in the child-centred communication literature, new reviews have shown that specific intervention studies are still few and heterogeneous. Therefore, it is necessary to measure indicators such as the level of expression of the child's needs, the number and quality of the child's interactions with the treatment team, the sense of control, satisfaction with communication, age-appropriate participation, trust in the treatment team, and adherence to care, along with indicators of anxiety and distress. Also, age, stage of the disease, type of treatment, cognitive status, family culture, and personal preference of the child should be considered in the design of the intervention. Ultimately, the role of the psycho-oncologist in this model is to create a space in which art is transformed from a side activity into a complementary communicative language, a language that can allow the child to express an experience that is sometimes difficult to express directly, in a visual, symbolic, or narrative way, and through which he can be seen, heard, and participated in the therapeutic relationship to the best of his or her capacity. In such a model, the ultimate goal of art therapy is not simply to produce a work of art, but to create a safe, collaborative, and child-centered relationship in which the child feels included in the treatment process, can ask questions, express their preferences, talk about their experience, and have a choice and voice in areas of care that are appropriate for their age and circumstances.
