美国作业代写:治疗癌症

癌症是由于细胞生长异常引起的最致命的疾病之一。通过突变改变DNA序列从而改变基因表达过程是癌症的根本原因。这种突变是由一些外部因素引起的,比如暴露在紫外线下,或者其他致癌物质,比如烟草。DNA甲基化是由突变引起的,在突变中甲基被加入到DNA的胞嘧啶和腺嘌呤中。目前,化疗是目前最常见、应用最广泛的癌症治疗方法。纳米医学,使用最新的纳米技术用于许多医学应用。根据Heim和Mitelman(2015)的研究,纳米医学已经被证明在治疗和预防癌症方面比其他疗法更有效。用于纳米医学的药物是用纳米测量的,因此可以精确地靶向于癌症的部位而不产生太多的副作用(Stacey, 2013)。

为了正确治疗癌症,有必要从肿瘤形成的早期阶段对癌症进行诊断。然而,目前的医疗技术很难在早期就发现癌症(Butterworth et al. 2010)。然而,目前有多种癌症治疗技术。手术是移除肿瘤最常见的方法之一,因此可以防止肿瘤扩散到身体的其他部位。化疗或放疗、激素治疗和免疫治疗是最广泛应用的癌症治疗方式。在化疗过程中,许多抗癌药物如多西紫杉醇、多氧柔比星、环磷酰胺等都被纳入体内,以抑制细胞增殖。根据癌症类型,如乳腺癌、前列腺癌或肺癌,使用药物。许多策略都是通过药物在体内的结合来实现的。这种治疗是与其他治疗方式一起提供的,比如放射治疗。

Cancer is one of the most deadly diseases caused due to abnormal cell growth. Change in the DNA sequence by mutation and thereby altering the genetic expression process is the root cause of cancer. This mutation is caused by several external factors like exposure to UV light, or other carcinogenic compounds like tobacco. DNA methylation occurs because of the mutation, in which a methyl group is added to the cytosine and adenine of DNA.At present, chemotherapy is the most common and widely used treatment for cancer. Nanomedicines, uses the latest nanotechnology for many medical application. According to Heim & Mitelman (2015), nanomedicines have proven effective in treating and preventing cancer compared to other form of treatments. The drugs used in the nanomedicines are measured in nanometers and thus can be targeted accurately at the site of cancer without much side effects (Stacey, 2013).

For treating cancer properly, it is necessary to diagnose the cancer from the early stage of tumor formation. However, with the present medical technology it is difficult to detect the cancer from an early stage (Butterworth et al. 2010). Nevertheless, there is multiple therapy technique present for cancer treatment.Surgery is one of the most common methods used for removing tumor, and hence preventing it from spreading to other body parts. Chemotherapy or radiation therapy, hormonal therapy and immunotherapy are the most widely used form of cancer treatment. In chemotherapy treatment, many chemical that are anti-cancer drugs like docetaxel, doxorubicin, cyclophosphamide etc are incorporated in the body to inhibit cell proliferation. Depending on the type of cancer like breast cancer, prostate cancer or lung cancer, drugs are used. Many strategies are there through, which the drug is incorporated in the body. This treatment is provided along with some other form of treatment like radiation therapy.
