Is a healthy conception possible with a cancer risk history?

Question

Hello doctor,

My wife and I are both 31 years old, and we recently discovered that she carries a BRCA1 (breast cancer gene 1) mutation while I carry a CHEK2 (checkpoint kinase 2) mutation after genetic counseling due to strong family histories of cancer on both sides. We are trying to navigate family planning with these genetic risks, and it feels overwhelming.

We want children, but we are concerned about passing these mutations to our children and the timing of preventive measures for my wife. She has been advised to consider prophylactic mastectomy and oophorectomy, but we are not sure how this affects our fertility timeline. We are considering preimplantation genetic diagnosis (PGD) to reduce the risk of passing these mutations to our children, but we are concerned about the stress and cost of IVF (in vitro fertilization), especially since we do not have any fertility issues.

My wife is also struggling with anxiety about her cancer risk, which is affecting our intimate relationship and her menstrual cycle. Her periods have become irregular, and she is experiencing symptoms that make her worry. We are also concerned about how her future surgeries might affect our sexual relationship and her sense of femininity.

How do we balance the timing of preventive surgeries with our desire to have biological children?
Is preimplantation genetic diagnosis worth the physical and emotional costs in our situation?
How might prophylactic surgeries affect our sexual relationship and her hormonal health?
What are the psychological impacts of genetic cancer risk on fertility and relationships?
How do we support each other through these difficult decisions while trying to conceive?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

This is a deeply challenging situation, and, understandably, you and your wife feel overwhelmed as you try to balance cancer prevention with family planning. For women with BRCA1 (breast cancer gene 1) mutations, risk-reducing surgeries such as prophylactic mastectomy and oophorectomy are strongly recommended because they significantly lower the chances of breast and ovarian cancer. But the timing is highly individualized and usually guided by both cancer risk and reproductive goals. Oophorectomy is often delayed until after childbearing, since it causes infertility and early menopause, while mastectomy can sometimes be timed flexibly around pregnancy plans.

Preimplantation genetic diagnosis (PGD) through IVF (in-vitro fertilization) can reduce the chance of passing on BRCA1 or CHEK2 (checkpoint kinase 2) mutations. Still, it is a physically and emotionally demanding process and not the right path for every couple, especially when there are no fertility problems. Many couples weigh the benefit of lowering genetic risk against the strain and cost of IVF.

Prophylactic surgeries can affect body image, sexual intimacy, and hormonal health, but reconstructive options and tailored hormone replacement therapy after oophorectomy can help mitigate these effects, and open communication between partners is key in preserving closeness. The psychological burden of living with hereditary cancer risk often creates anxiety, guilt, and strain on intimacy, which is why counseling, both genetic and psychological, can be as important as the medical decisions themselves.

Supporting each other means acknowledging these fears openly, making decisions as a team, and seeking guidance from a multidisciplinary team that includes oncology, reproductive medicine, and mental health professionals. This way, you can move forward with a plan that protects your wife’s health while allowing you both to build the family you want.

I hope this answers your query.
