At the University of Nebraska-Lincoln, experts have proposed the latest development, which will significantly increase the survival rate among patients with breast cancer. According to experts, due to the improvement of the diagnostic process, the indicators of a favorable outcome for a breast cancer will rise to 94%. It's no secret that the earlier the disease is identified, the more likely the woman to have successful treatment.
The new technology, called "electronic skin", perfectly identifies the seals in the chest, determines the shape (even if the seal is less than 10mm). Specialists managed to create a very thin sensitive film from polymers and nanoparticles, with the help of which physicians will be able to obtain more accurate ideas about the tissues of the breast.
For diagnostics, it is necessary to place the "electronic skin" over a certain area of the breast. Scientists have already tested the film by using objects located between layers of silicone, resembling a cancers, which in some way simulated breast and breast cancer. When diagnosing it is necessary to press on the film with the force with which a routine examination is carried out at the mammalogist, but the film is more sensitive than the hands of a specialist. As a result, with the help of the film, it was possible to detect a tumor of 5 mm in size, which was located under a 20 mm layer of silicone.
In addition, "electronic skin" is able to diagnose other types of cancer.
Breast cancer is the most common type of malignancy that is diagnosed among women. In one of the cancer centers in New York, experts believe that the presence of soy products in the diet can lead to accelerated growth of cancer cells. To this conclusion, specialists came after a new study in which 140 women with invasive breast cancer participated. Each patient recently had cancer of stage 1-2, and 2-3 weeks after the detection, each woman was assigned an operation to remove the tumor.
Half of the participants in the study took an additional powder that contained soy protein genistein, the second part of the experimental group took placebo. The course of admission lasted 7 - 30 days before the scheduled surgical intervention. After this, the scientists compared the samples of cancer cells taken before and after the surgical removal of the tumor. As a result, scientists found that in the expression of genes that influenced the growth of cells, there were differences. Destructive processes were observed in the group of women taking soy powder. All the research data pointed out that products with soybean content can accelerate the development of a cancerous tumor in the body. Currently, specialists do not know whether it is possible to reverse the process provoked by the soy.
It was interesting that 20% of the subjects who took soy protein had very high levels of this protein (genistein) in their blood. But to predict the reaction of the organism in each individual case on soy is rather difficult. In the group of women with high genistein levels, there have been cases when in the recruitment of genes that influenced the development, death and anomaly of cancer cells, there were obvious changes. Similar changes affected that category of women who took more than 50 grams of soybeans a day (about 4 cups of soy milk). In a group of high-risk women may come from Asian countries, since there are the most common vegetarian dishes and tofu (bean curd).
