MUMBAI: Confronted with a near-doubling of mouth cancer rates since the mid-1980s, policy-makers and tobacco-control activists have cause to worry whether the ban on gutka is too-little-too-late. The cancer registry data published by Gujarat Cancer Research Center over the 20-year period spanning 1985 and 2006, when analyzed by Mumbai's Healis-Sekhsaria Institute of Public Health, reveals a near-doubling of oral cancer rates across different age-groups.
The cohort (group) of males who attained the age of 34 in 1995 suffered 2.1 oral cancer cases per lakh males between the ages of 25 and 34 (10-year-span). The cohort of males that was 10 years older (i.e. which attained the age of 34 in 1985) had suffered only 1.2 oral cancer cases per lakh between the ages of 25 and 34. The as-yet-unpublished analysis (which is an update of a study published in Journal of Medical Association in 1999 titled Mouth Cancer in India - A new Epidemic, included cancer of the cheeks, lower and upper jaw, hard and soft palate and gums in males only.
This steep trend continued as the youngest cohort attained the age of 44 in 2006; it suffered 15.9 oral cancer cases between the ages of 35 and 44. Again, this was close to double the rate of older age group (8.5 oral cancer cases per lakh males between 35-44), and nearly three times the cancer rate (5.6 oral cancer cases) of another age group that was 20 years older.
