The alternative to excision of cancer tumours is offere ...

Instead of carrying out of surgical operations on excision of cancer tumours physicians of the USA suggest to implant new instruments which are capable to destroy cancer cells into a body of the person.

The group of immunologists and bioengineers of the Harward university has framed a bioengineering disk from porous biologically decomposed polymer which has only 8,5 mm in diameter and can be implanted under a skin on any site of a body how implant contraceptives under a skin on an arm of the woman. The disk is impregnated by dendritic cells and the "cancer" antigens carrying the information on what cancer cells should be destroyed immune system. After disk implantation interaction of antigens with the dendritic cells transferring the information to immune system which thanks to it starts to distinguish cancer cells begins and to develop specific cells for the purpose of their destruction. Thus implanted the disk stirs up activity of immune system and as a result there is an "aim" destruction of a cancer tumour.

During researches scientists implanted these disks to mice with such serious kind of a cancer, as a melanoma. The spent treatment has led to long remission and larger life expectancy of an appreciable part of experimental animals. The report on these researches has been placed on November, 25th in the electron version of Science Translational Medicine medical magazine.

Results of one more research, spent to employees of Argonnsky national laboratory and Medical school Prittskera of the Chicago university, show, that for cancer treatment, possibly, it will be possible to use and such newest technologies, as nanomagnets. Researches were conducted while only in laboratory conditions.

Using nanodisks in the/thickness about 60 nanometers, made of an iron and nickel alloy, researchers framed in them so-called "a magnetic whirlwind" - a magnetic field which power lines represent concentric circles. Then they included the external variable magnetic field causing fluctuation of disks that led to destruction of membranes of cancer cells and they die. To achieve it though while only in a test tube, researchers used within 10 minutes a field frequency of all in some tens hertz. As scientists have explained, fluctuation nanodisks starts process of destruction of cancer cells. Details of this work are resulted in magazine Nature Materials for November, 29th.
While these innovative methods of treatment of oncologic diseases are investigated in laboratory conditions, the cancer continues to remain one of the main reasons of a mortality in the USA, taking the second place after cardiovascular diseases. Only last year its victims of a steel over a half-million of Americans
