The experience of advanced cancer is not just a medical condition, but can be a deep and multi-layered experience that affects the psychological, social, and existential foundations of the individual. In the phenomenological approach, the main focus is on how the patient experiences the disease from the perspective of the patient, i.e., how the individual perceives the disease, the body, the time, the future, the relationships, and the meaning of their life during the encounter with cancer. Advanced cancer can disrupt familiar structures of daily life and confront the patient with realities that were less considered before the disease. Physical limitation, pain, fatigue, dependence on others, changing family and social roles, and awareness of the progression of the disease can alter a person's perception of themselves and the future, setting the stage for experiencing meaninglessness, frustration, and existential threat.
Meaninglessness in the patient's lived experience does not necessarily mean a complete loss of value or interest in life, but can manifest as a sense of disconnect between the current life and the previous semantic system. The goals that the person set for themselves before the illness can no longer be achieved, and as a result, they may have doubts about why they should continue on in life. Job, family, and social roles may change, and activities that were once a normal part of life may become difficult due to physical weakness or medical limitations. In such a situation, the patient may feel that the previous life narrative is no longer compatible with his current situation and that he or she needs a new framework to reconstruct the meaning of life.
From a phenomenological perspective, the body also plays a central role in this experience. A patient with advanced cancer may no longer experience their body as before; the body can become a source of pain, limitation, and worry. Physical changes, reduced mobility ability, complications of treatment, and greater dependence on others may affect a person's sense of independence and identity. As a result, the experience of illness not only remains on a physical level, but also changes a person's perception of the "I" and their place in the world. This change in relation to the body can lead to feelings of vulnerability, shame, alienation from oneself, and a decreased sense of control.
Time also takes on a different meaning in the lived experience of advanced cancer. A person may no longer experience the future as a vast, programmable space, but rather as limited, uncertain, and threatening. Long-term plans may give way to focusing on days and moments nearby. Awareness of the possibility that the future will be shorter can increase the value of the present, but at the same time create anxiety and worry about the time remaining. From this perspective, frustration is not only the result of a negative prediction of the future, but can also be the result of an experience in which the connection between the present and the future is broken.
Hopelessness in patients with advanced cancer can manifest in the form of feelings of inability to change circumstances, reduced expectations for the future, and loss of motivation to plan. However, disappointment is not a monotonous experience and may exist alongside moments of hope and connection with life. Some patients may have limited hope for future medical treatment, but still value visiting family, doing a personal activity, or experiencing peace in the present. Therefore, the phenomenological examination of frustration requires paying attention to the nuances of one's experience and avoiding reducing it to a single psychological symptom.
Existential threat is another essential dimension of the advanced cancer experience. Being aware of the seriousness of the disease can raise questions about death, identity, freedom, responsibility, relationships, the meaning of life, and what will be left of the person. Confronting these questions may be anxious for some patients and an opportunity to reconsider life priorities for others. Existential threat becomes more intense when a person feels that their control over their body, future, or life decisions has been reduced. In this situation, maintaining dignity, independence, and the possibility of choice can become especially psychologically important.
Human relationships play a dual role in this experience. On the one hand, the presence of family and significant others can increase a sense of belonging, security, and worth, and reduce the intensity of existential loneliness. On the other hand, intense dependence on others or worry about becoming a "burden" to the family may create feelings of guilt and worthlessness. Some patients may not talk about their fears and concerns to protect their loved ones, and as a result, an important part of their existential experience remains hidden. Therefore, honest and empathetic communication can provide an important context for processing this experience.
In the context of psycho-oncology, a phenomenological understanding of this experience is of great importance, because effective intervention is possible when the specialist is not limited to clinical diagnoses and also understands the meaning that the patient gives to his or her disease. Two patients with the same medical diagnosis may have completely different experiences of meaninglessness, hopelessness, and existential threat. For one person, the main concern may be the loss of independence; for the other, separation from the family or the unfinished goals of life. Therefore, a person-centered assessment and in-depth dialogue with the patient can be an important part of psychological care.
Meaning-based interventions, supportive psychotherapy, acceptance and commitment-based therapy, and existential approaches can be used in response to these dimensions of experience. The goal of such interventions is not necessarily to eliminate existential questions, but rather to help the patient to face them more tolerably and find sources of meaning appropriate to the current situation. Reconstructing goals, strengthening relationships with important people, maintaining a sense of agency, paying attention to personal values, and creating opportunities to express concerns related to death can help reduce feelings of meaninglessness and helplessness.
The phenomenological explanation of the experience of patients with advanced cancer shows that the disease can change a person's relationship with the body, time, future, others, and the meaning of life. Meaninglessness, frustration, and existential threat are not separate and completely independent phenomena, but in many cases are formed in a complex and intertwined experience. Understanding this experience from the patient's own perspective allows for more humane and profound care. In psycho-oncology, paying attention to these layers of existence can help maintain dignity, reduce suffering, strengthen the connection with life, and improve the quality of the patient's experience in the advanced stages of cancer.
