Targeted therapy is usually a kind of chemotherapy that targets unique molecular discrepancies among most cancers and typical cells. The 1st targeted therapies blocked the estrogen receptor molecule, inhibiting the growth of breast cancer. A different frequent instance is The category of Bcr-Abl inhibitors, which are employed to treat Continual myelogenous leukemia (CML).

癌症的症状多样，除可引起局部压迫和阻塞等症状外，还可因浸润和转移而导致相应的临床表现，有时会出现贫血、发热、体重下降、夜汗、感染、恶病质等全身表现。

The results that result depend on cancer's sort and site. Handful of signs or symptoms are distinct. Many often arise in people who produce other circumstances. Most cancers is often hard to diagnose and may be deemed a "terrific imitator".[33]

放射線治療（也稱放療、輻射療法）是使用輻射線殺死癌細胞，縮小腫瘤。放射治療可經由體外放射治療（英语：exterior beam radiotherapy）或體內近接放射治療。由於癌細胞的生長和分裂都較正常細胞快，藉由輻射線破壞細胞的遺傳物質，可阻止細胞生長或分裂，進而控制癌細胞的生長。不過放射治療的效果僅能侷限在接受照射的區域內。放射治療的目標則是要儘可能的破壞所有癌細胞，同時盡量減少對鄰近健康組織影響。雖然輻射線照射對癌細胞和正常細胞都會造成損傷，但大多數正常細胞可從放射治療的傷害中恢復。因此通常在臨床上，醫師與放射專家會小心計算需要的放射線劑量，同時放射治療也會分成許多次進行，讓健康的組織在每次輻射線照射的間隔中能有機會恢復。

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。

第二步——增生，突变后的细胞及其后代看起来仍然正常，但它们繁殖过多，这种 情况被称为增生。数年后，百万分之一的细胞（粉色）遭受另一种突变，这种突变 进一步放松了对细胞生长的控制。

Chemotherapy is definitely the cure of cancer with one or more cytotoxic anti-neoplastic medications (chemotherapeutic brokers) as part of a standardized routine. The expression encompasses a number of medications, which happen to be divided into wide classes like alkylating agents and antimetabolites.

The real key innovation in this article lies in the usage of protein cage nanoparticle-based mostly programs. These techniques are engineered to carry signals that attract NK cells directly to the tumor, beating on the list of important problems in cancer immunotherapy: making sure that the immune cells uncover and attack just the cancer cells without having harming healthful tissue.

Genetic alterations can arise at different ranges and by diverse mechanisms. The gain or lack of an entire chromosome can arise through mistakes 癌症 in mitosis. Extra common are mutations, which are changes while in the nucleotide sequence of genomic DNA.

Individuals who endure most cancers establish a second primary cancer at about twice the rate of Individuals under no circumstances diagnosed.[208] The greater danger is considered for being because of the random possibility of producing any most cancers, the likelihood of surviving the 1st most cancers, the identical hazard elements that generated the first most cancers, undesired Uncomfortable side effects of managing the first most cancers (notably radiation therapy), and far better compliance with screening.[208]

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。

与其他方法一起，可延缓病变进展、改善症状，对肛管癌、卵巢癌、乳腺癌、膀胱癌、喉癌、骨肉瘤、直肠癌、胃癌、基底细胞癌等疗效确切，对食管癌、非小细胞肺癌、鼻咽癌、恶性间皮瘤、子宫内膜癌、胰腺癌、前列腺癌等可能有价值。

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。

神经毒性：中枢神经损伤会有偏瘫、失语、痴呆等症状，外周神经损伤有肢端感觉异常、肌无力、肌肉萎缩等表现。
