If a pregnant woman has cancer, will the child in her stomach also suffer?
The traditional view is that the baby's immune system has a suppressive effect, and cancer infections will not occur
Therefore, some people think that leukemia in female infants is transmitted by the mother
So, is cancer really contagious? Some scientists have done experiments on this issue
1.
In 1951, Herita Larks died of cervical cancer in the United States
The study found that when mice were injected with HeLa cells, the mice developed cancer
In view of this, the medical scientist Chester Southam decided to conduct human experiments
In 1954, Chester Southam discovered a leukemia patient.
A few days after the injection, the patient’s arm showed swelling one after another, which was diagnosed as malignant tumor
At that time, due to the special social environment, Chester Southam also conducted further experiments on healthy human bodies
He recruited 65 prisoners and injected them with HeLa cells several times in a few months
The final results showed that human cancer cells cannot be infected by injection

Helicobacter pylori, which mainly causes non-cardia gastric cancer, cardia gastric cancer and gastric non-Hodgkin's lymphoma, about 810,000 cases;
Human papillomavirus, which mainly causes cervical cancer and some oropharyngeal cancer, anal cancer, penile cancer, etc.
There are about 360,000 cases of hepatitis B virus, which mainly causes liver cancer;
Hepatitis C virus mainly causes liver cancer and other non-Hodgkin's lymphomas, with approximately 160,000 cases
1) Helicobacter pylori
Helicobacter pylori belongs to a class of carcinogens, which are mainly transmitted through the digestive tract, and the mode of transmission is oral transmission
Human papillomavirus (HPV)
HPV is a large family, and more than 100 genotypes have been discovered so far
.
Women have an 80% chance of contracting HPV in their lifetime, but most of them will be cleared by the immune system
.
If the high-risk HPV virus persists, it will increase the risk of cervical cancer
.
HPV is mainly transmitted through sex, and injection of HPV vaccine is an effective method of prevention
.
In addition, we must pay attention to sexual hygiene, and regularly perform TCT inspections or TCT combined with HPV inspections
.
3) Hepatitis B virus
Some countries are the main countries with hepatitis B, accounting for about one-third of the world's chronic hepatitis B virus infections
.
Sexual transmission, blood transmission and mother-to-child transmission are the main modes of transmission
.
After being infected with hepatitis B virus, if antiviral treatment is not given in time, it may further lead to liver cirrhosis and liver cancer
.
Hepatitis B vaccination is the main method to prevent hepatitis B virus infection
.
In addition, avoid sharing syringes with others and ensure safe sex
.
4) Hepatitis C virus
Hepatitis C virus is similar to hepatitis B virus
.
The main modes of transmission are sexual transmission, blood transmission and mother-to-child transmission
.
Current clinical no vaccine against hepatitis C
.
Therefore, after infection with hepatitis C virus, routine antiviral treatment should be carried out in time to reduce the risk of liver cancer
.

Be wary of the two main "family cancers"
In addition to carcinogens, some bad habits can also lead to the emergence of "family cancer"
.
The more common "family cancers" are gastrointestinal cancer and lung cancer
.
Gastrointestinal cancer
Gastric cancer, esophageal cancer, colorectal cancer and other gastrointestinal cancers are closely related to life>
.
Studies have found that members of the esophageal cancer family have the same characteristics in eating habits, such as insufficient animal protein intake, frequent consumption of moldy foods, and preference for hot foods
.
In addition, if more than one person is infected with Helicobacter pylori, family members are at increased risk of stomach cancer
.
Lung cancer
Smoking is the main risk factor for lung cancer
.
In addition, second-hand smoke and third-hand smoke increase the risk of lung cancer in family members
.
Therefore, in a family with more than one person smoking, the risk of lung cancer among family members will be greatly increased
.
It is heartbreaking to find cancer in this family
.
If a "family cancer" occurs, it will be a fatal blow to any family
.
Cancer is not contagious in nature, but we still cannot relax our vigilance in preventing cancer, especially to avoid "family cancer
.
