Are non-hormonal treatments safe in breast cancer?

Question

Hello doctor,

I am a 41-year-old female recently diagnosed with metastatic breast cancer, and I have been feeling overwhelmed with worry and uncertainty about the future. I am on chemotherapy and targeted therapy right now, but I still have so many questions about my women’s health and fertility possibilities.

One of my big concerns is fertility because I do not have children yet. I wonder if there is still a chance to preserve fertility at this stage, or if the therapies I have already undergone might have reduced those chances. I am also wondering if it would be okay to try to get pregnant in the future, or if that would increase the danger of the cancer coming back.

I have also been having menopausal symptoms, such as hot flashes and irregular cycles, because of my cancer treatments.

Are there non-hormonal, safe, and effective ways to manage these symptoms without making my situation worse?
I would also like some contraception advice. Is an IUD safe for me, or should I choose a non-hormonal method?

Lastly, I would like to learn more about whether cancer treatments can lead to permanent infertility and how to cope emotionally with the effects that these changes may have on my life and plans.

Please help.

Thank you for your guidance.

Hi,

Welcome to icliniq.com

I understand how overwhelming and emotionally difficult this situation can feel. I appreciate you sharing your concerns.

For hormone receptor-positive breast cancer (ER-positive, PR-positive, HER2-negative), hormone therapy is an important part of treatment. These therapies work either by lowering estrogen levels in the body or by preventing estrogen from stimulating cancer cells, which helps slow or stop cancer growth. Many patients continue hormone therapy for at least five years as part of their treatment plan.

Commonly used hormone therapies include:

Selective estrogen receptor modulators, such as tamoxifen (Soltamox).
Selective estrogen receptor degraders, such as fulvestrant (Faslodex).
Aromatase inhibitors.
Luteinizing hormone-releasing hormone (LHRH) agonists.

Hormone therapy may be recommended before surgery to shrink a tumor, after surgery to reduce the risk of recurrence, or as a primary treatment option in advanced or metastatic breast cancer.

Hot flashes, nighttime sweating, vaginal dryness, and irregular menstrual cycles are some of the more common side effects. Therapy in premenopausal women can sometimes alter or stop menstruation. Other problems, depending on the specific drug taken, may include bone loss, mental disorders, or an increased risk of blood clots.

Certain cancer treatments can impair how your ovaries work and may cause premature ovarian failure or infertility. Fertility preservation alternatives, such as freezing eggs or embryos, should ideally be offered to women who intend to have children in the future before they start treatment. But, it is still crucial to talk to your oncologist and a fertility specialist who can tell you if there are or are not choices that are still open to you in your individual case.

I strongly encourage you to continue having these conversations with your cancer and reproductive medicine teams to help guide you toward the safest and most appropriate choices for your health and future objectives.

I hope these suggestions are helpful.
