乳腺癌是女性最常见的恶性肿瘤之一,也是导致女性肿瘤患者死亡主要疾病之一,在我国,乳腺癌的发病率呈逐年上升趋势。因此,对乳腺癌早期诊断、准确分期、判断疗效等显得尤为重要。目前,对于乳腺癌的诊断主要依靠乳腺X线摄影术、B超及MRI。乳腺X线摄影术由于敏感性偏低,即使临床体检能够扪及的乳腺癌病灶(大于1cm)仍有10%的漏诊[1]。
Breast cancer is one of the most common malignant tumors in women and one of the leading causes of cancer death in women. In China, the incidence of breast cancer is on an upward trend year by year. Therefore, the early diagnosis of breast cancer, accurate staging, to determine the efficacy is particularly important. At present, the diagnosis of breast cancer mainly depends on mammography, B ultrasound and MRI. Because of the low sensitivity of mammography, 10% of missed breast cancers (> 1 cm) are palpable even in clinically detectable breast cancers [1].
