Breast cancer is one of the most common cancers affecting women globally, and Thrissur, Kerala, is no exception. Among the various treatment modalities available, hormone therapy (endocrine therapy) plays a crucial role in managing hormone receptor-positive breast cancer. This treatment targets the cancer’s growth mechanism by interfering with hormones such as estrogen and progesterone, which can fuel tumor progression.
At Dr. Bibin Francis Oncology, patients in Thrissur receive personalized and evidence-based hormone therapy as part of a comprehensive cancer care plan, focusing on both efficacy and quality of life.
Understanding Hormone Therapy in Breast Cancer
Hormone therapy works by blocking or reducing the production of hormones that stimulate the growth of certain types of breast cancer cells. It is primarily used for hormone receptor-positive breast cancers, where tumor cells have receptors for estrogen (ER) and/or progesterone (PR).
Unlike chemotherapy, hormone therapy is targeted and generally less invasive, making it suitable for long-term use, often spanning 5–10 years after surgery to prevent recurrence.
Why Hormone Therapy is Important
Helps prevent cancer recurrence after surgery or radiation
May be used before surgery (neoadjuvant) to shrink tumors
Improves overall survival in hormone receptor-positive patients
Can be combined with other treatments, such as chemotherapy or targeted therapy, for enhanced outcomes
Types of Hormone Therapy
Selective Estrogen Receptor Modulators (SERMs)
Example: Tamoxifen
Works by blocking estrogen receptors on cancer cells, preventing them from using estrogen to grow.
Often recommended for pre- and postmenopausal women.
Aromatase Inhibitors (AIs)
Examples: Letrozole, Anastrozole, Exemestane
Lower estrogen levels by inhibiting the enzyme aromatase, which converts androgens into estrogen.
Primarily used in postmenopausal women.
Ovarian Suppression
Achieved with GnRH agonists or surgical removal of ovaries
Reduces estrogen production in premenopausal women
Often combined with Tamoxifen or AIs for maximum effect
Estrogen Receptor Downregulators (ERDs)
Example: Fulvestrant
Degrades estrogen receptors, making them unable to stimulate cancer growth
Combination Therapies
Hormone therapy can be combined with targeted therapies like CDK4/6 inhibitors for advanced breast cancer
How Hormone Therapy is Administered
Oral medications: Most hormone therapies, like Tamoxifen or Aromatase Inhibitors, are taken as tablets daily.
Injection: Drugs like Fulvestrant are administered via intramuscular injections.
Duration: Typically prescribed for 5–10 years, depending on cancer stage, recurrence risk, and menopausal status.
Dr. Bibin Francis ensures that the therapy plan is tailored to individual patients, monitoring response and adjusting treatment as needed to achieve the best outcomes.
Benefits of Hormone Therapy
Prevents Recurrence: Significantly lowers the risk of cancer returning after surgery
Long-Term Protection: Offers ongoing cancer suppression over years of therapy
Fewer Side Effects: Compared to chemotherapy, hormone therapy is generally better tolerated
Combination Potential: Can be combined with targeted therapy for advanced-stage cancers
Outpatient-Friendly: Most therapies can be taken at home without hospitalization
Managing Side Effects of Hormone Therapy
Although generally safer than chemotherapy, hormone therapy can cause side effects, which Dr. Bibin Francis helps manage carefully:
| Side Effect | Description | Management Tips |
|---|---|---|
| Hot Flashes | Sudden warmth, sweating, or flushing | Lifestyle changes, cooling techniques, medications if needed |
| Fatigue | Persistent tiredness | Regular light exercise, rest, balanced diet |
| Bone Loss | Reduced bone density (risk of fractures) | Calcium & Vitamin D supplements, bone density monitoring |
| Mood Changes | Anxiety, irritability, depression | Counseling, stress management, medications if necessary |
| Weight Changes | Mild weight gain | Diet and exercise regimen |
| Vaginal Dryness | Discomfort during intimacy | Moisturizers, lubricants, medical advice |
| Blood Clots | Rare, mainly with Tamoxifen | Regular checkups, prompt reporting of symptoms |
Who Should Consider Hormone Therapy?
Hormone therapy is suitable for patients whose tumors are ER-positive and/or PR-positive.
It may be recommended:
After surgery to prevent recurrence
Before surgery to reduce tumor size (neoadjuvant therapy)
For metastatic breast cancer to control progression
In combination with targeted therapy for advanced disease
Dr. Bibin Francis evaluates each patient carefully, using genetic testing, tumor markers, and imaging to design an optimal, personalized therapy plan.
Hormone Therapy and Lifestyle
Complementary lifestyle measures can enhance the effectiveness of hormone therapy:
Balanced Diet: Focus on fruits, vegetables, lean proteins, and low saturated fats
Regular Exercise: Helps maintain weight, reduces fatigue, and strengthens bones
Avoid Smoking & Alcohol: Both can negatively affect hormone levels
Routine Follow-Up: Regular blood tests, imaging, and checkups for early detection of recurrence
