As they were talking, a young man came in, followed by two old people, who looked like his parents.

The young man's face was dark and gloomy, and the two old men also had a sad face.

"Sit down!" Song tingshen said that since he came to the cancer hospital, there must be something wrong.

The young man took out his medical record. Song tingshen saw that the man was Chen Yuan, only 26 years old.

The medical record should have been from Anhui Province when I saw a doctor in my hometown. It was diagnosed as advanced liver cancer with portal vein metastasis.

"Doctor, my son..." Chen Yuan's mother shed tears as soon as she opened her mouth. She was very distressed when she thought that her son had cancer at a young age and was still in the late stage.

"The doctors in the hospital in my hometown said it was liver cancer, which can be treated only in Beijing. They also said that only the doctors in the cancer hospital can be optimistic, so we came." Chen Yuan's mother wiped her tears and said, "doctor, can my son still be cured?"

Song tingshen looked through the medical records and didn't speak. The previous diagnosis seemed to be liver cancer and portal vein metastasis caused by liver cirrhosis. Fortunately, there was no lung metastasis, otherwise it would be hopeless.

"Let's have a detailed examination. We can't use these in your hometown. Our hospital has more advanced equipment to make a clearer diagnosis." Song tingshen said.

"Do whatever you say you want." Chen Yuan's father nodded.

"Doctor, I read the newspaper that you can do liver transplantation here, can't you? Does that mean I still have hope? " Asked Chen Yuan.

Song tingshen nodded. "Theoretically, it's like this. We have to do a detailed examination to see if there is a need for liver transplantation. In addition, it's difficult to find the liver source."

"I heard that relatives can donate liver to their children? I will. I will cut my liver in half for my son. " Chen Yuan's mother said in a hurry.

"We will depend on the situation. Let's go to the hospital for examination first." Song tingshen nodded.

After the bill was issued, Chen Yuan's father went to pay the fee, and then began various inspections.

The results of the examination are similar to those of the previous hospital. Liver cirrhosis, the tumor can not be removed locally, and it doesn't have much effect.

The cancer cells have not yet metastasized to the lungs and other organs, but the portal vein has metastasized.

The portal vein system is in the liver. It is a venous vascular system that collects the reflux of abdominal blood. The portal vein finally flows into the vena cava and then flows back to the right heart.

Therefore, liver transplantation is still useful. If the lung has metastasized, it is to transplant a new liver, and the cancer cells will turn back and end the liver again, so it will be done in vain.

If you transplant it, remove it together with the portal vein, cut off all the parts with cancer cells, and move it into a healthy liver, you have a great chance of survival.

Chen Yuan's parents said they were willing to donate liver for their son, so song tingshen ordered them to draw blood, first to see who had the same blood type, and then to check whether their bodies could bear the risk of liver cutting and whether they met the requirements of liver donation.

Just like Lin Jing'an before, his mother was a fatty liver. She also ran away for several months before she could donate her liver to her son.

The two men had a blood test and took the blood test report. Anzehan looked at it first, "it's impossible!" He exclaimed.

"What's the matter?" Guo Xiang asked hurriedly.

Song tingshen glanced at an Zehan. He stuck out his tongue and handed song tingshen the blood test report.

Guo Xiang looked behind him and frowned. Both Chen Yuan's parents' blood types were type A, but Chen Yuan was type ab. this is impossible. Two people with type a blood can't have children with type AB blood at all.

Most likely, Chen Yuan is not his parents' biological child.

Guo Xiang looked up at the two old men. They both looked worried and worried. They could see that they were very concerned about their son. Did they not know that their son was not their own, or did they care just because he was their own son?

Song tingshen put the blood test report on the table. He was a little helpless. "You two can't donate liver to your child. Your blood types don't match."

"No? Why not? The child's blood type is either the same as me or his father? " Chen Yuan's mother doesn't understand.

"That's not necessarily. The child's blood type may also be different from his father..." Guo Xiang said, but it's not the same problem. These are two children with type a blood roots who can't produce type AB blood. It seems that they don't know at all.

"Mother Chen Yuan..." Song Ting thought deeply about how to talk to the old man, "isn't Chen Yuan your own child? Is it adopted? "

"Yes, how come it's not my own? It was born to me. I was born in October. " Chen Yuan's mother was shocked.

Chen Yuan and his father were shocked, "what's going on?"

"Look..." song tingshen pointed to the blood test report. "Your parents are type a blood. You can only be type A or type O. the probability of type O is very small. It is most likely type A, but you are type AB, which is impossible in medicine."

"So you shouldn't be your parents' own son." Song tingshen said.

"This..." the three people were shocked. "Won't there be an exception?"

"No!" Song tingshen shook his head, "there is no exception. With the development of medical technology for so many years, the blood type has been very mature and clear. There is no exception..."

"Dad, mom..." Chen Yuan looked at his parents in pain. Did they hide it from him for so many years?

"No, no, no!" Chen Yuan's mother shook her head desperately, and tears gushed out like a spring. "I didn't give birth to you until I was pregnant in October. Why aren't you my own? You're my shit and urine. Why aren't you my own?" Chen Yuan's mother cried bitterly.

Chen Yuan's father also red eyes, "yes, I was at home when your mother conceived you. I saw you born with my own eyes. How could it be?"

"Could it be that the child was held by mistake in the hospital?" Anzehan said.

"It's really possible." Guo Xiang nodded, so even his parents didn't know.

"What about that?" Chen Yuan's mother panicked.

"What about our children?" Chen Yuan's father's face turned white.

"Then you can only ask yourself, which hospital did you give birth to your children in those years? Was it in the hospital? Was there another child born and the nurse held it wrong? " Guo Xiang asked.

"Yes, they were born in the hospital..." Chen Yuan's mother recalled that they were from the county, not from the countryside, so they were born in the hospital. "There were several children in the delivery room that year. Was it really wrong?"

"What can I do? After all these years, can you still find it? " Chen Yuan's father frowned with worry.

"If you can't find it, you have to find it. Let alone our own son, we have to help Yuanyuan find his own parents, but they can save Yuanyuan." Chen Yuan's mother cried bitterly, "Yuanyuan is only 26 years old. He still has a long way to go. He can't find his parents. What should he do?"

Chen Yuan's tears also came down. He was very moved. He was so afraid that he was not the biological son of his parents. They would ignore themselves. Fortunately, they loved themselves.

"Yuanyuan, don't worry, we will find your biological parents and save you!" Chen Yuan's father also said firmly.

Whether born or not, how can a son who has loved him for decades give up? After so many years of feelings, they love their child very much. How can they ignore him?

"Then go find it quickly. Time waits for no one!" Song tingshen said.

The life span of advanced liver cancer is generally only a few months. I don't know how long to find someone. I'm really afraid I can't find it.

Guo Xiang is also worried that this period is not as developed as the communication of later generations, and the hospital has no computer to check. For decades, the information of the hospital has not been retained, which is a little difficult.
