Her mother, her grandmother, and many direct female relatives in the family all have this disease, which shows that the genes of the women in this family are defective.

Because Angelina Jolie carries a defective gene, doctors told her that her chance of developing breast cancer is about 87%, and her chance of developing ovarian cancer is 50%.

So she decided to take a preemptive strike and minimize the possibility of the disease through surgery.

After the operation, the possibility of Julie suffering from breast cancer dropped from 87% to 5%. Although it is not 100%, at least the red alert has been lifted.

There was just no way to take the sexy route, so this sexy girl started to take the white left political route, which made her less lovable.

I give this example to illustrate that cancer, like other family history diseases, may be hereditary, but the inherited parts or organs are the same or close.

But the situation of Shen Lifen and her child is completely different, which makes people think a lot.

While everyone's attention is focused on "heredity," Chen Qi has a different opinion.

"No, no, no, I don't think Shen Lifen's cancer will be passed on to his son."

As soon as he said this, a middle-aged doctor in the office couldn't help it:

"Dean Chen, you clearly said before that the child's cancer may come from the mother, and now it has been initially confirmed that your guess is correct. Why are you denying this statement now?"

Chen Qi waved his hand: "No, no, no, it's not a denial, but if the cancer cells come from the mother, it's not necessarily hereditary, it could also be infection?"

Director Xu Jinxing burst into laughter:

"Good guy, do you really insist that cancer is contagious? There is no relevant theory or evidence for this so far. If we just write it in a paper and publish it, we won't be laughed at by our colleagues around the world. You’ve lost your big teeth.”

Hehehe~~~

Everyone in the office chuckled.

Doctors all know that the placenta has a barrier function, and it is difficult for viruses and bacteria to pass through, let alone cancer cells.

Only Dean Guo had his eyes closed and didn't know what he was thinking, and he didn't question Chen Qi's statement.

Chen Qi also laughed a few times, but he still had to persevere:

"Is it contagious? Now that I am making this statement, of course it needs to be confirmed. In this way, I personally went to Japan. Last time I checked the basic chromosomes. This time it is a big project and I need to check Shen Li. Fen and her child's cancer cells undergo a comprehensive testing and sequencing."

Seeing that Chen Qi was speaking so seriously, Director Xu started to think about it.

Genetic testing was still a completely unfamiliar medical concept to Chinese doctors in 1986.

Even abroad, this is actually a newly emerging biological technology. How it will be applied clinically and how significant it will be to clinical practice are still unknown.

Human cells have a total of about 3 billion base pairs of DNA. Everyone's DNA is not exactly the same. The number of different base pairs between people is as many as millions. Therefore, molecular biology methods are used to detect diseases. ,This is a big project.

To put it simply, paternity testing, a familiar genetic test, was not officially promoted until the 1990s.

Director Xu roughly understood what Chen Qi meant, but he still had to confirm again.

"Chen Qi, what is the purpose and significance of doing genetic testing on both mother and child?"

"Well, whether cancer is transmitted from mother to child, only genetic testing can reveal the answer. I want to sequence the two tumor genes. If the tumor genes of the mother and child are the same, then we have solved the case. No. If we figure out the origin of neonatal lung cancer, our topic will be meaningless. What do you think?"
