Rezumat

Worldwide, breast cancer is the leading type of cancer in women, accounting for 25% of all cases (it is more than 100 times more common in women than in men). The decisive issue for the successful treatment is the early-stage diagnostics.  A number of screening tests are used for diagnostics, including clinical mammography, genetic screening, ultrasound, and magnetic resonance imaging. All these methods are rather expensive - because (at least) a two-year frequency of repetition should be ensured. Additionally, more frequent mammograms include a small, but significant increase in breast cancer induced by radiation used.  We propose extension of breast self-exams (eventually, at home) - using affordable, non-invasive and efficient method. It can serve as a preliminary signal (alarm) - for the subsequent, eventually more precise investigation. The method uses native usual symmetry of the breast - respectively, the probability of appearance of absolutely synchronic irregularities on both sides is practically zero.  The reflective-absorptive microwave properties of the tumor-affected breast obligatory differ from the intact one. By means of microwave parameters control of the reflected and transmitted waves - for each breast apart and, especially, in comparison - it is possible to detect any intrinsic (interior) changes, anomalies in the breast (usually, there occurs a lump in the unhealthy breast). Different tumor-detection schemes could be used. We pay special attention to resonance-sensitive reciprocal (reversible) scheme - inclusively because it could be integrated with mobile (cell) phone, equipped with the respective interface and application soft (Fig.1). The possibility of the efficient utilization of the microwave generator (obligatory ―implanted‖ in each cell phone), together with the remote (eventually, on-line) interpretation of the measurements‘ results - is an important advantage, offered by modern information and communications technologies (ICT). Additionally, microwaves can serve for the selective hyper-thermal treatment of the breast cancer – due to the possibility of ensuring the desired electro-magnetic field in the sample (breast). We elaborated the method of electromagnetic field distribution calculation for the sample, placed in the rectangular waveguide (see the above formula and Fig.2). Special field-corrective cylindrical layers and inserts could be used, combined with waveguide rotation, if necessary. Preliminary full-scale heating process simulation (on models) is elaborated. Also on-line non-invasive temperature control is provided.
