The Hidden Risks of Egg Freezing: What Science Reveals

Egg freezing is often seen as a modern miracle — giving women more control over their fertility, enabling them to delay motherhood, and offering peace of mind in uncertain times. But behind the growing popularity lies an important question that many hesitate to ask: Are there hidden health risks linked to egg freezing — especially when it comes to cancer?

While the procedure is largely safe and widely practiced, it’s essential to explore the lesser-known aspects — including the potential link between egg freezing and cancer risk, and how current science views the long-term effects of hormonal stimulation used during the process.

Let’s discuss this important topic, separating fact from fear with clarity and compassion.

What Is Egg Freezing and Why Is It So Popular?

Egg freezing, medically called oocyte cryopreservation, is a fertility preservation technique where a woman’s eggs are retrieved, frozen, and stored for future use. It’s most commonly chosen by:

• Women who want to delay pregnancy due to personal or professional reasons
• Those undergoing treatments like chemotherapy that may affect fertility
• Individuals with medical conditions like endometriosis or early menopause

With advances in vitrification (rapid freezing), the egg freezing success rate has improved significantly. In top fertility clinics, frozen eggs can lead to pregnancy rates that are nearly equal to those of fresh eggs.

But as the number of women opting for this procedure increases, so does the need to understand the full picture — including the potential impact of hormones on long-term health.

The Process: How Egg Freezing Works

Before retrieving eggs, the ovaries are stimulated using injectable hormones like FSH (follicle-stimulating hormone) to produce multiple mature eggs in one cycle. This is followed by an ultrasound-guided retrieval procedure and immediate freezing of the eggs in the lab.

It’s during the stimulation phase that concerns around egg freezing and cancer risk arise. The worry is whether repeated or high-dose hormone exposure can increase a woman’s likelihood of developing hormone-sensitive cancers, such as breast, ovarian, or uterine cancer.

This brings us to a very important question.

Is There a Link Between Egg Freezing and Cancer Risk?

Here’s the short answer: Current research does not show a clear, direct link between egg freezing and increased cancer risk.

However, the topic is complex and still under study. Let’s look at what science tells us so far:

1. Breast Cancer Risk
   Studies involving women who underwent fertility treatments (including egg freezing and IVF) have shown no significant increase in breast cancer risk in the general population. However, for women with a family history of breast cancer or known genetic mutations like BRCA1/2, the relationship is more nuanced.
2. Ovarian Cancer Risk
   The majority of studies have found no conclusive evidence linking fertility hormone stimulation with ovarian cancer. However, a slight increase in borderline ovarian tumors has been observed in a small subset of women who underwent multiple IVF cycles. Whether this applies to women who undergo egg freezing once or twice remains unclear.
3. Endometrial (Uterine) Cancer Risk
   There is no strong evidence suggesting that hormone therapy used in egg freezing increases the risk of endometrial cancer.

So, while the concern around egg freezing and cancer risk is valid and deserves attention, current evidence does not indicate a significant threat. The hormones used are similar to those naturally produced during the menstrual cycle — just in higher, controlled doses.

A reputed IVF Centre in Delhi will always perform a thorough health assessment before starting treatment and advise against the procedure if there is any heightened individual cancer risk.

Who Should Be More Cautious?

While egg freezing is safe for most women, extra cautifon is necessary for:

• Women with a personal or family history of hormone-sensitive cancers
• Those with BRCA1/BRCA2 mutations
• Women with unexplained breast lumps or abnormal mammograms
• Patients with prior exposure to high estrogen levels

In such cases, it’s critical to consult an experienced IVF Centre in Delhi, where the fertility specialist will tailor the stimulation protocol, limit exposure, and coordinate with an oncologist if needed.

Can Egg Freezing Be Done After a Cancer Diagnosis?

Yes. In fact, egg freezing is often recommended before starting chemotherapy or radiation, as these treatments can damage ovarian function.

However, timing is key. The stimulation cycle must begin quickly — usually within 10 to 14 days of diagnosis — and close coordination between the oncologist and fertility team is essential.

