U.S. scientists recently published study reported that the use of nanotechnology, by comparing the cancer cells and normal cells, differences in flexibility that can help doctors improve the accuracy of cancer diagnosis.

University of California, researchers extracted from the samples of suspected cancer patients, placing them under a microscope nanoscale test. The researchers used probes to sample each of a cell to impose weak voltage, the probe head and an arm connected to the other.

Ner-2/Neu (c-erbB-2), one of the epidermal growth factor receptor, located in human chromosome 17q21, encoding a molecular weight of 18500 of the envelope protein amine P185, with a tyrosine kinase-like activity, can promote cell division and proteolytic enzyme secretion, causing increased synthesis of DNA, cancer cells grow faster, and increase exercise capacity cells, thereby promoting tumor invasion and metastasis. Many studies have shown that endocrine treatment is poor, disease-free survival and overall survival rate is low. It was suggested that c-erbB-2 overexpression and high tumor grade. There is lymph node metastasis. Phased night was positively correlated with ER, PR expression was negatively correlated, and the expression of the higher the worse the prognosis.

Breast lobular hyperplasia of breast disease female patients accounted for more than two thirds, from youth to middle age can occur. The early stages, there is breast pain, the ensuing mass, or yellow nipple discharge, the patient very nervous.

Breast lobular hyperplasia is a benign breast disease in women, common disease, is physical in nature subinvolution caused hyperplasia and normal tissue structure of the mammary gland disorders. More common in middle-aged women, often located in the outer upper quadrant of breast, very few lumps to form a clear boundary, but in the thickening of breast tissue consisting mainly of local, small nodules flu, severe cases, a sense of clumps, but the texture, flexibility, borders have generally not very clear, very little adhesion with the skin, often affecting bilateral breast. The reasons for its occurrence may be related to higher levels of estrogen, estrogen. Progestin hormones and other metabolic imbalances related to lobular hyperplasia and therefore may change with the changes in the menstrual cycle. Some patients consciously breasts pain, menstrual cramps, particularly obvious in the light those who like acupuncture. In severe cases, may apply to the axilla. Shoulder radiation, after the pain relieve menstrual cramps or disappear.

Breast cancer metastasis may be brought about in other parts of the lesion, the specific transfer is as follows:

1. Lymph node metastasis: lymph node metastasis of breast cancer the most common site for the ipsilateral axillary lymph nodes, followed by the ipsilateral internal mammary lymph node, late may be spread to the ipsilateral supraclavicular lymph nodes, or contralateral supraclavicular lymph nodes. The clinical manifestations of lymphatic metastasis can be seen the transfer of parts of lymph nodes. Quality hardware. And even integration into the group. Fixed. Axillary lymph nodes may be late venous pressure, affecting the upper extremity upper extremity edema and lymphatic flow Er Zhi. Such as the supraclavicular lymph node metastasis, may be palpable in the back of knee clavicle large number of scattered or integration into the group of mass, 0 5 ~ 5cm in diameter sizes. The transfer of early lymph node small and hard, when fusion of “sand-like feeling.”

Breast cancer and breast hyperplasia of the same point is this: Both can see breast lumps.

Breast cancer and breast hyperplasia difference is: hyperplasia of mammary glands of the breast lumps are generally more texture soft, or medium hardness, lumps, mostly bilateral multiple sizes and can nodular. Chip block or granular, activities with the skin and surrounding tissues no adhesion, tumor the size of the characters often change with the menstrual cycle and mood change as slow-growing tumor, and good hair in the middle-aged women;

After 16 years at Harvard University researchers found that if the petite women’s body weight (kg) divided by height (in meters) squared (ie, body mass index BMI), the result is less than 25, but has a D cup and above the chest, then the risk of breast cancer after menopause will be significantly larger than the A cup women.

On the currently known breast cancer are often associated with a variety of complex factors, often high fat and low dietary fiber intake of more, post-menopausal weight gain, smoking. Radioactive radiation, pesticides and other harmful stimulation, as well as genetic factors, . With the continuous advancement of medical standards, further research revealed that the occurrence of breast cancer with its own “capacity for liquor” relevant.
