Cancer is terrible in the first place because for a long time it does not give any particularly noticeable symptoms or there are signs, but they are so harmless at first glance that a person writes them off for something else. At the same time, it is no secret to anyone: the earlier an oncological disease is diagnosed, the greater the chances of a successful cure. Doctor Alexey Vodovozov told how much time can pass between the moment when a person is healthy and the moment when he develops the first stage of cancer.
According to the expert, malignant tumors develop at different rates. For example, pancreatic cancer and mesothelioma progress very quickly. And there are such neoplasms that doctors discover after the death of a person at an autopsy, and the tumor did not give any symptoms during life.
Every fourth breast cancer, according to statistics, also does not show any signs, and it is already found during the examination. Therefore, from a state of complete health to the first stage of cancer, in theory, a whole life can pass.
It is also difficult to determine the shortest time period for tumor development, since this parameter depends on a large number of factors. In addition, when a person is diagnosed with first-degree cancer, he is most often interested not in when he got the disease, but how much is left to live, the doctor notes.
With the most aggressive type of oncology with the highest mortality – pancreatic cancer – the five-year survival rate is only 11.5%, with mesothelioma – 12%, with gallbladder cancer – 19.4%. And doctors do not have exact data on how long each of these pathologies takes.
According to Vodolazov, scientists are still continuing to study carcinogenesis. Now there is data on the results of observation of people in whom cancer was found during screening. One of the six developed over the three years between two consecutive screenings.
