About 30% of all cancer survivors and their caregivers have reported psychological distress, which encompasses diagnoses of depression, anxiety, and overwhelming stress. For both survivors and caregivers, psychological distress can negatively impact different aspects of treatment, care, and well-being. In fact, patients with lower levels of psychological distress have been shown to recover quicker, exhibit fewer symptoms, and even have lower mortality rates after treatment. 

When patients with cancer also suffer from psychiatric diagnoses, it can present unique challenges to healthcare professionals. Because oncology nurses build relationships with patients while addressing issues, understanding the obstacles to practice is key to providing the best possible care. By having a keen understanding of symptoms, assessment procedures, and necessary response skills, oncology nurses can work together with the mental health team to provide holistic care throughout the cancer journey. 

Nearly 20% of Americans experience mental illness in a given year, according to the National Alliance on Mental Illness. With diagnoses such as schizophrenia, bipolar disorder, or major depression, about one in every 25 Americans suffers from a serious mental illness that directly affects major life activities. The prevalence of mental illness in the United States can have a downstream effect on cancer care and patient outcomes, and with these statistics, oncology nurses may encounter patients with cancer who have pre-existing psychiatric disorders. Healthcare providers in fields outside of psychology need to be prepared to address the unique needs and individualized care required to support this patient population during and beyond cancer treatment. 

As the leading cause of death for adult Americans, cardiovascular disease is a complication found in many patients with cancer. Many cancer treatments have the potential to impact existing cardiac comorbidities or develop new cardiovascular conditions in patients undergoing treatment. Understanding and recognizing this issue is paramount for oncology nurses and is the focus of current research efforts impacting clinical practice. 

Polypharmacy is the use of several medications simultaneously for different medical conditions. Data confirm that polypharmacy is prevalent in older adults with cancer, with one study reporting a minimum of four prescriptions to define polypharmacy. Many medications prescribed during cancer care are intended to treat other comorbid conditions that occur prior to a patient’s cancer diagnosis (e.g., heart disease, hypertension, hyperlipidemia, reflux disease). Reportedly, one third of individuals older than 65 years use more than one pharmacy to fill prescription medications. This can lead to further confusion for patients regarding medication management.

Research has shown that women aged 65 and older who have breast cancer experience higher rates of heart failure compared to their age-matched counterparts, ranging from 29% of women with breast cancer who received no chemotherapy to 38% of women who received treatment with anthracyclines. However, little is known about the association between heart failure and long-term survival in older women with breast cancer, and it is unclear how the relative contribution of heart failure to mortality risk varies by breast cancer stage.

Taller men and those with a higher body mass index (BMI) may be at increased risk for high-grade prostate cancer and disease-related mortality, according to the results of a study published in BMC Medicine.

According to the results of a study published in the International Journal of Cancer, periodontal disease is associated with an increased risk of developing non-Hodgkin lymphoma.

More than ever before, oncology nurses are required to provide multifaceted care when it comes to managing patients with cancer. As the population of patients with cancer continues to age and cancer becomes more of a chronic condition, oncology nurses are seeing more patients who exhibit comorbidities during their cancer journey.
