A Review Of 癌症

臨床實驗,是在癌症病患身上進行新的治療方法的實驗,希望找出更好的方法治療癌症,協助癌症患者恢復健康。臨床實驗測試範圍包含新的治療藥物,新的手術方法或放射治療方式,重新組合不同的療法,或發展全新的療法,如基因療法。

The enhanced knowledge of molecular biology and mobile biology because of cancer study has triggered new treatment plans for cancer given that US President Richard Nixon declared the "War on Cancer" in 1971.

人乳头瘤病毒检测(包括人乳头瘤病毒核糖核酸和信使核糖核酸检测),这是宫颈癌筛查的首选方式;

Some systemic signs or symptoms of cancer are because of hormones or other molecules produced by the tumor, often known as paraneoplastic syndromes.

畸胎瘤是性腺或胚胎剩件中的全能细胞发生的肿瘤,常发生于性腺,一般含有两个以上胚层的成分,结构混乱,也有良性和恶性之分。

允许其快速增长。基因突变可以命令细胞快速增长和分裂。这将产生许多具有相同突变的新细胞。

[a hundred and five] Each individual of such alterations regulates gene expression without having altering the underlying DNA sequence. These adjustments may perhaps continue being through cell divisions, endure for numerous generations, and can be considered as such as mutations.

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。

雖然癌症症狀的治療並不被視為是癌症的治療方法,但對於癌症病患的生活品質有重要的幫助,也能用來評估病患是否能進一步接受其他治療。儘管所有醫師都能夠使用藥物來減輕或抑制疼痛、噁心、嘔吐、腹瀉、出血及其他癌症患者常見的症狀,舒緩治療的進一步發展對於有這一方面的需求的病患仍然是相當重要的。

出生后发生的基因突变。大多数基因突变会在您出生后发生,并且不会被遗传。有多种因素会导致基因突变,例如抽烟、辐射、病毒、致癌化学物质(致癌物)、肥胖症、激素、慢性发炎和缺乏运动。

Elective abortions usually are not necessary and, for the commonest types and phases of most cancers, never Enhance the mother's survival.

Cancers usually are named applying -carcinoma, -sarcoma or -blastoma to be a suffix, Together with the Latin or Greek phrase for your organ or tissue of origin as the root. One example is, cancers of your liver parenchyma arising from malignant epithelial cells known as hepatocarcinoma, when a malignancy arising from primitive liver precursor cells is known as a hepatoblastoma plus a cancer arising from fat cells is called a liposarcoma.

癌症复发。癌症幸存者有癌症复发的风险。有些癌症比其他癌症更容易复发。请咨询医生如何降低癌症复发的风险。治疗后,医生可能会为您设计一份随访护理计划。该计划可能包括在治疗后的几个月和几年里定期进行扫描和检查,以寻找癌症复发的迹象。

If 癌症 a significant error occurs, the ruined mobile can self-destruct as a result of programmed mobile Dying, termed apoptosis. In the event the error Regulate procedures fall short, then the mutations will survive and become handed alongside to daughter cells.
