The meaning of the word survivor may even be culturally linked to the population of veterans who have survived a life-threatening combat experience. More research is needed to understand the veteran cancer survivorship experience. The meaning of survivorship must be explored with each veteran, as it may influence his or her adherence to a survivorship plan of care.
Veterans make up a unique subset of cancer survivors, in part because of risk factors associated with their service. Many veterans developed cancer as a result of their military exposure to toxic chemicals and radiation. To date, VA recognizes that chronic B-cell leukemias, Hodgkin disease, multiple myeloma, non-Hodgkin lymphomas, prostate cancer, respiratory cancers, and soft tissue sarcomas are all presumptive diseases related to Agent Orange exposure. 13 There are other substances also presumed to increase the risk of certain cancers in veterans who have had ionizing radiation exposure. 14 There is still much to learn regarding veterans who served during the Gulf War, Operation Enduring Freedom, and Operation Iraqi Freedom. 15,16
In a comparison of VA data files with U.S. SEER data files from 2007, researchers identified differences in characteristics between veteran cancer survivors and civilian cancer survivors. 17 In addition to increased exposure risks, the veteran cancer survivor population is older than the general cancer survivorship population and is mostly male. 17 Veterans’ comorbid conditions, such as type 2 diabetes, ischemic heart disease, Parkinson disease, and peripheral neuropathy, which may be service related, complicate survivorship. 17 These characteristics (age, gender, exposure risks, and comorbid conditions) influence the type of cancer diagnosed and treatment options, and they may ultimately impact survivorship needs
(Table 1).
The prevalence of mental health issues in the veteran population is significant. 18 Posttraumatic stress disorder affects 7% to 8% of the general population at some point during their lifetime and as many as 16% of those returning from military deployment. 19 In a predominantly
male veteran study correlating combat PTSD with cancerrelated PTSD, about half the participants (n = 170) met PTSD Criterion A, viewing their cancer as a traumatic experience. 20 Posttraumatic stress disorder, depression, anxiety, and addictive disease all must be addressed in the survivorship plan of care.
Poor mental health has been linked to increased morbidity and mortality and can limit the veteran’s ability to participate in health promotion and medical care. 21 Distress related to cancer is well recognized in the civilian population. 22,23 Veterans are at risk for moderate-tosevere disabling distress, especially when the cancer is associated with their military service. Vietnam veterans who have a diagnosis of cancer report that they have already served their time and are now serving it again, having to wage a battle on cancer and undergo difficult treatments and associated adverse effects (AEs). 24 It is important to note, however, that some veterans have developed strong coping skills, which gives them strength and resilience for the survivorship experience. 25
Other factors also contribute to veterans’ unique survivorship needs. Many veterans have limited social and/or economic resources, making it difficult to receive cancer treatment and follow recommendations for a healthful lifestyle as a cancer survivor. Demographics from the VA have illustrated that many veterans have a limited support system (65% do not have a spouse), and many have low incomes. 26 Although veterans comprise about 11% of the general population, they make up 26% of the homeless population. 26 It is estimated that 260,000 veterans are homeless at some time during the course of a year, and of these, 45% have mental health issues and 70% have substance abuse problems. 27 Basic needs such as housing, running water, heat and electricity, and nutrition must be met in order to prevent infection during treatment, maximize the benefit, and reduce the risks associated with treatment. Transportation issues can make it challenging to travel to medical centers for cancer surveillance following treatment.
