Comprehensive Analysis: Natural Disasters and Cancer Care
This detailed analysis explores the intersection of natural disasters and cancer care, focusing on the disruptions faced by patients and the strategies to mitigate these effects. It draws on recent research, case studies, and guidelines to provide a thorough understanding for healthcare professionals, patients, and policymakers.
Background and Significance
Natural disasters, including hurricanes, earthquakes, floods, and wildfires, have increased in frequency and intensity, affecting millions globally. In 2021, 432 natural hazard-related disasters impacted 101.8 million people worldwide (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature). With the global cancer burden expected to reach 28.4 million cases by 2040, a 47% increase from 2020, the vulnerability of cancer patients during disasters is a pressing concern (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature). Cancer care requires continuous, high-level interventions, and disruptions can lead to treatment delays, with even short delays (e.g., 2 days) negatively affecting survival for some cancers (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature).
Impact on Cancer Care
Natural disasters disrupt cancer care through multiple pathways, as evidenced by systematic reviews and case studies. A 2018 review by Man et al. found that disasters cause substantial interruptions to oncology services, including damage to infrastructure, communication systems, medicine supply disruptions, and medical record loss (The effect of natural disasters on cancer care: a systematic review). Specific challenges include:
- Access and Continuity: Disasters can render hospitals inaccessible, with case studies like Hurricane Katrina showing decreased cancer-specific survival times, particularly among older adults (Impact of Disasters on Older Adult Cancer Outcomes: A Scoping Review). Hurricane Sandy also delayed chemotherapy, radiotherapy, and surgery for gynecologic cancer patients (Impact of Disasters on Older Adult Cancer Outcomes: A Scoping Review).
- Medication and Treatment: Patients may lose access to cancer medications, leading to health risks if treatments are suddenly stopped. The American Cancer Society highlights that limited access to medicines can cause issues, especially for pain or depression management (Coping with Cancer After a Natural Disaster: Frequently Asked Questions for Cancer Patients and Their Caregivers).
- Infection Risks: Shelters increase infection risks for immunocompromised patients, particularly post-chemotherapy, due to crowded conditions and poor sanitation (Coping with Cancer After a Natural Disaster: Frequently Asked Questions for Cancer Patients and Their Caregivers).
- Psychological and Social Effects: Disasters exacerbate psychological stress, with social isolation contributing to treatment delays (Cancer Patients During and after Natural and Man-Made Disasters: A Systematic Review). A study on seismic activity showed significant barriers to healthcare access, highlighting the psychosocial impact (The effect of natural disasters on cancer care: a systematic review).
An unexpected finding is the long-term vulnerability of older cancer patients to carcinogenic exposures from floods and wildfires, which may contribute to cancer onset or progression, as noted in a review of older adult outcomes (Impact of Disasters on Older Adult Cancer Outcomes: A Scoping Review).
Case Studies and Real-World Examples
Real-world examples illustrate these impacts:
- Hurricane Katrina (2005): A study found that 56% of newly diagnosed cancer patients were over 65, with decreased survival times across all cancers, particularly for older adults, due to disrupted care (Impact of Disasters on Older Adult Cancer Outcomes: A Scoping Review).
- Typhoon Haiyan: A case report described limited interventions for older adult head and neck cancer patients, highlighting triage challenges in disaster settings (Impact of Disasters on Older Adult Cancer Outcomes: A Scoping Review).
- Earthquake in Italy (2009): A home care service faced problems like infrastructure damage and transportation collapse, affecting cancer patient care (Cancer Care After Natural Disaster: Different Countries, Similar Problems).
These cases underscore the need for tailored disaster planning for cancer patients, especially in vulnerable regions like Asia, where 60% of the global population contributes to nearly half of new cancer cases and over half of cancer deaths (Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care).
Strategies for Mitigation and Protection
To reduce disruptions, both patients and healthcare systems can adopt preparedness measures, as outlined in various guidelines and reviews:
Patient and Caregiver Strategies
The American Cancer Society provides practical advice for patients, including:
- Emergency Planning: Discuss plans with providers, make family plans, and know diagnosis details (Coping with Cancer After a Natural Disaster: Frequently Asked Questions for Cancer Patients and Their Caregivers).
- Emergency Kit: Include medical records, medications, and insurance cards. The National Cancer Institute recommends a kit with needed items (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature).
- Infection Prevention: Wash hands, avoid sick individuals, and ensure clean water and food (Coping with Cancer After a Natural Disaster: Frequently Asked Questions for Cancer Patients and Their Caregivers).
- Telemedicine Use: Leverage advances like the K-DiPS app (currently in Japanese) for medical information during disasters (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature).
