It is reported ' Reporter Wang XueFei) August 28, one research that Science issue brief on, cancer it shifts to be one later period incident in the the intersection of cancer and progress. Cancer cell spread arrive new place in body, might earlier than the past time thought. Discovery this, to why after initial tumour has already got the treatment for a long time some breast cancer, the problem of shifting etc. will also happen and provide the new explanation. It is the disease process causing most cancer patients death finally that cancer is shifted. The academia thinks that it is the incident of one later period in the cancer progress to shift, namely sent tumour cells originallying just starts the cancer gene after accumulating a series of genetic alteration. But KatrinaPodsypanina and their animal experimental result which the colleague launched, scholar of American, brief on, the possible beginning of transformation of tumour is early to disease. They keep the dormancy state in the transformation place of the organ, until the cancer gene is changed body into the cancer cell at the time of start. Researchers have injected the normal mammary gland cells dealt with through the experiment for the little mouse, make different time after injection it, activate among them some cancer genes (or tumour gene) . Discover, these normal mammary gland cells can advance to the lung through the blood circulation, and can survive there and is as long as 16 weeks, but does not express any tumour genes. Cell these activation, will not grow in the lung actively in the intersection of tumour and gene. KatrinaPodsypanina proposes, surveys every step of the transfer process of cancer, including the transformation of those normal cells, may make scientist find, destroy, cause cancer shift new tactics of cells.
