Specific therapy is usually a method of chemotherapy that targets certain molecular variances in between most cancers and standard cells. The main qualified therapies blocked the estrogen receptor molecule, inhibiting the growth of breast cancer. Yet another popular instance is the class of Bcr-Abl inhibitors, which happen to be used to deal with Serious myelogenous leukemia (CML).
註解：癌細胞將於所到之處繼續失控的繁殖。舉例：若肺癌細胞轉移到肝臟，則肝臟將出現不斷增生的肺部細胞（不具肺功能），且此細胞具有入侵正常肝臟細胞的能力，導致肝功能不斷降低；反之，不具入侵能力但失控繁殖的細胞，稱為良性腫瘤。
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 indicators of most cancers are attributable to hormones or other molecules produced by the tumor, known as paraneoplastic syndromes.

制定标准和工具，以指导筹划和实施针对成人和儿童癌症的预防、早期诊断、筛查、治疗、姑息治疗和生存关怀措施；
In sporadic cancers, deficiencies in DNA fix are at times brought on by a mutation inside a DNA mend gene but are much more usually caused by epigenetic alterations that minimize or silence expression of DNA mend genes. This is often indicated within the figure with the third stage. Lots of studies of hefty metal-induced carcinogenesis present that these major metals induce a discount in expression of DNA repair service enzymes, some as a result of epigenetic mechanisms.
Not like remedy that is certainly aimed toward directly killing most cancers cells, the primary intention of palliative care is to further improve quality of life.
Even though epigenetic alterations are present in cancers, the epigenetic alterations in DNA restore genes, creating reduced expression of DNA repair proteins, might be of specific great importance.
