Challenges encountered by patients with cancer
The effects of cancer on patients and survivors are always complex and subtle and can be interpreted from two perspectives: time and function. Patients’ and survivors’ long interactions with cancer are roughly divided into multiple stages: pre-diagnosis, post-diagnosis before treatment, short-term after treatment, and long-term after treatment.8 Different stages entail different problems and demands. Regarding the functional domains, cancer results in challenges at the individual level, such as somatic problems, psychological distress, and questioning about spirit and existentialism3; and at the interpersonal and social levels, such as the deterioration of social functioning and relationships.9
Deterioration of self-concept
Self-concept is a complex notion that comprises several components. Psycho-oncology research has examined the following subconcepts: self-esteem, body image, self-discontent and self-appraisal.8
Self–cancer interaction, which refers to the interaction between an individual’s fluctuation of self-concept and the whole process of cancer, is a bidirectional relationship. On the one hand, in the 1990s, researchers stated that cancer not only causes physical pain but may also undermine patients’ self-concept. As a chronic disease, some typical aspects of cancer (eg, uncertainty) and cancer treatments (eg, aggressive physical damage) cause patients and survivors to be especially vulnerable to changes in their self-perceptions.10 On the other hand, self-concept was proven to be a dependent and independent variable of the development and progression of cancer, the outcome of cancer treatment, and the adjustment to the illness. For example, low self-esteem is negatively related to social functioning, inducing a reciprocal decrease in self-esteem.8
To investigate further, the change in self-discrepancy, which refers to the gap between one’s actual self and ideal self,11 is a critical dimension for understanding self-concept in psycho-oncology. For example, a study found that patients with cancer who exhibited more physical symptoms, had worse health, and perceived their cancer as a chronic rather than an acute disease had higher self-discrepancies. Conversely, low levels of self-discrepancy were correlated with higher life purpose, more positive relationships with others and fewer depressive symptoms.12
However, cancer can reconstruct one’s self concept in various ways. A qualitative study investigating 26 adolescents and young adult cancer survivors found that 15 regarded cancer as ‘part of the past’, while another 5 said the ‘cancer survivors’ identity rarely influenced how they defined themselves in daily life.13 Therefore, cancer patients’ and survivors’ self-perceptions should be understood case-by-case in clinical circumstances.
Body image disturbance
Body image is a direct personal perception and appraisal of one’s appearance; thus, body image dissatisfaction may result in severely distorted psychosocial well‐being.14 Cancer may profoundly change a patient’s body appearance and function15 during the different treatment stages because of, for instance, surgical interventions, chemotherapy, radiotherapy and drug use.16 This could result in scarring, hair loss, body shape alteration, and other temporary or permanent consequences.17 Fear of change in one's body image begins before surgery or other treatments.18 Excess concern about this change is detrimental to patients’ quality of life and may result in depression, anxiety and overall psychological distress.18 19
Although body image issues affect an array of patients with cancer15, the most typical and subtle cohorts, such as those with head and neck cancer and female patients with breast cancer, have attracted the most attention in previous research. For example, one study stated that the perceptions of female patients regarding the loss of their breasts were filled with contradictions, tension and uncertainties while negotiating the discrepancy between self, the body, and societal expectations and perceptions of femininity and womanhood.17
Sexual trouble
Sexual dysfunction is one of the most common causes of distress among patients with cancer.20 It negatively affects the quality of life and, in some instances, is the most difficult aspect for patients with cancer.21
Cancer patients and survivors may face sexual problems regardless of the cancer type or treatment.22 A recent study showed that one-third of adolescent and young cancer patients and survivors reported being dissatisfied with their sexuality, feeling less intimacy and having supportive care needs in this area.21 Another integrated study using both qualitative and quantitative methods reported that sexual frequency, sexual satisfaction, and engagement in penetrative and non-penetrative sexual activities were reduced after cancer in both men and women.23 Today, oncologists attribute sexual problems to physical factors, such as the disease and its treatment, as well as other psychological and social factors, such as interpersonal, religious and cultural influences.22 For example, a Brazilian study of patients with breast cancer reported that in traditional gender cultures where the female body is linked with youth and feminine sexual attractiveness is highly valued, some patients found themselves beautiful but sexually unattractive.24
Unfortunately, many cancer patients and survivors are not prepared for potential sexual changes and do not receive the needed information and support.20 22 A survey of 2657 cancer patients and survivors in the Netherlands indicated that 65% of the respondents needed information about sexuality.22 Clinical practitioners should note that support for sexual issues needs to be addressed, even when the patients do not have reproduction-related (breast, gynaecological and male reproductive organs) types of cancer.21
