The majority of patients in their tumors were found. Inquired in detail about the history and clinical examination, the majority of the masses can arrive at a correct diagnosis.
X-ray diagnosis : breast camera is a common diagnosis of breast cancer, divided into dry plate camera and low-dose-ray. Young women's breast tissue susceptible to radiation damage, while its more dense breast tissue, generally difficult to make the diagnosis and differential, so the 35-year-old following the women often do not advocate for breast camera inspection.

Ultrasound imaging examination : Ultrasound imaging examination without injury and can be repeated. Ultrasound imaging of specific tumor size often more correct and therefore can be used to compare the treatment of non-surgical methods (such as chemotherapy, radiotherapy, endocrine therapy, etc.) results.

Other Diagnostic Imaging methods thermal image inspection, near infrared scanning, CT scan, MRI screening.
Laboratory tests : cytologic and histologic diagnosis; Cytology; Fine needle aspiration cytology (needle) is increasingly being used its safe operation, rapid diagnosis. The final diagnosis of breast cancer should come from the biopsy.

Brazil invention early detection of breast cancer recurrence new method
Brazilian scientists After many years of research, recently developed an early detection of breast cancer recurrence risk and easy method has Tumor Hospital in Sao Paulo into clinical use.

According to the "St. Paul" on the 26th, the body of the p53 gene can be found DNA (deoxyribonucleic acid) replication errors and prevent an error in the cell division, and c-erbB-2 gene can promote a large number of cell proliferation. By testing was swollen <BR> tumor removed within two genes activities, we can more accurately predict early breast cancer patients with recurrence.

Gene control protein synthesis, protein activity which is also reflected in the decision protein gene activities. Brazilian scientists have invented a new method for detecting gene is not directly, but more easily detected by the detection of genes control protein synthesis, it is very simple, ordinary laboratory will be able to proceed.

Researchers use this technology on 156 breast cancer patients in the experiment. These patients have a tumor diameter of 2 cm in the following resection of cancer cells when there had not been transferred. After 50 months, those tumors within these two genes strongly activities over the patients, 87.7% of breast cancer recurrence, 43.3% of deaths. The two genes in patients with normal activities, the relapse rate and mortality rate is only 10.1% and 10.6%.

The researchers pointed out that the technology allows doctors to the patients as early as possible under different circumstances take appropriate treatment measures, and has important clinical significance. Breast cancer incidence rates in Brazil higher, every year 17,000 women die.

On clinical examination, mammography, ultrasound is commonly used in the diagnosis of breast lesions, in the differential diagnosis of benign and malignant lesions is of great help, but the final diagnosis of breast cancer has relied on in pathologic diagnosis, access to the diagnostic pathology major ways : biopsy, surgical excision biopsy. Numerous studies indicate that biopsy tumor proliferation will not increase the risk of transfer. Puncture positive results can generally be clear diagnosis, and puncture negative results, should review the situation and decide whether further surgical biopsy. After surgical biopsy confirmed as malignant, should normally be conducted within two weeks radical surgery. Conditional hospitals can of suspected breast cancer patients with tumor resection while hospitalized for frozen pathology, pathology confirmed immediately after radical surgery, thus reducing tumor metastasis and recurrence opportunities.
