Cancer is a common disease in life, especially in recent years, when the incidence of cancer around people is getting higher and higher, so that most people feel extremely panicked.
Cancer is a malignant lesion caused by abnormal proliferation of human epithelial cells and gene mutations. In severe cases, it can cause a series of abnormal changes, causing organs throughout the body to be affected.
Cancer appears particularly quietly, and many people confuse their symptoms with other diseases at first. Missed the best times.
Cancers sometimes occur within the same family and may be caused by common genetics or environmental factors among family members.
Some inherited genetic mutations are thought to increase the risk of developing cancer. These genetic mutations can be passed on to future generations, making these people more susceptible to cancer. For example, bruka syndrome and familial breast cancer Ovarian cancer syndrome are some of the heritable cancer disorders. In general, cancer in families is not necessarily hereditary. Because the occurrence of cancer is very complex, there are not only genetic factors, but also environmental factors and other factors.
1.Liver cancer
There is a genetic predisposition to liver cancer, which means that if the grandparents have had liver cancer, the chance of the offspring developing liver cancer will be much higher.
Of course, if your parents are liver cancer patients, your children are at risk of liver cancer patients, and the probability of the disease is quite high.
Especially if the parents are carriers of the hepatitis B virus, the incidence of liver cancer in the next generation is even twice as high as that of normal people. When you find that you are unwell, you should seek medical examination in time, and you can accurately detect whether you have liver cancer through abdominal color ultrasound and alpha-fetoprotein detection.
2.Bowel cancer
Nowadays, the incidence of colorectal cancer is also relatively high, which is closely related to diet. Moreover, the hereditary rate of colorectal cancer is relatively high, and 20% to 30% of colorectal cancer patients have a certain familial hereditary, so it is also necessary to have regular colonoscopy.
After the age of 45, it should be done once every 5 to 10 years on average, so that you can effectively understand your health status and avoid colorectal cancer.
3.Lung cancer
In fact, it is generally believed that lung cancer is not hereditary, but lung cancer has a very obvious tendency to grow in families. This is because all members of a family have lived in the same environment for a long time and have similar diets and Xi.
Especially if there are smokers in the family, other family members will passively inhale second-hand smoke for a long time, and the risk of lung cancer will increase.
In addition, germline mutations and genetics are related to the genetic relationship in lung cancer genes, and the presence of germline mutations such as EGFR, ALK, RET, and BRCA in the body, as well as the genes responsible for activating ROS1 and RET cell enzymes may also lead to the appearance of lung cancer.
4.Breast cancer
In general, breast cancer has a strong hereditary predisposition. Especially if the heritability is stronger among immediate family members, especially if the mother has breast cancer, the risk of the daughter is 2 to 3 times higher. This category belongs to the high-risk group, and experts suggest that this high-risk group should have regular check-ups on their own, early diagnosis, early detection, and early detection.
5.Stomach cancer
Some stomach cancers do have a genetic predisposition!
Director Yang Qiang said that among all gastric cancer patients, 5% to 10% belong to hereditary gastric cancer, that is, the genes inherited by their parents. The largest proportion of gastric cancer is diffuse because it is an autosomal dominant disease.
It is generally accepted that if there are at least two people in a family or two generations, one of whom is younger than 50 years old. Hereditary gastric cancer may be considered in all patients with diffuse disease. If you are in such a family, then you must be careful.
1.Targeted prevention
For those who have had cancer in the family, special attention should be paid to targeted prevention, so that the relevant physical examination should be carried out once a year.
In particular, additional cancer screening is done and vaccines can be used to prevent cancers such as cervical cancer. Early prevention, early detection and early resolution can help reduce the probability of cancer and better protect your health. 
2.Pay attention to food hygiene
The food you eat must be cooked thoroughly, eat less takeout and fast food, and cook more at home. When the family eats, the meal system should be divided, and the tableware should be disinfected regularly.
Arrange three meals a day reasonably to ensure that there are vegetables in each meal;Cooking food at low temperatures, such as steaming and stewingCook food with less oil, salt and sugar, and eat more whole grains.
3.No smoking or drinking
There are many carcinogens in cigarettes, and hundreds of carcinogens will be produced after combustion, such as tar, carbon monoxide, nicotine, etc.
Regular smoking increases the risk of lung cancer, esophageal cancer, and stomach cancer. Regular excessive alcohol consumption can also cause serious damage to the body, and in severe cases, it can also cause stomach cancer and liver cancer.
4.Intensify your workouts
When preventing cancer, it is necessary to strengthen exercise, many people do not exercise enough and gradually become obese, and their physical fitness will decline after lack of exercise, and many diseases are prone to appear when the immune system is reduced, and cancer may also be the development of other small problems.
Therefore, we should be aware of the importance of exercising, and use our free time to choose sports that suit you to strengthen your body, promote circulation and metabolism, and naturally maintain your health. If you don't exercise enough and your physical fitness is too poor, serious diseases will come to your door.
Hematology tests: including routine blood tests, liver and kidney function, cardiac function and other routine tests.
Imaging examination: including B-ultrasound, CT, magnetic resonance, bone scan and other examinations, ultrasound can be checked every 1-2 months, CT can be checked every 2-3 months, magnetic resonance can be checked every 3 months, and whole body bone scan can be checked every six months or 1 year.
Endoscopy: such as gastroscopy, colonoscopy, nasopharyngeal endoscopy, etc., through which pathological specimens can be obtained.
Pathological cytology: including immunohistochemical examination of pathological specimens, cytology to find cancer cells, etc.
The above are the common methods of cancer screening in hospitals, and friends can get a cancer screening once a year.
If we are unfortunate enough to have cancer, the sooner it is detected, the sooner it is detected, the better the cancer will be controlled. Don't worry too much and be afraid, since it has happened, you must face it calmly and go to the hospital for a check-up in time.
