Breast cancer, one of the most prevalent forms of cancer affecting women, has traditionally been associated with postmenopausal women, typically those aged 50 and above. However, recent shifts in lifestyle patterns and an increase in unhealthy habits have led to a concerning trend: younger women, including those of childbearing age, are now at an elevated risk of developing breast cancer.
For women diagnosed with breast cancer who have not yet completed their families, the prospect of future motherhood becomes a critical consideration. It's essential to address fertility preservation options before initiating cancer treatment to safeguard the possibility of having children in the future.
We spoke to Dr. Rucha Kaushik, Consultant Breast Cancer Surgeon at P.D. Hinduja Hospital & MRC about hoe breast cancer can impact your fertility.
Impact of Breast Cancer Treatment on Fertility
The treatment journey for breast cancer typically begins with surgery, especially in early-stage cases. Depending on the specific characteristics of the cancer, this may be followed by chemotherapy, radiotherapy (radiation), and hormone therapy. Each of these treatment modalities can have varying effects on a woman's fertility:Surgery
Surgical interventions for breast cancer, whether lumpectomy or mastectomy, do not directly impact a woman's reproductive capabilities. The ovaries and uterus remain unaffected, preserving the potential for future pregnancies.
Chemotherapy
Chemotherapy poses the most significant risk to fertility among breast cancer treatments. The powerful drugs used in chemotherapy can damage the ovaries, potentially leading to:
- Temporary or permanent cessation of menstrual periods
- Reduced ovarian reserve (number of viable eggs)
- Premature ovarian failure (early menopause)
- Women in their 30s: There's a relatively good chance of menstrual function returning after chemotherapy, with the possibility of natural conception remaining intact.
- Women in their 40s: The likelihood of regaining menstrual function post-chemotherapy is lower. For these women, discussing fertility preservation options before starting treatment is crucial.
Radiotherapy
While radiation therapy for breast cancer doesn't directly affect the reproductive organs, it's important to note that it's often administered following chemotherapy and before hormone therapy. The cumulative effect of these treatments can impact overall fertility.Hormone Therapy
For women with hormone-sensitive breast cancers, hormone therapy is a standard part of the treatment regimen. This therapy typically lasts 5 to 10 years, during which pregnancy is contraindicated due to potential harm to the developing fetus. After completing hormone therapy, women may pursue pregnancy, either naturally or through assisted reproductive technologies if they've preserved their eggs.Fertility Preservation Options
Specialized fertility preservation clinics offer invaluable services to women facing breast cancer treatment. These clinics provide:- Comprehensive counseling on fertility risks associated with cancer treatments
- Guidance on various fertility preservation methods
- Assistance in navigating the egg or embryo freezing process
• Egg freezing (oocyte cryopreservation): This involves stimulating the ovaries to produce multiple eggs, which are then retrieved and frozen for future use.
• Embryo freezing: Similar to egg freezing, but the eggs are fertilized with sperm before freezing, creating embryos.
• Ovarian tissue freezing: A portion of ovarian tissue is surgically removed and frozen, potentially allowing for reimplantation later.
Key Considerations for Women
1. Age at Diagnosis:- Women diagnosed in their 30s generally have a better prognosis for fertility recovery post-treatment.
- Women in their 40s should strongly consider fertility preservation before starting chemotherapy due to the higher risk of permanent ovarian failure.
2. Cancer Aggressiveness: Understanding the nature and aggressiveness of the cancer is crucial in making informed decisions about both treatment and fertility preservation.
3. Timeline: Fertility preservation procedures typically take 2-3 weeks, which may delay the start of cancer treatment. This timeline should be discussed with both the oncology and fertility teams.
4. Future Family Planning: Women should consider their desired family size and timeline for having children when making decisions about fertility preservation.
5. Financial Aspects: Fertility preservation can be costly, and insurance coverage varies. Some organizations offer financial assistance for cancer patients seeking fertility preservation.
6. Emotional Support: Coping with a cancer diagnosis while making decisions about future fertility can be emotionally challenging. Psychological support should be readily available.
