Breast cancer is the fourth leading cause of cancer death for Taiwanese women. X-ray mammography is currently the most effective method for an early diagnosis of the breast cancer. The existence of spicules is one of most important visual signs for breast cancer diagnosis. Spiculation is a stellate distortion caused by the intrusion of breast cancer into surrounding tissue. In general, malignant tumors appear with rough and complex boundaries or contours, whereas benign masses present smooth, round, or oval contours.In this paper, we present a technique to detect the contours of spiculated lesions from the regions of interest in a mammographic image.

中文摘要乳癌是是我国妇癌症死亡主因的第四位，乳癌诊断程序中，乳房X光摄影为临床上医生诊断乳癌的利器，在诊断乳房摄影肿瘤的影像时，可用特徵决定为良性或恶性肿瘤，良性肿瘤通常会呈现圆滑的特徵，而恶性肿瘤则呈现星状或不规则不平滑特徵，这种星状或不规则不平滑特徵组织，称为星状物肿瘤，指的是肿瘤周围的乳腺组织，因星状物往外侵犯的关系造成的变形，星状物的存在是恶性肿瘤判断的依据。

Investigations have approved that selenium is the trenchancy inhibitor of galactophore cancer, liver cancer, skin cancer, colon cancer and stomach cancer, some investigations in outside of body indicated that the induction of differentiation in a number of tumour cell lines by Retinoic acid and Sodium selenite had taken out adding effects, namely, the rate of induction of differentiation and inhibition of proliferation on malignant tumors by the associated application of two different sorts medicaments is approximately double towards by the every one.

Since there were 10 more unscreened cancer patients and 5 more cervical cancer deaths in the cytology arm than in the HPV arm and since these unscreened cancer patients predictably had higher rates of cervical cancer, more advanced stages, and less favorable outcomes, the net effect of the inclusion of the larger number of unscreened cervical cancer patients in the cytology arm was to make the cytology arm appear more like the unscreened control arm of the study.

Urologic cancer surgeons need to think about maintaining long-term kidney function, because that might ultimately affect the overall survival of these patients."The oncologic data are clear," Dr. Blute said. The cancer survival rates are identical for partial and radical nephrectomy, but these new data suggest that there might be a difference in overall survival."This is a cancer database, so we only know that these patients didn't die from cancer, but we don't know what they died from," he explained."Further study is necessary in a population of possible kidney cancer patients who have a history of smoking, diabetes, hypertension, or obesity, which are exactly the conditions that predispose to chronic kidney disease."

泌尿外科医师应该考虑维持长期的肾脏功能，因为这可能最终影响这些病患的整体存活率；Blute医师表示，肿瘤学的数据是清楚的，接受部分与全肾脏切除的癌症存活率是相同的，但这些新数据显示整体的存活率可能有差异，他解释，这是个癌症资料库，因此我们仅知道这些病患并未死于癌症，但是我们不知道他们死于何种原因；未来的研究需要针对有吸菸、糖尿病、高血压、或是肥胖病史，这些状况可能造成慢性肾脏疾病，且可能是罹患肾脏肿瘤的病患进行进一步的研究。
