Hormone therapy is transforming the treatment of breast cancer across the Maghreb. With 50.3% of Moroccan patients and 49.3% of Tunisian patients benefiting from it, this “anti-hormone” therapeutic approach is reshaping the outlook for thousands of women facing hormone-dependent breast cancer.
Understanding hormone therapy: a groundbreaking principle
When hormones feed the cancer
Around two thirds of breast cancers are hormone-dependent. In these cases, the cancer cells carry oestrogen and progesterone receptors. The more numerous these receptors, the more the tumour feeds on these hormones to grow rapidly.
Hormone therapy acts as a protective shield. It blocks the stimulating action of the female hormones on the malignant cells, thereby slowing their progression.
Important: The pathological examination of the biopsies reveals whether your cancer expresses these all-important hormone receptors.
Two complementary approaches
Hormone therapy comes in two main strategies:
- Systemic drug treatment: acts on the entire body
- Ovarian suppression: surgical (oophorectomy) or through radiotherapy
When is hormone therapy prescribed?
A tailored, long-term treatment
This therapy generally accompanies surgery or other treatments. Prescribed for at least five years, it aims to:
- Reduce local recurrences in the operated breast
- Prevent the appearance of metastases
- Stabilise the disease in cases of metastatic cancer
In Tunisia, women treated with hormone therapy show significantly better survival: 86.6% compared with 73.1% for those who do not receive it.

Neoadjuvant hormone therapy: shrinking before operating
Sometimes treatment comes before surgery. This neoadjuvant approach makes it possible to reduce the size of the tumour and to consider breast-conserving surgery rather than a mastectomy.
Caution: Unlike conventional hormone treatments, anti-cancer hormone therapy requires stopping the pill and menopause hormone replacement therapy.
The leading drugs in hormone therapy
Anti-oestrogens: tamoxifen leads the way
Tamoxifen remains the gold standard for pre-menopausal women. This molecule blocks the oestrogen receptors, depriving the cancer cells of their hormonal fuel.
Proven effectiveness:
- A 42% reduction in recurrences
- Improved 5-year survival, with a 32% drop in mortality
In Morocco, tamoxifen is available at 124.30 dirhams for a box of 30 tablets, making this treatment accessible to many patients.
Side effects to anticipate:
- Hot flushes (in 40% of cases)
- Nausea and vomiting
- Joint and muscle pain
- Temporary oedema
Aromatase inhibitors: for post-menopausal women
Letrozole and anastrozole are the treatment of choice after menopause. These drugs block the production of oestrogen by the enzyme aromatase.
Points to watch:
- Vaginal dryness
- Joint pain in the wrists
- A risk of osteoporosis requiring monitoring
LH-RH analogues: reversible chemical castration
For younger women, goserelin and leuprorelin artificially mimic menopause. This “chemical castration” remains reversible within four weeks of stopping.
Monitoring required: These treatments bring on temporary menopausal effects but call for attentive medical follow-up.
| Treatment | For whom | Main side effect |
|---|---|---|
| Tamoxifen | Pre-menopausal women | Hot flushes (in 40% of cases) |
| Letrozole, anastrozole (aromatase inhibitors) | Post-menopausal women | Vaginal dryness, joint pain |
| Goserelin, leuprorelin (LH-RH analogues) | Younger women | Temporary menopausal effects |
Side effects: navigating them safely
Managing the discomforts day to day
Hormone therapy comes with side effects that vary from one woman to another. Even so, there are solutions for every situation:
Gynaecological complications: regular ultrasound monitoring of the uterus Clotting disorders: particular vigilance in women at thromboembolic risk Weight gain: often linked to stress and other treatments
Diabetes and hormone therapy: a particular vigilance
The risk of diabetes rises appreciably in the two years following diagnosis. Tamoxifen can contribute to disturbances in glucose regulation, calling for regular blood-sugar monitoring.
Soy: a promising natural ally
Isoflavones: natural protection from Asia
Studies show that Asian women have lower rates of breast cancer, thanks in part to their high consumption of soy. Isoflavones compete with the body’s own oestrogens, playing a protective role.
Optimal protection: The benefit is seen above all in women with a high intake before menopause, halving the risk.
Important: This consumption must begin as early as adolescence and continue over time to be effective.
Hormone therapy in the Maghreb: challenges and hopes
Accessibility and availability of treatments
Despite the progress, access to medicines sometimes remains problematic. In Algeria, frequent shortages of hormone therapy force some patients to interrupt their treatment, reducing their chances of recovery.
In Morocco, with 82% of patients receiving hormone therapy, access is gradually improving, though efforts are still needed for full coverage.
Personalised follow-up and a multidisciplinary approach
Hormone therapy requires rigorous medical follow-up. In Tunisia, the multidisciplinary approach makes it possible to adapt the treatment to each patient’s profile, optimising the results.
The choice between tamoxifen, aromatase inhibitors or LH-RH analogues depends on:
- The patient’s age
- Her menopausal status
- The presence of hormone receptors
- Her medical history
Looking ahead: towards personalised medicine
Hormone therapy for breast cancer is constantly evolving. Genetic tests now make it possible to identify the patients who will benefit most from these treatments, paving the way for precision medicine.
In the Maghreb, better access to care, the training of healthcare professionals and patient awareness are the keys to a more promising future. Every woman deserves to benefit from the therapeutic advances that can transform her prognosis and preserve her quality of life.
Hormone therapy today represents a tangible hope for thousands of women. With suitable follow-up and comprehensive care, it makes it possible to face the future with confidence while preserving their femininity.
