Its exhibits vary from tropical rainforests to temperate wetlands, giving natural habitats for various species. The zoo's commitment to conservation, education and learning, and community engagement has made it a standout establishment during the zoological Group.

如果篩檢為陽性，或者是出現許多前述症狀、久未改善，就需進一步診斷，癌症診斷方式包括三大類：

L’utilisation huge du plastique jetable, le manque de traitement des déchets toxiques industriels mais aussi domestiques est impactent aussi bien l’air que l’eau. L'absence de traitement des eaux usées fait que le tiers de l’eau est impropre à la consommation

第五步——浸润性癌，如果基因变化使肿瘤开始侵入下层组织，并使细胞脱落到血液或淋巴中， 则认为肿瘤已变成恶性肿瘤。癌变的细胞很可能在全身形成新的肿瘤（转移）；这些可能会因破坏重要器官而致命。

机体受到多种因素的共同作用，发生基因异常改变，包括原癌基因激活、抑癌基因失活、多种基因异常的累积等，最终形成癌症。

Visitors who turn into divided from their bash can seek out help from Guest Services or any staff members discovered by Woodland Park Zoo identify tags. We endorse that all groups determine a gathering area, while in the occasion they get separated.

[one zero five] Every single of these alterations regulates gene expression devoid of altering the fundamental DNA sequence. These improvements may well continue to be as a result of cell divisions, endure for several generations, and can be regarded as similar to mutations.

多數癌症是自發性的（英语：sporadic），但是有些癌症還是與遺傳有關，通常遺傳到缺陷的腫瘤抑制基因時會有較顯著的影響和症狀。舉例而言：

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。

抽烟、饮酒、熬夜等不良习惯，以及性别、衰老和肥胖等生理因素，也是某些癌症的风险因素。

The zoo collaborates with conservation organizations throughout the world to shield endangered species and market sustainable methods. Its conservation attempts are integral to its mission to encourage men and women to treatment about and act to preserve the pure world.

Some substitute treatment options happen to be investigated and proven being ineffective but nevertheless keep on being promoted and promoted. Cancer researcher Andrew J. Vickers mentioned, "The 癌症 label 'unproven' is inappropriate for these therapies; it really is time to claim that many alternate cancer therapies are 'disproven'."[204]

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。

相反的，子宮頸抹片檢查在所有種類的癌症篩檢中則具有最好的成本效益。以公共衛生考量來看，子宮頸癌的病程發展通常十分緩慢，長達數年，又具有明顯的危險因子（性接觸），因此有相當高的機會可在癌症仍是早期時篩檢出來，最重要的是，抹片的成本很低，能夠大量推行。基於這些原因，一項癌症篩檢是否應該進行，民眾的健康改善程度和篩檢的成本與治療的風險都必須列入考慮。
