What is the incidence of IVF cancer?
The development of IVF technology has enabled many infertile couples to achieve their reproductive aspirations. Nevertheless, people have been worried about whether IVF will increase the incidence of cancer. This article will discuss the incidence of cancer in IVF and related research results from four aspects.
1. Whether the cancer risk of IVF is increased
Research in the past decades has shown that compared with normal infants, IVF has no significant increase in the risk of cancer. However, some studies have shown that the risk of IVF cancer is slightly increased, but still at a low level. For example, a British research report points out that the risk of cancer in test tube infants is 0.3% higher than that in normal infants. However, it needs to be clear that this increased risk may be related to related factors (such as mother's age, family genetics, etc.).
A recent study has supplemented this. The Medical Center in Sydney, Australia, followed 4000 IVF babies for 18 years, and the results showed that there was no significant difference in the risk of cancer between IVF babies and naturally conceived children.
Therefore, it can be preliminarily concluded that the risk of cancer in IVF is relatively low, which is equivalent to that of naturally conceived children.
2. Specific diseases of IVF cancer incidence
When studying the incidence of IVF cancer, specific analysis of different types of tumors is needed. Research shows that the risk of IVF suffering from childhood leukemia is equal to that of naturally conceived children. In some special cases, such as the older mother of IVF, the risk of unique tumors may increase.
In addition, to help IVF children better monitor cancer risk, the University of Gothenburg in Sweden has carried out a long-term study. The results of this study show that IVF has a lower risk of leukemia, and the incidence of other malignant tumors is similar to that of naturally conceived children.
To sum up, although IVF may slightly increase the risk of certain tumors, in general, the incidence of cancer in IVF is comparable to that in naturally conceived children.
3. Related factors of cancer incidence and IVF technology
Some related factors are also involved in the study of the incidence of cancer in IVF. First, age is an important factor. The increase in maternal age is associated with a slightly increased risk of cancer in IVF infants. Secondly, genetic factors may also have an impact on the incidence. If there is cancer or genetic disease in the family, the risk of IVF suffering from cancer may increase. In addition, the implantation of IVF embryos and the improvement of related technologies can also reduce the incidence of cancer.
4. How to reduce the cancer risk of IVF
Although IVF has a low risk of cancer, there are still some ways to reduce the risk. First, select a hospital with excellent research and clinical experience for IVF treatment to ensure standard operation and technical expertise. Secondly, comprehensive physical examination and genetic testing should be carried out for mothers to understand the potential genetic risks. Finally, the physical examination and screening of children's cancer should be carried out regularly in order to detect and treat possible problems at an early stage.
summary
To sum up, the incidence of cancer in IVF is relatively low, which is comparable to that of naturally conceived children. Although a few studies have shown a slight increase in the risk of IVF cancer, this risk is still lower than the overall incidence of cancer. Choosing professional hospitals, paying attention to individual differences and strengthening children's cancer screening are the key measures to reduce risks.
