Vaginal dryness: a common but taboo symptom resulting from breast cancer treatment

More than half of all women experience vaginal atrophy, including vaginal dryness, after natural menopause.1 Unfortunately, for women with breast cancer, this figure can go as high as 70%.2

During the breast cancer journey, your intimacy may fall victim to physical changes, such as a mastectomy or an axillary lymph node dissection for certain women. But vaginal dryness can also result from breast cancer treatment.2

How does vaginal dryness come about?

Vaginal dryness can result from natural menopause but can also stem from decreased levels of circulating oestrogen due to breast cancer treatments.2,3 These treatments include chemotherapy or endocrine (hormonal) therapy. This drop in oestrogen levels, as a result, leads to a decreased stimulation of vaginal receptors, causing membranes in the vagina to become thinner, less flexible, and produce less lubricating fluid.3

What are the symptoms of vaginal dryness?4

Breaking the taboo and promoting a discussion on vaginal health

Doctors are human too and may avoid bringing topics such as this given its sexual nature. And even if they do not mind having a discussion such as this, research suggests that they prefer to focus on combatting the disease.1 The best piece of advice is to take charge of the situation when it comes to improving your intimacy and proactively bring this subject up with your doctor.
