Scientists have found out that the breast feeding preventive effect is extended on those women who have given birth to children in the age after 25.
According to the earlier researches, the women who had several children before 25 years, had breast cancer less often. The birth of the child after 25 years, on the contrary, is considered to be a risk factor.
Giske Ursin and his colleagues from the University of Southern California (USA) have managed to prove, that breast feeding will neutralize the risk connected to a late birth of the child.
Authors of new work have analysed the data on women in the age after 55 years among whom there were 995 patients with an invasive breast cancer. It was found out, that breast feeding reduces risk of cancer regardless of the age in which women gave birth to a child. Scientists consider, that this fact is especially important, after all even if the woman has several children, the risk is reduced only if the first child has been given birth in an early age.
According to statistics, 25 years are middle age of a first child birth in the USA.

Dissemination of tumor cells and efficiency of anticarcinogenic therapy can be fixed with the help of the tiny particles implanted into an organism.
American scientists have developed a method of joining microparticles (which can be seen during scanning) to a tumor.
Their purpose is to connect these particles with tumor cells for a long time.
Today determination of a correct doze of an anticarcinogenic medicine and revealing, whether it works correctly, is a great challenge.
Traditional analyses and blood tests can not show precisely the concentration of drugs in a tumor.
The project suggested by Massachusetts Institute of Technology will allow doctors to look “on the inside” of a tumor, using microscopic particles made of the iron oxide and covered with carbohydrates which reminds starch on a structure.
New technology offered by Massachusetts Institute of Technology has preliminary character and has never been tested on people.

Scientists have conducted researches and found out that mobile phones nevertheless can lead to development of brain cancer. The chances of disease development increases after long use, namely, ten years of mobile phone conversations. Presumably, the cause of the disease is in permanent wireless signal.
About 3,3 thousand healthy and more than 1,5 thousand patients with a brain cancer took part in the research. Among them 220 persons proved to use mobile phones for more than ten years. Resting on this information researchers came to a conclusion, that people which use this achievement of technique take 1,3 times higher chances of brain cancer development than those who does not use it.
Nevertheless, for the time being scientists are not going to sound the alarm, as all the information is based on polls and demands well-founded scientific confirmation.

30 years scientists of the Institute of nuclear physics (Russian Science Academy) spent for developing cancer treatment by means of ion beam. Recent completion of these researches can apply for sensation. Scientists have managed for the first time in the world to receive an ion beam of only 0,5 mm which can very precisely “operate” a tumor. This method of malignant tumors destruction has no analogues in the world. Authors of a new technique name it “an ionic scalpel”, as it kills cancer cells not affecting healthy tissues.
The idea of a method is simple: the stream of the charged particles - carbon ions, penetrates into the affected tissues and destroys sick cells.
The idea to use “an ionic scalpel” has engrossed scientists all over the world for a long time. For example, the special medical center is engaged in developing the similar problem in Japan. They have been working over the similar methods, but till now nobody managed to implement these theoretical preconditions in practice.
The Russian scientists managed to solve one of the most important radiotherapy problems, which are used today for cancer treatment. Use of x-ray devices for this purpose does not allow to concentrate the maximal energy on a tumor and in the process of radiation treatment healthy tissues are killed as well.