Women undergoing fertility preservation post-cancer treatment will not be exposed to added cancer risk through egg freezing, as the egg retrieval and freezing process can be done without significantly affecting their overall treatment plan.

A well-equipped IVF Centre in Delhi can facilitate fast-tracked protocols for cancer patients, ensuring safety without compromising treatment timelines.

Egg Freezing Success Rate: Does It Vary with Age or Health?

Yes, it does. While concerns about egg freezing and cancer risk are still being studied, the chances of a successful pregnancy from frozen eggs are well established.

Here’s what statistics show:

• Women under 35 who freeze 15–20 eggs have a 60–70% chance of live birth later.
• Women aged 35–38 have a 40–50% success rate.
• After age 40, the egg freezing success rate drops to 10–20%, due to declining egg quality.

This is why fertility experts recommend freezing eggs at a younger age, ideally before 35.

Top-performing IVF Centre in Delhi facilities use advanced egg-freezing technology and offer fertility counselling to help women make informed decisions.

Are There Other Risks of Egg Freezing?

While concerns around egg freezing and cancer risk often dominate the conversation, it’s important to understand that like any medical procedure, egg freezing carries its own set of potential — though generally rare — side effects. Being informed about these risks allows women to make empowered decisions and seek timely support when needed.

Let’s take a closer look at the possible risks beyond cancer, many of which are manageable and significantly reduced when the process is carried out at a trusted IVF Centre in Delhi under expert supervision.

1. Ovarian Hyperstimulation Syndrome (OHSS)

One of the more talked-about complications, OHSS occurs when the ovaries over-respond to fertility medications. This results in swollen, painful ovaries and abdominal bloating. In severe cases (which are rare), it may lead to fluid accumulation in the abdomen and chest.

However, with advancements in medication protocols and close monitoring, the risk of OHSS is now much lower. A well-established IVF Centre in Delhi will adjust hormone dosages based on individual response and step in early if any symptoms arise.

2. Bleeding or Infection

During the egg retrieval process, a thin needle is inserted through the vaginal wall to collect eggs from the ovaries. While this is a short and safe procedure, there is a very small risk of internal bleeding or infection.

The chances are rare — especially when performed in sterile settings — and any complications that do occur are typically mild and treatable. Fertility specialists with years of experience minimize such risks by using ultrasound-guided precision and strict infection control measures.

3. Emotional and Psychological Stress

What’s often not discussed enough is the emotional toll of fertility preservation. For some women, especially those undergoing egg freezing due to cancer treatment or chronic illness, the process can be emotionally taxing. Hormone injections may cause mood swings, and the uncertainty of future outcomes can trigger anxiety.

Moreover, the pressure surrounding decisions related to future parenthood can weigh heavily on the mind. That’s why emotional support — through counselling or fertility coaching — is just as essential as medical guidance.

Many reputable IVF Centre in Delhi facilities now offer integrated counselling services to help women navigate the psychological aspects of egg freezing and fertility treatment with confidence.

Despite these concerns, it’s worth noting that most of the risks associated with egg freezing are rare and highly manageable. Modern fertility centres monitor every stage of the process with precision — from hormone levels to ovarian response, and post-procedure recovery.

When carried out by an experienced team at a top IVF Centre in Delhi, the safety profile of egg freezing remains strong, and the benefits can far outweigh the temporary discomforts or mild side effects.

Understanding the full scope — from the widely discussed egg freezing and cancer risk to the lesser-known physical and emotional challenges — allows women to move forward with clarity, realistic expectations, and a sense of control over their reproductive journey.

How to Make the Right Decision?

When it comes to fertility, every woman’s situation is different. The decision to freeze eggs should be based on a combination of medical facts, personal goals, and emotional readiness.

If you are considering egg freezing and are worried about potential cancer risk, it’s essential to:

• Get a full health evaluation
• Discuss your family and personal medical history
• Choose an experienced IVF Centre in Delhi that follows the highest standards of safety and ethics
