Qualified therapy is a sort of chemotherapy that targets certain molecular variances among most cancers and usual cells. The very first focused therapies blocked the estrogen receptor molecule, inhibiting The expansion of breast cancer. An additional frequent illustration is The category of Bcr-Abl inhibitors, that happen to be applied to deal with Long-term myelogenous leukemia (CML).
The improved idea of molecular biology and cellular biology resulting from most cancers investigate has brought about new treatment options for cancer given that US President Richard Nixon declared the "War on Cancer" in 1971.
A single notion about why those with most cancers are blamed or stigmatized, known as the just-planet fallacy, is the fact blaming most cancers about the patient's actions or attitudes makes it possible for the blamers to get back a sense of Handle.

安排癌症筛查检查。根据您的风险因素,请与您的医生沟通哪种类型的癌症筛查检查最适合您。
虽然医生知道哪些因素会增加患癌风险,但大多数癌症会发生于没有任何已知导致癌症的风险因素的人身上。可导致癌症风险增加的已知因素包括:
用醫學影像技術檢測癌症,也遭遇類似問題。這些醫學影像檢測技術都是成本相當高且耗費時間。由於偵測的靈敏度極高,常發現細胞病變(英语:incidentaloma),這樣的腫瘤也可以被認為惡性,而進行具有潛在危險性的治療方法。
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。
您可以通过改变这些习惯来降低患癌风险,尽管有些习惯比其他习惯更难改变。
出血:瘤体快速增大可致破裂出血,如肺癌有痰中带血、咯血等表现,胃肠癌则有呕血、黑便、血便等症状,肾癌、膀胱癌表现为血尿,妇科肿瘤则表现为阴道出血等。

筛查规划根据年龄和风险因素来选择患者,以避免进行过多假阳性研究。筛查方法的例子包括:
恶性肿瘤生长迅速,可在短时间内快速增大,为外生性或浸润性生长,影像学检查通常界限不清,常继发出血、坏死、溃疡等变化,组织病理学特征为分化差、异型性大、可见病理性核分裂像,对机体的伤害大,会破坏机体组织结构及功能,易复发、转移,致死率高。
