February 4 - World Cancer Day

February 4 - World Cancer Day. By this date, scientists have prepared the good news: in the first MGMU them. Sechenov developed a vaccine against cancer.

The vaccine is designed to treat already infected, rather than preventive health care. But first things first. No wonder they say: people with cancer die not from disease but from the treatment. Strong antitumor drugs often kill not only cancer but also healthy cells. But there is a safer approach - do not veer rights "poison", and make the immune system to fight the disease. As her whip and incite a tumor? On this question the scientists until recently had no answer. For example, when the virus enters the cell, it finally collapses, go out proteins that contain information about him, and, as on a silver platter, presented with this information the immune system.

She thought: "Aha, here the virus. We must kill him. " Treachery of tumor cells that information about it or do not leak out or pops up in part. Therefore, the immune system may miss the enemy, not even trying to compete with him. Hence, scientists have decided you need this information to convey to the immune system. From the tumor have been providing proteins that contain information about it, and enter back person.

Such developments in the U.S. began back in the 80's. Twentieth century. A recently published the results of tests on patients. Vaccine to cope with the tumor better than chemotherapy, did not cause severe disorders in other organs, but ... There were two problems. First: the vaccine were able to cook for only 50% of patients who participated in the study. If the tumor is small, then the right amount of drugs out of it can be done.

Second: the reason for the same cancer, say, a kidney, a severe vaccine works great, with average does not help at all, and when the lungs again effective. Russian scientists were able to circumvent these restrictions. They suggested: the vaccine does not always work, because information on the tumor is removed, not all. Proteins that hoarding "dirt" on her and that Americans are isolated from the tumor, made artificially. Thus decided to both problems.

According to the Russian method to get the same amount of vaccine required is 4 times smaller amount of tumor tissue. The experiments showed that: a new drug significantly reduces the growth of melanoma, prostate cancer and breast cancer. And there is real hope that very soon it can be applied to patients.
