Post-Traumatic Stress Disorder in Cancer Caregivers: A Silent Epidemic?

Every year, millions of people care for loved ones facing cancer. This places a substantial psychological burden not only on patients but also on family members and friends providing care. A newly published scientific review found that more than 15% of adults caring for people with cancer develop post-traumatic stress disorder (PTSD). Among caregivers of patients with head and neck cancers or acute leukemia, the rate can reach 37%!

Published on March 14, 2025, in Archives of Gerontology and Geriatrics Plus, this striking study sheds light on the mental health of an often invisible but crucial group in cancer care: caregivers.

Caregivers Are Still Overlooked in Psychosocial Oncology

Relatives of people receiving cancer treatment stand beside their loved ones through demanding caregiving that may last months or even years. Yet they often receive insufficient support from psychosocial oncology services. The study's lead author, social worker Elizaveta Klekovkina, says:

“Caregivers remain largely overlooked in psychosocial oncology, and many do not receive the support they need.”

Post-Traumatic Stress Disorder (PTSD): An Invisible Burden

Researchers analyzed 23 studies examining post-traumatic stress symptoms in adults caring for people with cancer. Most were limited by small sample sizes, and a lack of racial and gender diversity among participants.

The findings are striking:

• Among cancer caregivers, more than 15%meet PTSD criteria.

• For those caring for patients with head and neck cancer or acute leukemia, the rate rises as high as 37% in these groups.

• The most common symptoms are intrusive thoughts (flashbacks) and heightened alertness (hypervigilance).

• Unlike other traumatic situations, however, avoidance is almost impossible for caregivers: they remain involved in caring for the patient and cannot disengage.

What Factors Increase PTSD Risk?

The review also identified various individual and patient-related factors that increase the risk of developing PTSD:

• Pre-existing mental health problems (depression, anxiety, etc.)

• Limited social support

• A heavy caregiving burden

• Factors related to the patient's condition:

  • Severity of illness

  • Symptom burden

  • Perceived likelihood of death

Study coauthor and social worker Maya Stern emphasizes:

“Identifying these risk factors allows us to develop targeted interventions to prevent and reduce traumatic stress in caregivers.”

Long-Term Effects of Trauma and an Urgent Need for Research

The study highlights an important gap: research in this area is both scarce and methodologically limited. This hinders the development of preventive, evidence-based approaches to caregivers' mental health.

Study coauthor Dr. Carmine Malfitano states:

“We were surprised to find so few studies on traumatic stress among caregivers of adults with cancer. New research is urgently needed to close this gap in the literature and integrate caregiver support into oncology services.”

Early Intervention Is Vital: Screening Must Become Proactive

The study also emphasizes that overlooking traumatic stress in caregivers can harm both mental and physical health in the long term. Particularly at turning points such as cancer diagnosis, recurrence, or treatment transitions, early intervention and support programs are vital.

Professor Esme Fuller-Thomson, one of the study's senior authors, summarizes:

“The high prevalence of PTSD among caregivers of adults with cancer shows that these individuals need early support from the time of diagnosis.”

Conclusion: Cancer Affects the Whole Family, Not Just the Patient

This comprehensive study makes an important appeal to the oncology community: Facing cancer is a psychosocial struggle as well as a medical one. Protecting caregivers alongside patients is essential. Preventing serious mental health conditions such as PTSD requires greater investment in screening, early intervention, and psychosocial support programs.
