Cancer is hereditary? How to refuse to be the "cancer second generation"
There are many cancer patients in a family. Is cancer hereditary? Cancer inheritance is not direct, that is, people with a family history of cancer do not necessarily get cancer, so there may be two reasons for disease prevention and cancer early screening. Cancer does have the possibility of heredity. These five cancers are relatively easier to inherit. 01 Colorectal Cancer 20% Mel 30% Colorectal Cancer patients have a Family History of 20% Murray 30% Colorectal Cancer patients have a family history of various types of cancer, the risk of family colorectal cancer will also increase. The most important thing to effectively prevent colorectal cancer is to change the dietary habits of high fat, high protein and low fiber. People affected by genetic factors should be examined in advance. 02 the risk of breast cancer daughters is 2-3 times higher than that of breast cancer. Women with family history should give birth as soon as possible (before the age of 30) and breastfeed as soon as possible. in order to minimize the inducing factors of breast cancer, it may be hereditary gastric cancer.
We sometimes hear that a family has cancer one after another, and there are many cancer patients in a family. Whenever I see these news, I start to wonder, is cancer hereditary? In fact, cancer is not a genetic disease in the standard sense, and cancer inheritance does not directly "inherit" cancer, but transmits cancer susceptibility genes. That is, people with a family history of cancer may not necessarily get cancer, but under the same living conditions, they may have a higher chance of getting cancer than ordinary people, so they need to do a good job of disease prevention and early cancer screening.
Why does cancer sometimes appear in the same family?
Answer: there may be two reasons
1. Cancer does have the possibility of inheritance, and some people are much more likely to develop certain cancers because they inherit familial genetic defects.
two。 Similar lifestyle and living environment, especially some unhealthy living habits, such as unhealthy eating, less exercise, smoking, etc., or being in areas with a high incidence of gastric and esophageal cancer, while being contaminated by decoration, may cause the same kind of cancer in the family.
These five cancers are relatively easy to inherit.
01 colorectal cancer
20% of patients with colorectal cancer have a family history.
20%, 30% of colorectal cancer patients have a family history of various types of cancer.
Recommendations:If a member of the immediate family suffers from familial intestinal polyposis, the family must go to the hospital for an examination. If the family likes to eat meat and high-protein foods, the risk of colorectal cancer in the family will also increase.
The most important thing to effectively prevent colorectal cancer is to change the dietary habits of high fat, high protein and low fiber, exercise actively and maintain sleep. After the age of 45, enteroscopy is performed every 5-10 years on average, or you can choose to have a fecal occult blood test once a year, and people affected by genetic factors should be examined in advance.
If you often have hematochezia, frequent stool, mucous stool and abdominal pain, you should find out the cause in time.
02 breast cancer
The risk of a daughter is 2-3 times higher.
Breast cancer has an obvious genetic tendency, especially among immediate family members. Generally speaking, if a mother has breast cancer, her daughter is two to three times more likely to get breast cancer than other women.
Recommendations:For women with family history, breast health examination should be advanced to about 30 years old, usually B-ultrasound examination before 35 years old; mammography after 35 years old, so as to detect breast cancer in the early stage. Moreover, women with genetic predisposition should consciously carry out "breast self-examination" from the age of 20, especially after menstruation, they should do "self-examination" regularly to detect physical abnormalities in time.
In addition, women with family history should give birth as soon as possible (before the age of 30) and breastfeed. Menopausal women should not misuse estrogen-containing drugs to minimize breast cancer inducing factors and reduce its incidence.
03 gastric cancer
It has a lot to do with heredity
The occurrence of gastric cancer has a lot to do with heredity, and there is an obvious family aggregation phenomenon. If at least two people in one or two generations of the family are sick, and one person is less than 50 years old, and all the patients are diffuse, it may be hereditary gastric cancer.
Recommendations:As the early lesions of hereditary diffuse gastric cancer are more hidden, gastroscopy should be performed regularly in order to detect canceration as soon as possible. The family members of such patients can eat more fresh fruits and vegetables, because a larger content of vitamin C, vitamin E can prevent the formation of carcinogens.
If you often have symptoms such as epigastric pain, bloating in the stomach, and "thinning" for unknown reasons, you should go to the hospital for diagnosis as soon as possible.
04 liver cancer
Children are the object of primary prevention.
If the parents are diagnosed with liver cancer, the children are the primary prevention targets, because the vertical transmission of hepatitis B virus is easy to cause the tendency of family aggregation of liver cancer. In particular, mothers who carry hepatitis B virus have a higher risk of liver cancer in their offspring.
Recommendations:If there are patients with liver cancer at home, if their children suffer from viral hepatitis, they should do liver B-ultrasound + AFP every six months.
Usually do not eat rotten food; do not eat sprouted food, such as germinated potatoes; do not eat fried food; abstain from alcohol; do not take drugs or health products indiscriminately.
05 nasopharyngeal carcinoma
There is an obvious familial genetic tendency.
The incidence of nasopharyngeal carcinoma has obvious ethnic susceptibility, regional aggregation and familial tendency.
Recommendations:For people with a family history of nasopharyngeal carcinoma, it is recommended to check for EB virus regularly. Diet should pay attention to avoid eating pickled food (pickled vegetables, salted fish, etc.), often eat pickled food will increase the incidence of nasopharyngeal cancer 2-7 times.
At the same time, we should pay attention to quit smoking and avoid secondhand smoke and other harmful smoke, such as kerosene lamp gas, insecticidal aerosol, formaldehyde and so on. If you find snot with blood or spit with blood after nasal aspiration, as well as unexplained cervical lymph node enlargement, middle ear effusion, etc., a detailed nasopharyngeal examination should be done in time.
For high-risk groups
7 screening methods for cancer
As most malignant tumors are asymptomatic or difficult to detect in the early stage, anti-cancer physical examination has become an effective way of intervention and management for high-risk people and those who find abnormalities.
As long as according to their own situation, regular physical examination can not only increase the precocious rate of malignant tumors, but also reduce the death caused by cancer.

Four things you are most afraid of
I'm afraid you like sports.
Physical exercise can not only help you lose weight or keep in shape, but also prevent cancer.
Studies have shown that people who do at least 30 to 60 minutes of moderate to high-intensity physical activity a day have a lower risk of cancer, especially breast and colon cancer. In addition, the incidence of several other cancers has also declined, including prostate cancer, lung cancer and endometrial cancer.
I'm afraid you have a light taste.
Gastric cancer is closely related to bad eating habits, especially too much salt does great harm to the stomach.
Remember:Nitrite-treated foods such as sausage, ham, luncheon meat and pickled meat products contain small amounts of nitrosamine carcinogens and should not be eaten frequently.
I'm afraid you'll quit smoking in time.
Tobacco and alcohol is the push to open the door to cancer. People who smoke more than 20 cigarettes a day have a higher risk of cancer than non-smokers, and women have a higher risk of cancer than men, and smoking is not only related to lung cancer. it also makes people more likely to get cancers such as stomach, colorectal, cervical cancer, breast cancer and so on.
Remember:It's never too late to quit smoking in time!
I'm afraid you'll be in a good mood.
Among the adverse emotional reactions, depression, strong frustration, hopelessness and helplessness are closely related to cancer. Some people think that "depression catalyzes the tumor". For example, women with severe depression are more likely to develop breast cancer and have a poorer prognosis after developing cancer.
