Recent research conducted by the M S Ramaiah University of Applied Sciences in Bengaluru highlights alarming findings regarding the health risks associated with the use of smokeless tobacco, particularly chewing tobacco. The study, which involved 120 adults and is published in the Journal of Indian Association of Public Health Dentistry, sheds new light on how age and tobacco use interact to heighten the risk of oral cancer.
The study reveals that individuals over the age of 60 who utilize smokeless tobacco face a staggering 19.5 times higher risk of developing oral cancer compared to their non-using counterparts. This underscores the critical role that age plays in the development of cancer, as longer exposure to carcinogenic substances increases the likelihood of cellular damage.
Notably, the research indicates that oral cancer is not exclusively a male issue. Both men and women using smokeless tobacco across age groups are equally susceptible to developing oral cancer, challenging the long-held perception that tobacco-related health issues predominantly affect men.
Smokeless tobacco users have nearly 13 times the odds of developing oral cancer compared to those who smoke. While traditional smoked tobacco (like cigarettes and beedis) has well-documented links to various forms of cancer, the study points out that, intriguingly, a statistically significant association with oral cancer was not established for older adults who smoked.
The consumption of betel quid combined with raw tobacco significantly increases the risk, showing more than a 21-fold increase in oral cancer risk.
The risks are further exacerbated by the frequency of tobacco use. Those consuming smokeless tobacco more than five times a day face an alarming 39-fold increase in their risk of developing oral cancer. Additionally, prolonged use, specifically over 20 years, correlates with a nine-fold increase in cancer risk.
The implications of these findings are profound, particularly for public health initiatives aimed at reducing tobacco use. With the results indicating an urgent need for targeted prevention campaigns, especially among older adults and women, there is a clear call for increased awareness regarding the risks of both smokeless and smoked tobacco.
Moreover, healthcare professionals are urged to advocate for cessation programs that specifically address the unique challenges faced by the elderly population who may have been using these products for decades. As the study demonstrates, there is a clear evolutionary relationship between age and the genetic accumulation of changes leading to cancer, compounded by tobacco use.
