Cancer cases in the State capital that saw world's worst industrial disasters have more than tripled among men and more than doubled among women between 1988 and 2007.
A 19-year-long study, conducted by the Indian Council of Medical Research (ACMR), has found that overall, cancer in men in all sites increased by 3.4 times while in women, the increase was 2.5 times.
Significantly, the study that compares cancer patterns in MIC (Methyl Isocyanate) affected and MIC unaffected areas between 1988 and 2007 found that cancer incidents in men living in MIC affected areas of Bhopal increased by 72% during this period. While 95.86 men per 100,000 population in MIC affected areas of Bhopal were suffering from cancer in 1988, the number stood at 164.82 men per 100,000.
The increase in cancer cases was in fact higher among men in MIC unaffected areas of Bhopal 79%. While 87.76 men per 1,00,000 population in MIC unaffected areas were cancer stricken in 1988, the number had increased to 157.23 men per 100,000 population in 2007.
The trend in women was, however, the opposite. The increase in cancer cases among women living in MIC affected areas was 115% compared to 82% increase among women living in MIC unaffected areas.
In MIC-affected areas, 89.56 women per 100,000 women were suffering from cancer in 1988, which increased to 192.39 women in 2007. In MIC unaffected areas, 95.95 women were suffering from cancer in 1988 compared to 174.97 women per 100,000 population in 2007.
Overall, among men, cancer of the tongue saw a 3.8 time increase, mouth saw a 3.3 times increase, hypopharynx saw a 2.6 times increase, oesophagus a 3.3 times increase and lung 2.4 times increase between 1988 and 2007. Among women, mouth cancer cases saw a three times increase and oesophagus a 1.7 times increase in the same period. The study will be made public soon.
While 24.05 people per 1,00,000 population in MIC affected areas had cancer in 1988, it increased to 31.92 people per 1,00,000 population in 2007. In MIC unaffected areas, TRC stood at 20.02 per 1,00,000 population in 1988 which increased to 30.55 per 100,000 population in 2007.