Maintaining social relationships
For young, single patients, cancer delayed the initiation of romantic relationships.25 Moreover, the marriage rate of such patients was lower than that of their siblings and the general population.26 As for married people, studies showed mixed results of how cancer influences intimate relationships. According to Swensen et al,27 couples affected by cancer expressed more love to each other after the diagnosis than healthy couples. However, marriage problems for both groups did not differ. The couples affected by cancer were found to be less committed to each other after the diagnosis. Other studies indicate that cancer may induce marital distress and decrease the quality of the relationship.9 28 In a related survey, 13.1% of the respondents complained of facing difficulties in their marriage and sexual lives.9
Family relationships, especially those between patients and their caregivers, are significantly influenced by the physical and mental conditions of the patients. A study examining the family types of cancer patients, including the caregivers, found the functioning of the entire family changes because of the illness; most of the families affected by cancer showed a low expressiveness characteristic, followed by supportive and detached family types.29 In the general dimension of socialising, as cancer patients and survivors encounter challenges such as unemployment, social isolation and rehabilitation,30 they may experience other related problems, such as social constraints (avoidance and criticism) and cancer-related loneliness (feeling socially disconnected due to cancer).31
Emotional distress
Being considered a major life stressor, cancer may cause substantial psychological distress as well as mental health disorders.6 The most common mental health disorders include major depressive disorder, generalised anxiety disorder, adjustment disorder, panic disorder and post-traumatic stress disorder.32 A poor psychological state is always related to a less satisfying quality of life, decreased psychosocial functioning33 and a worse prognosis.34 Survivors with late effects (symptoms caused by advanced cancer) exhibited higher levels of psychological distress, somatisation and anxiety. Higher levels of depression are associated with femininity, not being in an intimate relationship and experiencing late effects.7
Many cancers are associated with shame and guilt. Some patients experience disease-related stigma. For example, lung cancer has been proven to be significantly correlated with smoking behaviour; consequently, patients with lung cancer are prone to developing self-stigma and thoughts of self-blame.34 Due to the nature of the illness, cancer patients and survivors often feel a self-perceived burden.35
A study in China found the prevalence of psychological distress accounted for 10.6% and 20.0% in healthy controls and patients with cancer, respectively.36 Another recently published survey showed that adolescents and young cancer survivors(people diagnosed with cancer when they were young) are more likely to experience psychological distress (11.5% of 1757) than adults with no history of cancer (5.8% of 5227), including 11.2% reporting distress more than 20 years after cancer diagnosis.6
Treatment-related problems
Among the stressors that cause emotional distress, treatment-related problems are exclusive to the medical field, especially in oncology. Based on qualitative and quantitative results, because of fear, individuals may either decide to undergo cancer screening or postpone their hospital visits to seek medical advice.37 38 Research shows that individuals facing the fear of breast cancer are more hesitant to go for screening. However, social support may be benefitial for making the decision to take screening.38
Fear of recurrence (FCR), often defined as ‘fear, worry or concern that cancer may recur or progress’,39 is another major challenge faced by patients and survivors. Whereas mild FCR may encourage adaptive health behaviours, severe FCR can result in depression, high levels of anxiety and preoccupation.40
Casual problems
In addition to treatment, problems experienced outside the hospital can be overwhelming. The economic burden of covering the cost of treatment and the maintainence of a satisfactory quality of life is a major problem for cancer patients and survivors.41 For example, managing related financial affairs, such as insurance, may present a huge challenge.
In many countries, the distribution of healthcare resources is imbalanced.30 This means patients may have to travel between cities to acquire the most accurate medical information, higher quality treatment, or specialized surgery conducted by experts. Arranging for transportation and accommodation in a distant city is another casual disturbance.
Prior to their cancer diagnosis, most patients had shouldered some of their families’ domestic responsibilities (eg, served as caregivers for elderly members or young children). Following the illness, filling the roles vacated by the patient becomes challenging. Before the illness, the patient may have been part of the workforce, but intense multimodal treatment may prolong the patient's period of unemployment.42 Many cancer patients who are able to work efficiently choose to return to work. According to a study of oral cavity cancer survivors, 55.2% returned to work after treatment, which positively influenced their post-treatment rehabilitation.43 However, inadequate support and communication, toxic work environments, discrimination, and negative perceptions of their work performance acted as barriers to the survivors’ rehabilitation.30
