HER2, belongs to the Epidermal Growth Factor receptor family, is one of The most vμlnerable oncogene in human tumor. HER2, a protein produced by a specific gene with cancer-causing potential. HER system including four epidermal growth factor receptor, Epidermal growth factor receptor is a kind of transmembrane glycoprotein with PTK activity, which have high expression in many epithelial tumour. Gefitinib (Iressa, ZD1839), a specific tyrosine kinase inhibitor that targets the epidermal growth factor receptor (EGFR), is a novel molecular-targeting antineoplastic agent.
The new drug is targeted to treat breast cancers that carry a special genetic marker, known as HER2. HER2 play an important role in the growth and survival of cancer cells. her2 combination with Cancer cell, and then Formed enzyme.
Enzymes will cause cancer cells continue to divide. breast cancer is a high incidence of tumors in women older than 40. Many women can reduce the incidence of breast cancer by the breast self-examination.
Breast self-examination does not diagnosed early breast cancer timely, The women is best to do breast examination regularly, breast X-ray mammography, ultrasound and MRI, CT scan, image positioning biopsy, nipple discharge examination can improve the early diagnosis of breast cancer. X-ray mammography can accurately diagnosed early breast cancer, X-ray mammography - accurate judgement of breast lesions benign and malignant degree. HER2-positive breast cancer patients have been diagnosed remain optimistic, Choose the best treatment options.
To understand HER2 status is very important in breast cancer patients. Research shows that HER2-positivity affects approximately 20-30% of women with breast cancer. In breast cancer patient, her2 masculine breast cancer patient's worsened speed often is higher than the negative patient.
If determined that her2 is a masculine gender, should in view of her2 gene marching song proper bead Shan Kangba to the treatment, reduce the recrudescence risk promptly.
Breast cancer patients need to do HER2 testing, diagnosis of cancer was negative or positive. HER2-positive breast cancer survival time was 1 to 3 years, and HER2-negative patients survived at least 4 to 6 years.
if check the status of HER2 in time and use the right treatment, Chances of survival of HER2-positive patients with breast cancer will be close to normal.
