It reported the first case of "infection" of human cancer
American scientists have for the first time faced with a case where a cancerous tumor was transmitted by parasites. In a study of 41-year-old man found a tumor-like cancer, but too small for the human cancer cells. It was found that these tumors are transferred from the belt of dwarf tapeworms.
According to the agency "Xinhua", a study authored by scientists from the Centers for Disease Control and Prevention United States has shown that cancer cells arising from parasite "dwarf tapeworm» (Hymenolepis nana), moved into the host - 41-year-old man whose immunity has been weakened HIV infection.
A man from the city of Medellin in Colombia went to the doctor with complaints of fever, cough, fatigue and weight loss - all of these symptoms persist for several months. The study showed that the tumor in the patient's lungs, liver, adrenal glands, lymph nodes. Growths looked like cancers, but cancer cells were too small for human cancer cells.
The results of DNA analysis amazed scientists. It was found that the cancer cells are transmitted to humans from dwarf tapeworms - dwarf tapeworm. We know that cancer can be transmitted to other animals dog, Tasmanian Devil and shellfish, but this is the first case of "contamination" from the parasites of human cancer, the researchers say. Results of the study raised concerns of physicians, people with weakened immune systems are at risk of sick of this kind of cancer. Particular risk in the less developed countries, where widespread dwarf tapeworm.
"We were amazed when we found this new type of cancer that is transmitted from person to tapeworms - said the study's lead author Myuhlenbas Atis (Atis Muehlenbachs). - It is uncommon, but, nevertheless, this parasite is spread throughout the world, and millions of people suffer from diseases such as HIV that weaken their immune system. It is definitely worth looking into. "
According to the "Xinhua", similar but unconfirmed incident occurred in January 2013, when doctors in Colombia appealed to the Centers for Disease Control United States to help in the diagnosis of unusual tumors in the lungs and lymph nodes of the patient. Tumors were similar to human cancer, but the cells were too small - about 10 times less than the human cancer cells. After dozens of tests, doctors found the dwarf tapeworm DNA in tumors man. Unfortunately, 72 hours after analysis, the patient died. We add that the dwarf tapeworm affects up to 75 million people, thus being the most common parasite.
