Malignancy has been a constant global health concern for a number of years, resulting in significant social and economic impacts on individuals with malignancy and their families.<ref>{{cite journal | journal = Australian Institute of Health and Welfare | title = Cancer data in Australia, cancer incidence and survival by stage data visualisation | url = https://www.aihw.gov.au/reports/cancer/cancer-data-in-australia/contents/cancer-incidence-and-survival-by-stage-data-visualisation }}</ref> The risk of developing malignancy is 20.2%.<ref name = "Mattiuzzi_2019">{{cite journal | vauthors = Mattiuzzi C, Lippi G | title = Current Cancer Epidemiology | journal = Journal of Epidemiology and Global Health | volume = 9 | issue = 4 | pages = 217–222 | date = December 2019 | pmid = 31854162 | pmc = 7310786 | doi = 10.2991/jegh.k.191008.001 }}</ref> In 2018, 18 million patients were diagnosed with a malignant tumour with lung, breast and prostate being the most common form.<ref name = "Mattiuzzi_2019" /> Additionally, there were approximately 10 million mortalities due to cancer in 2020<ref name = "WHO_Cancer" /> and, there is an overall trend which demonstrated that malignant mortality has increased by 28% over the past 15 years.<ref name = "Mattiuzzi_2019" />

Lung cancer has the highest mortality rate in comparison to other forms of cancer, with the leading cause of development due to smoking.<ref name="Bender_2014">{{cite journal | vauthors = Bender E | title = Epidemiology: The dominant malignancy | journal = Nature | volume = 513 | issue = 7517 | pages = S2–S3 | date = September 2014 | pmid = 25208070 | doi = 10.1038/513S2a | s2cid = 577152 | doi-access = free }}</ref> The number of smokers in China is rapidly increasing with tobacco killing approximately 3000 people each day.<ref name="Bender_2014" /> The diagnosis of lung cancer is most common within the 50–59-year age bracket.<ref name = "Mattiuzzi_2019" /> Further, it caused 1.8 million deaths in 2020 alone.<ref name = "WHO_Cancer" />
