Application and limitation of IVF in cancer treatment
The development of IVF technology has brought good news to infertile couples, but also triggered some controversy about its use. Some people believe that IVF can cure all types of cancer, but is this the case? This paper will elaborate on this issue from four aspects.

1. The role of ordinary IVF in cancer treatment
Ordinary IVF refers to the technology of implanting the fertilized egg into the female uterus after in vitro fertilization of the male sperm and the female egg. This technology is not directly related to cancer treatment and cannot directly affect the growth and condition of cancer cells. Therefore, ordinary IVF does not have a direct curative effect in the treatment of cancer.
2. Application of test tube babies to preserve stem cells and organs such as baby bone marrow
After the birth of test tube babies, stem cells in their umbilical cord blood, bone marrow and other tissues can be collected and stored. These stem cells have strong differentiation ability and can be used to treat certain types of cancer, such as leukemia and other hematological tumors.
In addition, IVF can also be used as an organ donor. When a test tube baby is clinically dead, its organs can be transplanted into the patient for treatment of cancer and other diseases. However, this kind of application is restricted by many morality and laws and can only be implemented under specific conditions.
3. Advantages of Genetically screened IVF in cancer treatment
In IVF technology, some embryos carrying genetic diseases can be excluded through gene screening, and healthy embryos can be selected for implantation. This screening can help avoid some genetic diseases related to cancer, thus reducing the risk of cancer.
However, cancer has complex characteristics such as multiple genes and multiple environments, which is different from genetic diseases with a single gene. Therefore, even if healthy embryos are selected through screening, the possibility of cancer cannot be completely eliminated.
4. Progress and challenges of IVF in cancer treatment
At present, a new treatment method is called test tube baby therapy, which uses the immune cells of leukemia patients to fight against cancer cells. This method has made remarkable progress in the treatment of some types of leukemia.
However, the IVF therapy is still in the primary stage of research and has not been widely used in clinical practice. In addition, there are many types of cancer and different types of cancer cells have different sensitivity to anticancer drugs. Whether IVF can cure all types of cancer remains controversial.
conclusion
IVF has certain application prospects in the treatment of cancer, such as preservation of stem cells and organs and gene screening. However, ordinary IVF cannot cure cancer directly. Test tube baby therapy may have some effect on some specific types of cancer, but whether it can cure all types of cancer still needs further research and exploration.
