Sexual Health, Quality of Life, and Fertility Counselling in Breast Cancer Survivors Younger than 40 Years.

Background and Objectives: Young women treated for breast cancer often face persistent sexual and reproductive challenges post-treatment, which frequently remain unaddressed during routine follow-up. This study evaluated health-related quality of life (HRQoL), sexual health, and fertility-related counselling in breast cancer survivors younger than 40 years. Materials and Methods: We performed a single-centre cross-sectional study including 65 women with non-metastatic breast cancer (at least 12 months post-primary treatment). Patients completed the EORTC QLQ-C30 and SHQ-22 questionnaires, along with a pilot-tested 7-item fertility preservation survey. Data were analyzed using descriptive statistics and non-parametric tests to compare treatment subgroups (e.g., endocrine therapy vs. others). Results: Overall quality-of-life scores were relatively preserved (median 66.67), with high functional scores. However, patients reported symptomatic distress, particularly fatigue and insomnia (both median 33.33). Sexual health was significantly impacted: communication with healthcare professionals was the most impaired domain (median score 100), followed by low libido (66.7) and vaginal dryness (66.7). Women receiving endocrine therapy reported significantly lower functional scores and a higher symptom burden compared to those not on endocrine treatment (p < 0.05). While 60% of patients received fertility information, only 16.9% underwent preservation procedures. Notably, a significant association was observed between reproductive health actions and sexual behaviour; women who had undergone fertility preservation procedures reported higher levels of sexual activity (p = 0.015). Conclusions: Despite relatively preserved functional status, young breast cancer survivors face significant symptomatic and sexual challenges. The profound lack of communication regarding sexual health and the gaps in fertility counselling highlight the need for a more integrative, multidisciplinary approach in survivorship care.
