乳腺癌是女性最常见恶性肿瘤之一, 其发病呈上升和年龄变小趋势, 在许多大中城市乳腺癌已占妇女恶性肿瘤死因的首位。乳腺癌的发生发展是多基因共同作用的结果。随着细胞分子生物学技术的发展, 研究发现基因突变或调控失常是正常细胞转变为恶性细胞的关键。通过对乳腺癌相 Breast cancer is one of the most common malignant tumors in women. The incidence of breast cancer is rising and becoming younger. Breast cancer has taken the lead in the cause of death of malignant tumors in many large and medium-sized cities. The development of breast cancer is the result of multi-gene interaction. With the development of cell molecular biology technology, the study found that genetic mutations or regulatory disorders is the key to normal cells into malignant cells.
