乳腺癌是由突变引起的,突变引起细胞周期凋亡问题,导致细胞异常增殖。性别(女性)和年龄(年龄增长)是乳腺癌[3]的两个主要危险因素。男性也会患乳腺癌。根据统计观察,在美国,每8名女性中就有1人在一生中患上乳腺癌。它是仅次于皮肤癌的美国女性最常见的癌症之一。建议20岁及以上女性至少每3年进行一次临床乳房检查。建议40岁以上的女性每年进行乳房x光检查。通过对乳腺异常细胞生长的分析,准确判断乳腺癌并予以确认。细针穿刺、芯针穿刺和手术活检是乳腺癌确诊的方法之一。患乳腺癌的女性死亡率更高。它们仅次于肺癌。0期乳腺癌的5年生存率为93%,IV期生存率为15%。死亡率高的原因是癌细胞的转移。癌症是细胞不受控制的生长。

有许多因素可能导致癌症,如遗传、生活方式、感染和环境。有100多种不同类型的癌症。美国有数百万人患有癌症。根据美国癌症协会(ACS)的数据,美国有一半的男性和三分之一的女性在他们的一生中已经或将要患上癌症。乳腺摄影筛查用于原发性乳腺癌的诊断。此外,癌症可以通过在显微镜下观察患者的细胞或组织样本来诊断。对样本细胞DNA、RNA和蛋白质的检测有助于未来的诊断。目前,癌症的诊断和预后有了明显的改善。治疗方法,如手术、化疗、放疗等,已被用来治疗癌症患者。在发展个人个性化治疗方面取得了进展。癌细胞可能进入血液或淋巴管,扩散到身体的其他部位,形成新的肿瘤,这就是癌症转移。由癌症引起的死亡中有90%是由转移性[2]引起的。

Breast cancer is caused due to mutation that causes issues in apoptosis of the cell cycle leading to abnormal proliferation of the cells. Gender (being a woman) and age (growing older) are two major risk factors for breast cancer[3]. Men also develop breast cancer. In America, according to statistical observations, one of eight women are found to develop breast cancer during their lifetime. It is the one of the most common cancer in American women next to skin cancer. Clinical breast exam is suggested at least every 3 years for women aged 20s and above. Annual mammographic screening is suggested for women in aged 40s and older. Accurate determination of breast cancer and confirmation is done through analysis of the abnormal cell growth in breast. Fine needle aspiration, core needle aspiration and surgical biopsy are some of the methods used to diagnose breast cancer definitively. Women who have developed breast cancer have higher rates of mortality. They are next to lung cancer. The 5-year survival rate for stage 0 breast cancer is 93% while the survival rate for stage IV is 15%. The reason for the high mortality rates is due to metastasis of Cancer cell.Cancer is uncontrolled growth of cells.

There are many factors that may cause cancer, such as heredity, lifestyle, infections and environment. There are more than 100 different types of cancers. Millions of people in America have suffered from cancer. Based on data from American Cancer Society (ACS), half of men and one-third of women in America already or will develop cancer in their lifetime. Mammographic screening is used for primary breast cancer diagnosis[1]. In addition cancer can be diagnosed by observing cell or tissuing samples from patients under a microscope. Tests of DNA, RNA and proteins of sample cells can help in future diagnosis. Nowadays diagnosis and prognosis of cancer have significantly improved. Treatments, such as surgery, chemotherapy, radiation therapy and other methods, have been used to treat cancer patients. Progress has been made towards developing individual personalized therapy. Cancer cells may get into bloodstream or lymph vessels to spread to other part of body and form new tumor, which is called cancer metastasis. 90% of deaths that caused by cancer is a result of metastasis[2].
