Prospective study of all the gall bladder cancer in our hospital over 18 months analysing how the epidemiological factors are influencing the disease. Incidence-Four cases per 100,000 populations per year. The peak incidence was in 41 to 50 years group (49.20 %). Male to female ratio was 1:3.8. Majority (69.84 %) were in lower socio-economic group. 61 out of 63 patients (96.62 %) were non-vegetarians. 60.34 % and 19.04 % patients weighed between 50 and 55 kg and 55and 60 kg respectively (p = 0.003). Male smokers had significantly higher risk (p = 0.000 1). Gall stones were present in 45 out of 63 cases(71.42 %).45 out of 63 patients were typhoid carriers (p < 0.05). Pain abdomen was the commonest complaint (87.30 %), followed by pallor, lump in right upper quadrant, nausea & vomiting and jaundice in 71.42 %, 69.84 %, 66.66 %, 31.74 % patients respectively.
