World Cancer Day: United by Our Uniqueness

Every year on 4 February, World Cancer Day invites us to reflect on one of the greatest challenges of modern public health.

The goal is not only to confront cancer as a disease, but to face it with knowledge, empathy and shared responsibility. Because cancer touches millions of lives in countless ways, yet it does not define who we are. We are more than a diagnosis, more than a number.

World Cancer Day was established in 2000, following the World Summit Against Cancer for the New Millennium in Paris. It is a core element of the Paris Charter Against Cancer — a global commitment to advancing research, prevention, patient care, awareness and international mobilisation. Since then, the day has served as a reminder that addressing cancer requires long-term vision, cooperation and consistency.

This year’s message, “United by Unique”, highlights a fundamental truth: cancer is not only a medical event.

It is a deeply personal experience. Behind every diagnosis lies a unique human story — stories of fear and loss, but also of resilience, care, love and healing. Every story counts.

Cancer Today: Facts and Challenges

Cancer remains one of the most significant public health challenges in Europe and in Greece. Data from international and European organisations underline not only the scale of the disease, but also the persistent inequalities in prevention, early detection and access to care.

In Europe, approximately 2.7 million new cancer diagnoses are recorded each year, with around 1.3 million deaths, while the economic burden exceeds €93 billion annually. In Greece, cancer is the second leading cause of death, affecting thousands of families and carrying profound social and psychological consequences.

Progress, Prevention and Hope

At the same time, scientific progress offers well-founded reasons for optimism.

Prevention and early detection remain decisive factors. Screening programmes, vaccination, healthy lifestyle choices and access to reliable information can significantly reduce the risk of certain cancers and improve treatment outcomes. In this context, knowledge is not merely information — it is power and a fundamental right.

Advances in cancer management are equally important. Personalised medicine, targeted therapies, immunotherapy and improved management of treatment side effects contribute not only to increased survival rates, but also to a better quality of life for people living with and beyond cancer. Information and education are key tools for both prevention and empowerment.

Mental health plays a crucial role as well. Diagnosis and treatment are often accompanied by anxiety, fear, sadness and emotional exhaustion — affecting not only patients, but also their caregivers. Psychosocial support, counselling services and empowerment groups are essential components of holistic cancer care, helping to preserve dignity and quality of life.

Information, research and mental health care are core pillars of modern cancer management. Indicatively, you may explore the following Kapa3 articles:

Empowerment and Action

World Cancer Day is not just a day of awareness. It is a call to action:

to speak openly about prevention and our health,
to support people living with cancer and their caregivers,
to seek reliable information and evidence-based sources,
to advocate for equal access to care and psychological support,
to remember that no one should face cancer alone.

Because our strength lies in solidarity — and in respecting the uniqueness of every individual.

United by our uniqueness.

Depression and Cancer Mortality: A Critical Link Across Major Cancer Types

Depression is a common but often underrecognized condition among cancer patients, affecting up to 20–30% of individuals diagnosed with the disease. Beyond its impact on quality of life, mounting evidence suggests that depression can significantly influence cancer outcomes, including survival. A recent meta-analysis of 65 cohort studies spanning colorectal, breast, lung, prostate, and mixed cancers provides compelling evidence that depression diagnosed after a cancer diagnosis is associated with a substantially increased risk of mortality.

The analysis revealed that patients with depression faced an 83% higher risk of dying from colorectal cancer, a 59% higher risk in lung cancer, a 74% higher risk in prostate cancer, and a 23% higher risk in breast cancer compared to non-depressed patients. Across mixed cancer types, depression increased the risk of cancer mortality by 38%. These findings underscore that the psychological burden of cancer is not merely an emotional challenge but a critical factor affecting survival outcomes.

Mechanisms Linking Depression and Cancer Outcomes

Depression may influence cancer progression through multiple biological and behavioral pathways. Biologically, depression is associated with chronic systemic inflammation, dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, immune suppression, autonomic dysfunction, oxidative stress, and impaired DNA repair. Elevated pro-inflammatory cytokines, including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), can contribute to tumor growth and metastasis. In older patients, depression may exacerbate age-related immune dysfunction, creating an environment more permissive to cancer progression.

Behaviorally, depression affects health-related actions and treatment adherence. Depressed patients are more likely to delay seeking medical care, adhere poorly to chemotherapy, radiotherapy, and hormonal therapies, and engage in unhealthy habits such as smoking, poor nutrition, and physical inactivity. Social isolation and reduced support systems further increase vulnerability, compounding the negative impact on survival.

Clinical Implications and Interventions

The strong association between depression and cancer mortality highlights the urgent need to integrate mental health care into routine oncology practice. Psychological interventions, such as cognitive-behavioral therapy (CBT), supportive-expressive therapy, and mindfulness-based approaches, have shown promise in reducing distress and improving adherence to cancer treatment. Pharmacological management, including selective serotonin reuptake inhibitors (SSRIs), may also support mental health and potentially influence cancer outcomes, though more research is needed to understand their role fully. Early identification and treatment of depressive symptoms should be considered a priority for oncologists, mental health professionals, and healthcare policymakers alike.

Limitations and Future Directions

While this meta-analysis provides robust evidence, several limitations should be noted. The observational nature of the studies prevents establishing causality, and differences in study design, depression assessment methods, and patient populations contribute to heterogeneity. Future research should explore longitudinal and randomized studies to clarify causal pathways and identify the most effective interventions to reduce depression-related mortality. Investigating the interactions between depression, inflammation, and cancer biology may also reveal targets for novel supportive therapies.

Depression is not just a psychological burden for cancer patients—it is a significant predictor of mortality across multiple cancer types. These findings call for systematic depression screening and tailored interventions as integral components of oncology care.

Organizations like Kapa3 play a vital role in supporting the mental health of cancer patients, offering resources and guidance that can improve both quality of life and treatment outcomes. Integrating psychological support into cancer care ensures that mental well-being is recognized as an essential part of the healing process.
In line with this mission, Kapa3 participates in MELODIC, a new European initiative dedicated to supporting the mental health of young adults (18–30 years old) living with or beyond cancer.