A table summarizing patient needs and disaster effects, adapted from Kotronoulas et al. (2017), highlights key areas:
| Need Domain | Operational Definition | Potential Effects of Natural Hazards |
|---|---|---|
| Physical/cognitive | Symptom management, treatment toxicity, cognitive dysfunction | Disruption of medication, treatment, observation |
| Psychosocial/emotional | Help with depression, anxiety, fear | Additional stresses from disaster, loss, disruption |
| Family-related | Support for family relationships, caregiver participation | Potential separation from family, loss of support |
| Social/societal | Help with social isolation, diminished socialization | Increased isolation due to separation from social connections |
| Interpersonal/intimacy | Help with body image, sexuality, fertility issues | Exacerbation of intimacy issues due to stress, disruptions |
| Practical/daily living | Help with transportation, financial strain, daily tasks | Disruptions in all aspects of daily living |
| Information/education | Help with lack of information, uncertainty about self-care | Infrastructure disruption limiting access to information |
| Health system/patient-clinician communication | Help with insufficient communication, decision-making | Infrastructure disruption precluding healthcare contact |
Healthcare System Strategies
Healthcare providers and institutions can enhance resilience through:
- Disaster Planning: Develop coordinated plans with defined roles, clear procedures, and communication means, as suggested by Mensah et al. (2005) (Cancer Patients During and after Natural and Man-Made Disasters: A Systematic Review). Ensure surge capacity and business continuity plans (Cancer Patients During and after Natural and Man-Made Disasters: A Systematic Review).
- Telemedicine and Technology: Use telemedicine for continuity, with backup electronic health records to mitigate power failures (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature).
- Staff Training: Educate clinicians on disaster response, focusing on cancer patient needs (Cancer Patients During and after Natural and Man-Made Disasters: A Systematic Review).
- Resource Allocation: Apply cancer-specific resource-stratified guidelines, especially in low- and middle-income countries (LMCs), to ensure equitable care (Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care).
- Community Collaboration: Partner with agencies like the Red Cross for shelter support and prioritize cancer patients in relief efforts (Coping with Cancer After a Natural Disaster: Frequently Asked Questions for Cancer Patients and Their Caregivers).
Global and Regional Perspectives
Asia, with 60% of the global population, faces significant disaster vulnerability, contributing to nearly half of new cancer cases and over half of cancer deaths (Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care). Countries like Japan, India, and the Philippines have initiated national plans, aligning with frameworks like the Sendai Framework for Disaster Risk Reduction 2015-2030 (Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care). Oncology societies can play a role in training, protocol development, and research support (Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care).
Research Gaps and Future Directions
Despite growing evidence, gaps remain, particularly in low- and middle-income settings, aging populations, and implementation barriers like funding and infrastructure (Maintaining quality of life and care for cancer survivors experiencing disaster disruptions: a review of the literature). Future research should focus on long-term follow-up studies, quality-of-life endpoints, and integrating cancer care into disaster planning.
Natural disasters pose significant risks to cancer care, but with proactive preparedness and coordinated efforts, disruptions can be minimized. Patients should prioritize emergency planning and infection prevention, while healthcare systems must enhance resilience through technology, training, and community collaboration. By addressing these challenges, we can better protect cancer patients and ensure continuity of care during crises.
Key Points

Introduction to the Issue
Natural disasters can severely impact cancer care, creating barriers for patients who rely on continuous treatment. These events, such as hurricanes or earthquakes, can damage healthcare facilities, disrupt supply chains, and force evacuations, all of which complicate access to critical care. For cancer patients, delays in treatment can have serious consequences, potentially lowering survival rates for conditions like breast or colorectal cancer.
Challenges During Disasters
Cancer patients often face unique challenges during natural disasters:
- Access to Treatment: Facilities may be destroyed or inaccessible, leading to delays in chemotherapy, radiotherapy, or surgery.
- Medication Disruptions: Patients may struggle to refill prescriptions, risking health complications if treatments are interrupted.
- Increased Health Risks: Shelters can expose immunocompromised patients to infections, exacerbating their condition.
- Psychological Stress: The trauma of displacement can worsen anxiety and depression, affecting treatment adherence.
Strategies for Protection
To reduce disruptions, both patients and healthcare systems can take proactive steps:
- Patient Preparedness: Create an emergency kit with medical records, medications, and contact information. Discuss disaster plans with healthcare providers to ensure continuity.
- Healthcare System Readiness: Develop disaster response plans, use telemedicine for remote consultations, and train staff to handle cancer patients’ needs during crises.
- Community Support: Collaborate with local agencies to provide shelters with healthcare access and prioritize cancer patients in disaster relief efforts.
