Increased tobacco smoke exposure positively correlates with a wide variety of cancers including those of lung, breast, pancreas, and prostate cancer. There are about 250 chemicals present in tobacco that have been linked to cancer. Smokeless tobacco, in the form of chewed tobacco leaves, snuff, and betel quid, has also been linked to oral and pancreatic cancers. Recent efforts to decipher mechanisms by which tobacco-derived carcinogens induce various cancers have provided profound insights about signaling pathways that are perturbed by these compounds, leading to oncogenic signaling. This special issue collates reviews and research articles that provide insights about tobacco-induced cancers at molecular, clinical, and epidemiological level. Emphasizing the use of tobacco as a global health concern, Oppeltz et al. provide a detailed review highlighting the trend towards increased tobacco use and the increasing cancer burden in developing countries. Developing countries, such as Taiwan, may indeed be at risk which is underscored by the study of Lin et al., who evaluated a prospective study cohort and found that habitual cigarette smokers, alcohol consumers, and betel quid chewers have a higher risk of contracting oral cancer. This study finds an alarming 40-fold risk of developing oral cancer in individuals who have all the above habits than controls. The risk of cancer is not limited to smokers but also affects individuals who are indirectly exposed to tobaccoderived carcinogens. However, the link between paternal smoking and childhood leukemia is not yet clearly established. Using meta-analysis, an interesting review article by Liu et al. draws a link between paternal smoking and childhood acute lymphoblastic leukemia. Pancreatic cancers have been linked to tobacco use. A research article by Lochan et al. further implicates family history as an important factor promoting cancers among smokers. The authors find that individuals with a family history of malignancy are at an increased risk of pancreatic cancer. Furthermore, individuals with a family history of malignancy and who smoke appear to require a lesser degree of tobacco exposure for the development of pancreatic cancer. To curb the use of tobacco, it is necessary to provide professional smoking cessation aid. However, smoking cessation intervention should be tailored depending on the population and ethnicity, and behavioral and cultural differences should be taken into account. A study by Delnevo et al. indicates the heterogeneous nature of tobacco use among South Asian immigrants in the USA. The study drives an important point of segregating tobacco users depending on their country of origin, and not just grouping them as “Asians,” for a more reliable understanding into the behavior of tobacco use in this population. A short clinical report by Mazza et al. emphasizes the need for smoking cessation clinics in comprehensive cancer centres to benefit smoker cancer patients.
