These nanodrones are created to harness the strength of pure killer (NK) cells, which Enjoy a crucial position in your body's immune reaction versus tumors. By directing these NK cells particularly on the web-sites of tumors, the nanodrones can effectively concentrate the immune system's assault within the most cancers cells, most likely resulting in improved results for people.[270]

Cancers usually are named making use of -carcinoma, -sarcoma or -blastoma as being a suffix, Using the Latin or Greek term with the organ or tissue of origin as the basis.

許多預防癌症的想法是根據流行病學的研究而來，分析病患的資料可發現生活方式或是接觸一些環境危險因子的確與特定癌症的發生機率相關。越來越多的證據顯示，根據流行病學研究所提出的建議改善，確實可以讓癌症發病率和死亡率降低。
確診為癌症後就要進一步做癌症屬於哪一期之分期檢查，觀察是否有轉移，並定期追蹤以免癌症復發，以便醫師擬定治療方向。（延伸閱讀：癌症診斷的目的與方法）
癌症患者治療和研究的進展限於醫師間各自的研究與測試，直到第二次世界大戰時期，許多醫學研究中心發現同一種疾病在不同國家間的發生率差別相當大，也促使各國的公共衛生組織互相通報疾病及流通醫院治療的資料，直到今日仍然是廣為各國採用。日本醫學界觀察到廣島和長崎原子彈受害者的骨髓完全被毀壞。他們認為放射線可能也可用來治療有問題的骨髓，這項發現開啟了使用骨髓移植治療白血病的想法。

The central role of DNA harm and epigenetic defects in DNA fix genes in carcinogenesis The classical look at of most cancers is usually a list of health conditions pushed by progressive genetic abnormalities which include mutations in tumor-suppressor genes and oncogenes, and in chromosomal abnormalities. A task for epigenetic alterations was discovered while in the early 21st century.[103]
