Is nasopharyngeal cancer contagious? Can any expert explain it Thank you!

Most patients with nasopharyngeal cancer carry a virus called Epstein-Barr virus, commonly known as "kissing virus", which is an important killer of nasopharyngeal cancer.

Transmission route of nasopharyngeal carcinoma Epstein-Barr virus.

Saliva exchange. Kissing is the most common mode of transmission. Other routes of transmission include sneezing, coughing, sharing utensils and blood transfusions.

Infected people will have headache, fever, enlarged liver, dehydration, diarrhoea, and the symptoms will generally last for 2 to 4 weeks, but the symptoms will last longer in people with weakened immunity. The virus is more common in young people around the age of 20, so experts caution not to kiss strangers to reduce the chance of nasopharyngeal cancer.

In general, nasopharyngeal carcinoma is not contagious like other pathogens, but the presence of EBV will aggravate the induction of nasopharyngeal carcinoma, which does not fundamentally indicate that nasopharyngeal carcinoma is infectious.

According to Mendel's genetic positioning, nasopharyngeal carcinoma is not a hereditary disease, but the epidemiological research suggests that genetic background plays a very important role in the pathogenesis of nasopharyngeal carcinoma. His research focuses on human leukocyte antigens, sister chromatid transit, chromosomal fragility and aberrations.

According to the investigation, genetic factors play a certain role in the incidence of nasopharyngeal carcinoma, which has a certain racial susceptibility and familial clustering. Some brothers, sisters or parents also suffer from nasopharyngeal cancer, and some brothers have nasopharyngeal cancer one after another. In the 70s of the 20th century, some studies found that nasopharyngeal carcinoma is related to human leukocyte antigen (HLA).

Nasopharyngeal carcinoma is predominantly seen in yellow people. Southern China (Guangdong, Guangxi, Hunan, Fujian) and some countries in Southeast Asia have the highest incidence of nasopharyngeal cancer in the world. Guangzhou, Foshan, Zhaoqing and other regions in Guangdong Province have the highest incidence rate, with 18 27 per 100,000 males and 8 9 females.

Even if people in high-incidence areas move to distant places, such as Northeast China, their descendants still maintain a high tendency to develop the disease, which indicates that the occurrence of nasopharyngeal carcinoma has obvious racial sensitivity. In addition, a tendency to familial clustering can be found in both high-risk and low-incidence areas. For example, in the general survey, it was found that 10 out of 49 people in three generations of a family had cancer, and 9 of them had nasopharyngeal cancer.

It can be thought that genetic factors play an important role in the development of nasopharyngeal carcinoma.

The formation of nasopharyngeal carcinoma requires both triggering and contributing factors. These factors come into play because of the environment. An individual's lifestyle and dietary habits are closely related to the development of nasopharyngeal cancer.

Therefore, it is necessary to maintain scientific living habits to avoid the occurrence of nasopharyngeal cancer to the greatest extent.

Hopefully this will help you.

Not contagious. But there is a tendency to run in families.

**Unclear, but with the following factors Epstein-Barr virus, fumes, dust, toxins, family history.

Epstein-Barr virus can be retested regularly.

Don't worry, it's not contagious. Even if you kiss every day, it's okay... But I don't believe there will be that day.

He won't be transfected to you, but if he's in poor health, he'll get infected himself.

No. At most, it's a bad lifestyle. Or he has EBV on him that could infect you.

No, cancer cells can't get to you.

There is a phenomenon of ethnic and familial clustering of nasopharyngeal carcinoma patients, such as the southern Chinese living in other countries, who still maintain a high incidence of nasopharyngeal carcinoma, which suggests that nasopharyngeal carcinoma is hereditary

Hello, according to the report of Professor Xia Tingyi, vice chairman of the Radiation Oncology Committee of the Chinese Medical Association, domestic pancreatic cancer patients who emigrated to foreign countries still have a higher incidence of nasopharyngeal cancer in the first generation than foreigners, and the second generation is also higher, and it will be flat in the third generation. Therefore, nasopharyngeal carcinoma has a certain hereditary nature.

1. The final diagnosis of all nasopharyngeal carcinoma is based on pathological diagnosis, although clinical symptoms, signs, X-ray, CT and serological diagnosis suggest nasopharyngeal carcinoma, there must still be a pathological clear diagnosis. There are several methods of biopsy for nasopharyngeal carcinoma:

1) Transoral bite biopsy (the most common method).

2) Transnasal nasopharyngeal biopsy.

3) Fine needle puncture in the nasopharynx.

Your results suggest a nasopharyngeal cyst and nasopharyngeal CA is not considered, so you should not worry, and if you are worried, you can have a biopsy.

This is not a good way to say, and further examination is required.
