Do Fertility Treatments Cause Cancer Heres the Truth, According to Experts

Do Fertility Treatments Cause Cancer Heres the Truth, According to Experts There are few decisions more life-altering than a person or couple deciding it is time to start expanding their family. When a couple starts to try to conceive and are not successful, it can be incredibly disruptive and disappointing. Infertility is very common, as it affects one in eight people. Yet, the causes for and treatment of infertility are mucksmuschenstill confusing for many. Perhaps thats because we tend to not discuss them, and stigma creates bewilderment.In Vitro Fertilization (IVF) is a very common treatment for infertility. The CDC reports that approximately four million babies born in the US each year were conceived by IVF. Ubiquitous as it may be, IVF is perplexing for some from the process of IVF to what the side effects are.Unfortunately, one myth of IVF treatment persists that IVF can cause cancer. For important health questions, its best to consult an expert. I talked to Matthew Lederman, MD, a board-certified Reproductive Endocrinologist and Infertility Specialist at RMA of NY, a clinic in Progynys Provider Network. Dr. Lederman has a specialty in fertility preservation egg or embryo freezing for those recently diagnosed with cancer. He serves on the Medical Advisory board of FORCE Facing our Risk of Cancer Empowered, as well as the Scientific Advisory mainboard for TEAL Tell Every Amazing Lady About Ovarian Cancer. Dr. Lederman is an expert on all aspects of fertility and more than qualified to address the question of IVF and Cancer.Before we address the myth that IVF causes cancer, it makes sense to understand what IVF is on a high level. In Vitro Fertilization literally means in the glass fertilization. What that refers to is fertilization of an egg by a sperm happening in a dish as opposed to in vivo fertilization, or fertilization happening in the body. Dr. Lederman explains that an IVF cycle starts with a woman administering daily shots of hormones for 8-12 da ys. The hormones work to increase the number of growing follicles, which contain eggs in a given month. As you give yourself the shots, you are monitored by your doctor to make sure your ovaries are responding to the stimulation medication appropriately. Once the follicles have grown to the appropriate size, the patient then undergoes an egg retrieval, a minimally invasive procedure taking less than 15 minutes to complete, to remove eggs from the ovaries. Under sedation, a fertility specialist extracts eggs via ultrasound guidance. If you are freezing eggs, the process stops here. If you are creating embryos, Dr. Lederman goes on to explain that, the retrieved eggs are fertilized with sperm, and then allowed to grow in the embryology lab.The science of IVF is relatively new, as sciences go. The first IVF baby, Louise Brown, is 40 years old. Dr. Lederman says that this young science is rapidly evolving in that, the current focus is no longer simply on assisting individuals to achieve pregnancy, but advancements in IVF and genomics have shifted the goal to achieve a single healthy baby, by which he indicates the advances have made possible elective single embryo transfers, which decrease multiple pregnancies (which are inherently more dangerous).Perhaps the myth of IVF causing cancer exists because it is understood that some female cancers (breast, ovarian and uterine) are affected by the hormones produced by our brains and ovaries.Estrogen and progesterone play important roles in human reproduction. Some cancers, called estrogen and progesterone receptor cancers, depend on estrogen and progesterone to grow. We also know that during an IVF cycle your hormone levels increase. The same hormones that can feed unterstellung types of cancer stimulate your ovaries to produce multiple follicles. However, Dr. Lederman reassured me that IVF does not cause cancer, and he has evidence-based research to back up his assertion. He says that, well-designed studies to date do n ot link IVF to breast cancer, invasive ovarian cancer, or uterine cancer.I asked him whether the elevated hormone levels during an IVF cycle could cause harm, and he responded by saying that the estrogen level is elevated only temporarily. One of the more recent innovations of IVF includes a special shot at the end of the cycle, called a trigger shot. This shot causes the final maturation of the eggs in the ovaries and uses an additional medication to quickly return the hormone levels to baseline.Another reason for the misinformation about the relationship between IVF and cancer are previous studies, which incorrectly reported an association.Dr. Lederman says that research, was based on old, poorly designed studies that were limited by small sample sizes, imprecise drug exposure information and treatment indication, and short term follow up. He says that this a question that many of his patients ask him. He reassures individuals and couples that studies show no greater risk for canc er in those who have undergone IVF treatment.For those with a strong history of cancer in their families, Dr. Lederman recommends a conversation with a genetic counselor and perhaps expanded screening. Generally speaking, we can all make responsible choices to decrease our risk of a cancer diagnosis. Dr. Lederman recommends that women maintain a healthy lifestyle, which includes smart food choices and regular exercise. Avoiding smoking is another responsible choice. He also advocates for Hepatitis B and HPV immunizations, as well as safer sex practices, such as prophylactics, to protect against HPV, HIV and Hepatitis, all of which can increase risk of certain cancers. Dr. Lederman says that maintaining annual physician visits, breast exams, skin exams, pap smears, STD tests, mammograms, and colonoscopies will also help keep your health in check.An infertility journey can be a rollercoaster of really big highs and devastating lows. Knowing you are under the care of a good doctor, suc h as Dr. Lederman, is paramount. Asking questions, even if they seem silly, will alleviate as much stress as possible. Understanding each step of the process is important to set your expectations and make the best plans. Knowing the risks is vital I hope it makes it a bit easier to know that cancer isnt a risk of IVF. Going through IVF can be stressful enough, but understanding that it wont have lasting effects to your health should help.--Lissa Kline, LCSW is currently the Director of Member Services at Progyny, overseeing the Patient Care Advocates.
