Husband and wife in their 70s, daddy got lung cancer
When the mother-in-law checked, it was also lung cancer!
Mother and daughter, the mother has breast cancer,
Years later, my daughter also had breast cancer!
The younger brother accompanies the brother of colorectal cancer to see a doctor,
The doctor suggested that my brother have a colonoscopy,
It was found that there is also colorectal cancer...
"Cancer in couples"
"Mother-daughter cancer"
"Brother Cancer"
……
It is not uncommon clinically
That's what's going on
Is it like the flu
Can cancer also be contagious?
There is now a general consensus in the scientific community
Cancer cells are not contagious
The essence of cancer is caused by the mutation of normal cell genes into cancer cells, crazy replication, and infinite proliferation.
Cancer cells are very fragile, and once they leave the human body, they will quickly apopt to die without nutrient supply, and they have no ability to "run" to other organisms.
Occasionally, cancer cells pass into the body of others, and they will be immediately recognized and destroyed by the immune system of others, and it is impossible to cause new cancer.
According to medical research experiments, even if cancer cells are implanted into other normal people, they cannot survive.
Since it is not contagious
Why does it appear
What about "husband and wife cancer", "mother-daughter cancer" and "brother cancer"?
Although the cancer itself is not contagious
But it is possible to inherit
Breast cancer and colorectal cancer do have a great correlation with genetic factors, and are prone to multiple family occurrences.
However, it has nothing to do with infection, and it is recommended that patients do family genetic screening according to the guidance of doctors and intervene as soon as possible to achieve the purpose of early treatment.
But certain carcinogenic factors can be "contagious"
"
Some bacterial and viral infections are predisposing factors for certain cancers
Infection of Helicobacter pylori, which is a causative factor in stomach cancer.
Hepatitis B and C viruses transmitted through blood and sexual contact are important causative factors of liver cancer.
Human papillomavirus (HPV), transmitted through sexual contact, is responsible for most cervical cancers...
Some common lifestyle habits are predisposing factors for certain cancers
Bad habits. For example, husband smoking and wife smoking "second-hand smoke" are all associated with lung cancer.
Unhealthy eating habits. He prefers to eat high-salt or pickled foods, eats foods contaminated with Aspergillus aflatoma, and also has the eating habit of eating high-fat, high-salt, and low-fiber foods, which is related to the occurrence of stomach cancer.
Influencing factors related to the geographical environment are predisposing factors for certain cancers
Some relatives in some families may be gathered in a certain area and affected by the regional environment.
Some regional people, because they like pickles, pickled products, and like to eat hot rice, resulting in a higher incidence of esophageal cancer and stomach cancer.
The lack of a certain trace element or a trace element exceeding the standard in some areas can also lead to a high incidence of cancer.
Emotional causes are also predisposing factors for certain cancers
Some people in the family suffer from cancer, and other family members, whether mentally or physically, have to bear huge pressure, resulting in a sharp decline in immune function, accelerated development of cancer that has occurred in the body, and the phenomenon of cancer accumulation.
But in fact, these are not caused by cancer infections
Just a concentrated manifestation of carcinogenic factors!
Blocking "family members with cancer"
The key is: early detection and early intervention
If cancer is detected in the family, other family members should be vigilant and should go to the hospital for screening in time if necessary to prevent the problem before it happens.
The 8 most common methods of early screening for major cancers
1. Lung cancer: CT examination
2. Liver cancer: B ultrasound + blood test for alpha-fetoprotein
3. Breast cancer: breast B ultrasound + molybdenum target
B-ultrasound examination
Molybdenum target examination
4. Colorectal cancer: colonoscopy
5. Stomach cancer: gastroscopy
6. Esophageal cancer: endoscopy
7. Prostate cancer: color ultrasound + PSA examination
8. Cervical cancer: TCT, colposcopy and pathological diagnosis
With the current level of medical care improving
Early detection, early intervention
As a result, the cure rate and survival of many cancers have been significantly improved
Therefore, there is no need to smell cancer discoloration and panic
Good mood is also a good medicine to deal with cancer!
