The early symptoms of esophageal cancer are not obvious, and most of them are in the middle and late stages when diagnosed, which is tricky to treat and the symptoms are very dangerous. China is one of the countries with the highest incidence of esophageal cancer, with more than 220,000 new cases of esophageal cancer and about 200,000 deaths each year, making esophageal cancer a major killer threatening human health.
Middle and late stage esophageal cancer symptoms are dangerous and threaten patients’ lives seriously
Symptoms of esophageal cancer in the middle stage: difficulty in swallowing is the main symptom. Few patients may have hoarseness due to laryngeal nerve compression caused by esophageal cancer invading local lymph nodes; if esophageal cancer causes local ulcers, symptoms of anemia, gastrointestinal bleeding and blood in stool may appear. The symptoms are sometimes mild and sometimes severe, and progress slowly. A considerable number of patients with esophageal cancer have lost the opportunity of surgical treatment when they visit the doctor.
Late stage symptoms of esophageal cancer: severe patients may develop symptoms such as cachexia, emaciation, anemia and severe malnutrition due to long-term difficulty in eating. Some patients even have violent choking and coughing when swallowing water or food due to long-term inability to eat and drink water, which triggers respiratory system infection and leads to cachexia state and seriously threatens patients’ life due to no better treatment measures. If there is metastasis to liver, brain and other organs, jaundice, fluid accumulation in abdomen and coma may appear.
Did you know that the latent period of cancer can be as long as decades?
According to statistics, the transformation of normal cells into cancer cells under the effect of various carcinogenic factors (such as harmful chemicals) is a gradual process, which usually takes a long time, 15-20 years on average, and some may take as long as several decades. The theory that most cancers have a latent stage seems to explain why tumors are most often seen in adults over the age of 40. Early detection of cancer when it is still in the latent or early stage is very important for cancer prevention and early treatment.
Esophageal Cancer Susceptibility Gene Test
Tumor susceptibility gene testing can help high-risk people to anticipate their health conditions in advance and prevent major diseases before they occur. The esophageal cancer susceptibility gene test can enable the examinees to know their own genetic information in time and find out or determine whether they are at risk of esophageal cancer, so that they can anticipate and improve their living environment and habits to prevent or treat the tumor risk early and let the tumor cells have nowhere to hide in the latent stage.
Who need to have esophageal cancer susceptibility gene test?
1.Age over 40 years old;
2.From areas with high incidence of esophageal cancer;
3.With upper gastrointestinal symptoms;
4.Have family history of esophageal cancer;
5.Persons with pre-cancerous esophageal diseases or pre-cancerous lesions;
6.Have other high-risk factors of esophageal cancer (smoking, heavy alcohol consumption, head and neck or respiratory tract scale cancer, etc.).
Esophageal cancer susceptibility gene test: it can predict the probability of occurrence of esophageal cancer in high-risk groups, give preventive advice to the test subjects, and provide ultra-early warning for early prevention and treatment of tumors. And take preventive measures for patients, on the other hand, they can also have regular checkups against this cancer, so that if it is really cancer, it can be detected and treated as early as possible.
