in fiecare minut, in fiecare secunda, o femeie este diagnosticata cu cancer mamar

In fiecare an, zeci de mii de femei sunt diagnosticate cu cancer de san, boala invalidanta si cu o mortalitate crescuta in randul femeilor aflate la menopauza. Cu cat inaintezi in varsta, cu atat riscul de a dezvolta un cancer mamar creste. Mult mai probabil vor fi afectate femeile care au rude apropiate, de sange (mama, bunica, matusa, sora sau tatal), care au avut cancer de san, genital sau de testicule in antecedente, aparute inainte de varsta de 50 de ani.

in Romania exista acum metode neinvazive de diagnosticare: termografia, sonoelastografia...

"Sonoelastography is an ultrasound imaging technique where low-amplitude, low-frequency shear waves (less than 0.1 mm displacement and less than 1 kHz frequency) are propagated through internal organs, while real-time Doppler techniques are used to image the resulting vibration pattern. When a discrete hard inhomogeneity, such as a tumour, is present within a region of soft tissue, a decrease in the vibration amplitude will occur at its location. This forms the basis for tumour detection using sonoelastography. For three-dimensional (3D) imaging the acquisition of sequential tomographic slices using this technique, combined with image segmentation, enables the reconstruction, quantification and visualization of tumour volumes. Sonoelastography and magnetic resonance images (MRI) of a tissue phantom containing a hard isoechoic inclusion are compared to evaluate the accuracy of this method. The tumour delineation from sonoelastography was found to have good agreement with the tumour from MRI except for a bleeding at one of its ends. Although sonoelastography is still in an experimental phase, the principles behind this imaging modality are explained and some practical aspects of acquiring sonoelastography images are described. Results from a 3D sonoelastography reconstruction of a tissue mimicking phantom and an ex vivo whole prostate specimen are presented."
