Dyspareunia After Cancer Treatment: Causes and Solutions
Pain during intercourse affects a significant proportion of women following treatment for gynaecological cancers — and is one of the most under-addressed quality-of-life issues in oncology follow-up. Studies show that 40–60% of women experience dyspareunia or sexual dysfunction after treatment for cervical, endometrial, ovarian, vulvar, or vaginal cancers. Yet many women do not raise it with their oncologist, and many healthcare providers do not proactively assess it.
Causes After Surgical Treatment
Following hysterectomy, particularly radical hysterectomy for cervical cancer, the vaginal vault may be shortened and the upper vagina can feel rigid due to scar tissue formation. Loss of uterine support changes the anatomy of pelvic floor function. Nerve-sparing techniques at surgery reduce but do not entirely eliminate these effects.
Causes After Radiotherapy
Pelvic radiotherapy causes the most significant long-term vaginal changes. Radiation fibrosis progressively stiffens vaginal tissue. Radiation to the ovaries causes premature menopause and severe vaginal atrophy. Vaginal stenosis — narrowing of the vaginal canal — can develop over months to years after radiotherapy and makes intercourse painful or impossible without treatment. Regular vaginal dilator therapy, started early after radiotherapy, is the primary preventive intervention.
Treatment Approaches
- Topical vaginal oestrogen — creams, pessaries, or rings delivering local oestrogen; reverse atrophy and improve vaginal moisture without significant systemic absorption; safe even after oestrogen-sensitive cancers in most guidelines
- Non-hormonal vaginal moisturisers and lubricants — used regularly (not just at intercourse) to maintain vaginal tissue health
- Vaginal dilator therapy — graduated dilators used 3–5 times per week to prevent stenosis after radiotherapy; most effective when started early
- Pelvic floor physiotherapy — addresses hypertonic (over-tight) pelvic floor muscles contributing to dyspareunia; highly effective
- Ospemifene — oral selective oestrogen receptor modulator for dyspareunia; used when topical treatment is not feasible
