Does IVF contribute to oncology?

In connection with the widespread use of IVF as a method to combat infertility, there is a new and new information about the long-term effects of human intervention in the affairs of nature, in particular, in reproduction. So, you can often hear that women who have undergone IVF risk being among the patients of the oncologic dispensary. Is this true and what are the risks in fact, we will tell in this material.

IVF worldwide has been done for over 40 years. From a philistine point of view, it is long. From the point of view of science, it is too little to be able to speak with confidence about all possible long-term consequences.

The Englishmen spoke first about the dangers of in vitro fertilization and the relationship of this procedure with oncology, they conducted a study at the University of London, which showed that women who had IVF experience had a 37% higher chance of developing oncology. At the same time, cancer after IVF was detected mainly in young women (up to 35 years).

After a more thorough study, the British apologized to the world community and acknowledged that most often women had cancer at the initial stage even at the time of IVF. Actually, most likely, it was he who caused their infertility, which pushed the ladies to artificial insemination.

A few years later, Israeli scientists reported on their work: they watched a group of 10,000 women after IVF. The findings were disappointing - the likelihood of cancer after this procedure rises to 40%. In 60% of cases, lung cancer was detected, in 85% - breast cancer. This was followed by cervical and ovarian cancer, thyroid and stomach.

Israeli experts explained that the increased risks are created by aggressive hormone therapy, which a woman undergoes at the preparatory stage, when she stimulates the growth of follicles in her ovaries, and at the stage following embryo transfer. And considering that the probability of getting pregnant from the first protocol is not so high, many women have to endure hormonal upheavals during 6, 7, 8 or more attempts to get pregnant.

A little later, Israeli scientists corrected themselves and refuted the connection with IVF oncology of any other organs, except for the mammary gland, ovaries, uterus, and its cervix. This step of their somewhat embarrassed experts, but did not touch the most ardent opponents of IVF. Now some people, even demanding the rejection of artificial insemination for religious reasons, refer to this study of Israel.

Americans went further than other researchers. They took a large control group - about 70 thousand women, who for the period from 1994 to 2011 did IVF. At the same time, the second group was created - it consisted of 19,000 women, those who refused IVF for some reason or reason. As a result, it turned out that the incidence of cancer in both groups was about one and a half thousand cases.

In 2007, Danish experts decided to conduct an experiment with their patients and also did not find the relationship between IVF and cancer diseases.The study analyzed information on 55,000 women who were diagnosed with breast cancer. Among them, who made IVF was, according to statistics, about 10%. All the other patients of the clinic, who were treated there at different times in the past 30 years, were either childless or pregnant and gave birth in a completely natural way and never thought about IVF.

Scientists and doctors are still engaged in the search for truth and it is too early to say which of the researchers is right. To date, the claim that IVF causes such a dangerous complication, like cancer, provokes the growth of cancerous tissues and metastases, has not been proven. Many oncologists are not inclined to discern any relationship. But they also do not seek to deny it, because the causes of cancer are a secret for scientists.

If you go to the facts, you can remember Joan Friske. She was diagnosed with cancer some time after giving birth. Son Plato was born after a successful IVF protocol. The wife of Konstantin Khabensky, who also IVF had done shortly before, died of cancer.

Experts in the field of oncology claim that in both cases women already had cancer and simply no one knew about it. Pregnancy has created an additional burden on the body, which provoked the active stage and the progression of the disease.

If you have to IVF, do not panic and fear the most sad outcome. Direct evidence that IVF provokes oncology does not exist. However, it will be useful before the next protocol to pass not only the analyzes that the reproductive specialist wrote out, but also to make an analysis for tumor markers. This will help to notice the pathology and undergo treatment as early as possible

According to the observations of oncologists, cancer is quite often found in women who, when not diagnosed, form and stage of the disease became pregnant by natural means. The load on the body and in this case is great, which also leads to the development of severe illness. Some cancers are hormone dependent. This applies to thyroid cancer or breast cancer, for example.

With all the variety of thematic forums for women on the Internet, they could not find at least one plausible history of cancer detection after IVF. All the stories described by users are written in the third person, they tell about "one friend", about "neighbor's friend", about "former employee's sister". Very often, women themselves confuse with this the accompanying pregnancy pathology, premature birth of children, prematurity of children and problems associated with this, with the consequences of IVF.

In fact, premature labor can occur after natural conception, IVF has nothing to do with it.

The question of possible oncology, of course, is one of the most exciting. But lately there are more and more women who are able to weigh the arguments and ponder on scientific information, and it is they who most often convince their panicked “colleagues” on the Internet to stop sowing panic and spread unverified rumors.
