三级预防是治疗后的康复,防止病情恶化,提高生存质量,减轻痛苦,延长生命。
避免暴露于紫外线辐射(这主要源于阳光暴晒和人工晒黑设备)和/或采取防晒措施;
而根據癌症發展的程度,又可分為零、一、二、三、四期等,及早期與晚期,通常零到一期算是早期,但在不同癌症中每期的定義和治療方法都有所不同,確實的分期仍應參考美國癌症聯合委員會的定義。
DNA repair inhibition is proposed to become a predominant mechanism in large steel-induced carcinogenicity. Also, Recurrent epigenetic alterations of your DNA sequences code for small RNAs known as microRNAs (or miRNAs). miRNAs usually do not code for proteins, but can "focus on" protein-coding genes and lessen their expression.
这里需要注意另外一个概念——肿瘤。肿瘤是局部组织细胞增生所形成的新生物。 肿瘤分为良性肿瘤和恶性肿瘤两大类。良性肿瘤不会扩散或侵入附近组织。切除后, 良性肿瘤通常不会再长出来,而恶性肿瘤有时会。然而,良性肿瘤的体积有时可能 很大,有些会引起严重的症状或危及生命,比如脑部的良性肿瘤。恶性肿瘤可分为 癌和肉瘤,癌是指来源于上皮组织的恶性肿瘤。癌性肿瘤会扩散或侵入附近的组织, 并可以扩散到身体的远处形成新的肿瘤(这一过程称为转移)。许多癌症形成实体瘤, 但白血病是血液癌症不会形成实体瘤。如果还是没能理解肿瘤和癌症的关系,可以看 下图。在后续的文章中我们将针对各类不同的癌症进行深入的讨论与分析。
Big-scale mutations include the deletion or achieve of the part of a chromosome. Genomic amplification happens whenever a mobile gains copies (frequently 20 or even more) of a little chromosomal locus, usually made up of one or 癌症 more oncogenes and adjacent genetic product. Translocation occurs when two independent chromosomal locations turn into abnormally fused, normally in a characteristic place.
免疫療法是利用人體內的免疫機制來對抗腫瘤細胞。已經有許多對抗癌症的免疫療法在研究中。目前較有進展的就是癌症疫苗療法和單株抗體療法,而免疫細胞療法則是最近這幾年最新發展的治療技術。
准确诊断癌症对采取适当有效的治疗措施必不可少,因为每种癌症类型都需要特定的治疗方案。治疗通常包括手术、放疗和/或全身性治疗(化疗、激素治疗、靶向生物治疗)。适当选择治疗方案既要考虑癌症又要考虑接受治疗的个体情况。在限定时间内完成治疗方案对于实现预期的治疗效果很重要。
Which remedies are employed will depend on the sort, site and quality on the cancer together with the affected individual's health and Tastes. The treatment intent might or might not be curative.[citation desired]
Compared with cure which is aimed at specifically killing cancer cells, the first purpose of palliative treatment is to enhance Standard of living.
消瘦:因肿瘤消耗患者体质、营养摄入不足、并发感染等情况,患者体重不断下降,晚期会极度消瘦。
