The 癌症 Diaries
癌症篩檢,是希望在一般大眾身上提早找出潛在未發現與早期無症狀的癌症。所進行的測試必須適合廣大民眾能夠負擔,並且安全,無侵入性而且不易有假陽性結果產生。一旦發現癌症的跡象,更精確的後續檢驗,或使用侵入性手術取得組織切片以確定篩檢結果則是必要的。Some systemic signs and symptoms of most cancers are attributable to hormones or other molecules produced by the tumor, known as paraneoplastic syndromes.
The enhanced idea of molecular biology and mobile biology resulting from cancer analysis has led to new therapies for most cancers due to the fact US President Richard Nixon declared the "War on Most cancers" in 1971.
大脑和神经系统问题。癌症会压迫到附近的神经,导致身体某一部位疼痛和丧失功能。累及大脑的癌症可能导致头痛和卒中样体征和症状,例如身体一侧无力。
上述中各種症狀都有可能由其他的疾病引起,癌症不一定是產生這些症狀的主因,確切原因仍需要鑑別診斷診察。

The afflicted genes are divided into two broad groups. Oncogenes are genes that promote mobile development and replica. Tumor suppressor genes are genes that inhibit mobile division and survival. Malignant transformation can happen in the formation of novel oncogenes, the inappropriate about-expression of normal oncogenes, or with the less than-expression or disabling of tumor suppressor genes.
Engraving with two sights of a Dutch girl who had a tumor removed from her neck in 1689 Cancer has existed for all of human record.[226] The earliest written record concerning cancer is from c. 1600 BC inside the Egyptian Edwin Smith Papyrus and describes breast cancer.[226] Hippocrates (c. 460 BC – c. 370 BC) described several kinds of most cancers, referring to them with the Greek term καρκίνος karkinos (crab or crayfish).[226] This title arises from the appearance on the Lower surface area of the solid malignant tumor, with "the veins stretched on all sides as the animal the crab has its toes, whence it derives its title".

化学致癌物,例如石棉、烟草烟雾成分、酒精、黄曲霉毒素(一种食品污染物)、 砷(一种饮水污染物)、烷化剂、酰化剂、亚硝胺类、芳香胺、环氧化物等;巴豆油、 激素、酚类等物品,会增加致癌物质的效应。

癌症治療會有許多後遺症,過程十分不易,因此治療後的照顧相當重要,包括疼痛控制、改善食慾、心理調適等,需要不同醫療團隊的合作,提高癌症病人的生活品質。(延伸閱讀:不是放棄治療!剖析緩和與安寧照護的真相)
根據組織診斷可判定腫瘤的生長程度,其病程的分級和其他腫瘤特徵。這樣的資訊對於判斷病患的預後情形和選擇最佳治療方式上非常有用。細胞遺傳學和免疫組織化學染色法對於提供有關癌細胞未來可能的發展情況以及選擇治療方式上,都佔有相當重要的角色。
