压迫：如食管癌、甲状腺癌等压迫气管，需要及时气管切开；若脑转移或脑肿瘤压迫中枢神经，需及时进行颅内减压处理等。
One particular plan about why people with cancer are blamed or stigmatized, known as the just-planet fallacy, is blaming most cancers to the patient's steps or attitudes permits the blamers to get back a way of control.
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。
Indicators of cancer metastasis count on the location on the tumor. When cancer starts, it produces no signs. Signs and indications seem given that the mass grows or ulcerates.
治療某些白血病和淋巴瘤則需要使用高劑量的化療或全身放射治療。這樣的治療方式是先將患者原有的骨髓細胞完全破壞，避免進行骨髓細胞移植時發生排斥作用。進行骨髓移植之後，依靠患者本身的復原能力，重新進行造血功能。移植的來源除了接受親屬或配對符合的捐贈者之外，也可將病患本身的骨髓細胞以及周邊造血幹細胞（英语：peripheral blood stem mobile）先取出存放待日後移植所需，稱為自體移植（英语：autologous transplantation）。
梗阻：与瘤体增大堵塞正常腔道有关，如胃肠癌梗阻引发呕吐、排便困难，胰头癌胆汁排出受限引发黄疸等。
肿瘤，癌和癌症的关系 正常組織轉變成腫瘤需經一連串的過程。從最初期的細胞增生，多半可藉由身體本身的防禦機制加以清除或保持穩定。到成為一團腫塊的良性腫瘤，此時身體已無法自立將其去除，而只能選擇共存。但是也並非所有良性腫瘤都會轉變成為惡性腫瘤。惡性腫瘤是指當增生的細胞侵入周遭組織，並獲得新生血管供應養分後，開始快速生長且轉移到其他組織的時候，也叫做癌症。
第一步——基因突变，当正常细胞（米色）中的某些细胞（橙色）发生基因突变， 使其在正常状态下增殖的倾向增加时，肿瘤就开始发展了。
Those that endure most cancers create a 2nd primary cancer at about two times the speed of These under no circumstances diagnosed.[208] The improved hazard is considered for being mainly because of the random possibility of producing any most cancers, the chance of surviving the initial cancer, precisely the same hazard elements that made the 1st most cancers, undesired side effects of treating the first most cancers (particularly radiation therapy), and much better compliance with screening.[208]
Taller people have an elevated hazard of cancer simply because they have a lot more cells than shorter people. Due to the fact peak is genetically determined to a significant extent, taller individuals have a heritable increase in most cancers threat.[88]
Treatment is mostly the same as for non-Expecting Girls. Nonetheless, radiation and radioactive medication are Ordinarily averted during pregnancy, particularly when the fetal dose may exceed a hundred cGy. In some instances, some or all treatment plans are postponed right up until following start When the most cancers is diagnosed late in the pregnancy.
Radiation therapy is Utilized in about fifty percent of conditions. The radiation might be both from inside sources (brachytherapy) or external resources. The radiation is most commonly reduced Power X-rays for dealing with skin cancers, though better Strength 癌症 X-rays are utilized for cancers throughout the system.[193] Radiation is often applied Besides operation and/or chemotherapy.
Deficient expression of DNA mend proteins as a consequence of an inherited mutation can improve most cancers challenges. People today having an inherited impairment in almost any of 34 DNA mend genes (see report DNA mend-deficiency problem) have enhanced cancer risk, with a few defects making certain a 100% life span prospect of cancer (e.
