Is low libido a common symptom of Breast Cancer? What causes it and how can it be managed?

Low libido is common during and after breast cancer treatment, and it can arise from both physical and emotional factors. ^[1] Many people notice decreased desire during chemotherapy and with hormone-blocking therapies, and this often improves when vaginal dryness and pain are treated. ^{[2] [1]}

How breast cancer and its treatments affect sexual desire

• Chemotherapy and abrupt menopause: Chemotherapy can lower desire directly and may trigger ovarian failure, leading to sudden menopause with hot flashes, vaginal dryness, and pain with sex all of which reduce libido. ^{[2] [3]} Treating dryness and pain often leads to better arousal and desire. ^[1]
• Endocrine (hormone) therapy: Drugs that block estrogen (such as aromatase inhibitors or tamoxifen) reduce estrogen levels, causing vulvovaginal dryness, atrophy, and painful intercourse, which commonly lowers sexual interest. ^[4] These hormone-blocking drugs can bring on early menopause with sexual and vaginal health problems. ^[5]
• Body image and emotional health: Changes after surgery or reconstruction and the stress of cancer can affect sexual self‑esteem and desire. ^[5] Support programs that address intimacy and emotional challenges are available and can help. ^[6]

Common causes summarized

• Hormonal changes: Estrogen drop from treatment causing dryness and discomfort. ^[4]
• Pain and dryness: Vaginal atrophy and dyspareunia (painful sex) reduce desire. ^[1]
• Chemotherapy effects: Direct decrease in desire during treatment. ^[2]
• Psychological factors: Anxiety, mood changes, and body image concerns. ^[5]
• Medication side effects: Long‑term endocrine therapy can contribute to persistent symptoms. ^[4]

What you can do: practical management

• Talk with your care team: Discuss symptoms early; tailored strategies can improve comfort and desire. ^[2]
• Lubricants and moisturizers: Use water‑based lubricants (e.g., K‑Y, Astroglide) during sex and vaginal moisturizers regularly to reduce friction and pain. ^[7]
• Adjust sexual routines: Longer foreplay, trying different positions, and open communication with your partner can reduce discomfort and increase arousal. ^[7]
• Specialist support: Dedicated female sexual medicine programs offer comprehensive care for physical and emotional concerns affecting sex. ^{[4] [6]}
• Address dryness first: Improving vaginal comfort often improves desire and ability to reach orgasm. ^[1]

When first‑line measures aren’t enough

If non‑hormonal options don’t relieve severe vaginal atrophy and pain, local treatments may be considered after careful discussion of risks and benefits with your oncology team; systemic estrogen is generally avoided in estrogen‑dependent breast cancer. [PM18] Non‑pharmacologic and psychosocial approaches (education, counseling, pelvic floor therapy, and sexual aids) are often helpful and carry low risk. [PM18]

Partner communication and emotional care

Open conversation about worries such as fear of pain or changes in desire can reduce anxiety and improve intimacy. ^[2] Programs focused on intimacy after cancer can help with body image, confidence, and relationship dynamics. ^{[6] [5]}
