Therefore, when pregnant women are healthy, more and more people will choose to give birth naturally.
Recently, however, an academic paper in Japan has attracted the attention of medical circles at home and abroad.
In this paper, it is mentioned that two rare cases of lung cancer in children were found, but they were not "infected" through genetic inheritance, but "infected" during the mother's natural delivery!
So how are children "infected"? Will natural childbirth increase the chance of cancer "infection"?
After the rumors have been verified by many parties, this will be explained to you ~
Lung cancer is known as the "number one killer" in cancer, ranking first among all kinds of cancer mortality all the year round.
Generally speaking, air pollution, smoking and heredity are the main causes of common lung cancer.
Mother-to-child transmission of cancer is extremely rare, with a probability of about one in 500,000.
Prior to this, there were 18 cases of mother-to-child transmission of cancer in the world, all of which were transmitted through placenta.
Recently, however, the National Cancer Center of Japan found that the two babies we mentioned did not get lung cancer through the above reasons.
As for how they "infected" with lung cancer, we need to start with "natural delivery".
Studies have shown that it is extremely rare for a mother with cancer to transmit cancer to her offspring, with an incidence rate of about one in five hundred thousand.
The phenomenon of cancer transmission through placenta is rare, and the two cases of cancer transmission through birth canal in this paper are even rarer.
How can researchers determine that fetal cancer is transmitted through the birth canal?
Generally speaking, if cancer is transmitted through the placenta, the cancer focus may spread to all parts of the child's brain, bones, liver and soft tissue.
However, the cancer focus of these two cases was found to be located in the respiratory tract after examination by doctors.
Therefore, the researchers concluded that the two babies developed lung cancer through the birth canal.
That is to say, their mother's cervical cancer cells exist in amniotic fluid, secretions or blood. During natural delivery, babies inhale these tumor cells from their mothers into their lungs.
In the end, the baby who gave birth naturally unfortunately suffered from lung cancer.
In this case, the mother of a 2-year-old child did not find cervical cancer during pregnancy, and it was not discovered until 3 months after the child was born.
And both mothers gave birth to their babies through natural childbirth.
Therefore, for mothers with cancer, the researchers suggest choosing cesarean section, which can reduce the risk of transmitting cancer to their babies (please follow the doctor's advice for details).
It is understood that the mothers of these two children may have cervical cancer during childbirth, but they were not diagnosed until after the children were born.
As can be seen from the above picture, cervical cancer ranks eighth among all cancers.
The main and most common cause of cervical cancer is the persistent infection of human papillomavirus (HPV).
According to statistics, more than 90% of cervical cancer is accompanied by high-risk human papillomavirus infection, and the most effective way to prevent this kind of virus infection is to vaccinate HPV vaccine in addition to regular gynecological examination.
In fact, the incidence of cervical cancer can be greatly reduced if women are vaccinated with HPV at the right age.
At present, bivalent, tetravalent and nonavalent human papillomavirus vaccines can target different types of human papillomavirus, and they all have significant preventive functions, providing a solid defense line for women.
Finally, rumors remind expectant mothers to pay attention to their own health and have regular physical examinations, for the sake of a healthy baby and a healthy you.
