The World Health Organization defines sexual health as the physical, emotional, and mental state related to a person's gender (
1). Research has shown that certain diseases can exacerbate sexual problems (
2). Among these, breast cancer is notably prevalent among women and is the second leading cause of cancer-related deaths (
3). Mastectomy, a common treatment for breast cancer, involves removing the breast and often leads to sexual health consequences that require clinical attention (
4). The biopsychosocial perspective on sexual health goes beyond mere biological aspects, also considering the psychological factors associated with sexual well-being (
5). In recent years, there has been significant research into people's perceptions of sex and related issues. Sexual distress, an important aspect of sexual health (
6), involves experiencing negative emotions such as anxiety, worry, feelings of failure, and inadequacy during sexual experiences, which can adversely impact one's quality of life (
7). Therefore, it is crucial to study the factors contributing to sexual distress, as understanding these can help develop effective interventions to improve sexual health (
7).
In addition to the side effects of mastectomy, survivors often experience various emotional problems after surgery. A study conducted in Iran involving 82 breast cancer patients at Razi Hospital in Rasht, who underwent radiotherapy, found that 32 (39%) suffered from severe mental health issues (
8). These emotional difficulties are linked to worsening sexual problems and increased sexual distress (
2). Unlike medical conditions such as diabetes, hypertension, and heart disease, which are not typically associated with sexual distress in women (
9), emotional issues significantly contribute to sexual problems in women (
10). Moreover, after a mastectomy, many women feel uncomfortable with the changes in their appearance (
11). Since women often place a high value on their appearance (
12), they usually experience greater psychological distress when dealing with diseases that alter their appearance (
11). Indeed, breast cancer and breast surgeries are associated with feelings of lost attractiveness, diminished femininity, and bodily imperfections (
13), which are linked to increased distress and sexual problems in women (
14). The significant role of body image has been emphasized in recent years, leading researchers to develop tools for measuring and evaluating patients' perceptions of changes in their physical appearance (
15). Awareness of one's body is influenced by a non-judgmental attitude toward failures, known as self-compassion. Self-compassion involves caring for oneself, adopting a non-judgmental perspective, and demonstrating empathy during times of suffering (
16). It is associated with less suffering, better mental health, and higher life satisfaction (
17). Additionally, self-compassion plays a crucial role in reducing sexual distress and enhancing sexual satisfaction in women (
18).
In a study conducted by Michael et al., the results indicated that both self-compassion and damaged body image were associated with higher levels of sexual distress in cancer patients. Thus, as self-compassion decreased and damaged body image increased, the level of sexual distress also increased (
6). Fischer et al. found that difficulties in emotion regulation were associated with lower sexual health, problems in the sexual cycle, and reduced sexual satisfaction (
19). Additionally, a study by Yousaf et al. demonstrated that body image and self-compassion significantly predicted sexual distress in women after mastectomy (
14).
A better understanding of the causes and factors associated with sexual distress may assist therapists in designing appropriate treatments for these patients. In a study conducted in Iran by Bagheri-Sheykhangafshe et al., results showed that a self-compassion-based treatment led to significant improvement in sexual function in MS patients (
20). Another study by Fischer et al. indicated that internet-based therapy focusing on emotion regulation could improve sexual health in various aspects (
21). Despite these findings, the studies had significant limitations, including a small sample size of mastectomy patients and sample selection based solely on breast cancer, without consideration of the type of surgery. Another important challenge was the culturally based nature of self-compassion, which is influenced by cultural values. This issue has significant implications because the results from one society cannot necessarily be generalized to another. Furthermore, these studies have inadequately focused on the role of mediators and have seldom used structural equation modeling from an analytical perspective.
