Bangladesh is grappling with the largest mass poisoning of a population in the world due to contamination of drinking water with naturally occurring inorganic arsenic. It is estimated that 75 million people of 59 (out of 64) districts are at risk of drinking contaminated water with arsenic above 50g/L. Long term exposure to arsenic causes cancers, including skin, lung, and bladder. Tis is a randomized prospective study to see the prevalence of skin cancer from arsenic afected area of Bangladesh, as well as their variation by geographical area, age, gender, location on the body, and socioeconomic conditions, in outpatient department of plastic surgery unit of Bangabandhu Sheikh Mujib Medical University (BSMMU). A total of 960 patients with skin cancers comprised of 528 males and 432 females were selected for the study from January 2004 to December 2015. In this 12-year study, we found squamous cell carcinoma, basal cell carcinoma, melanoma, and Merkel cell carcinoma to be associated with the ingestion of arsenic contaminated ground water. Tis is a refection of a small part of the total national scenario of devastating result of arsenic mediated cancer in terms of skin malignancy. Tis study will help the future researchers who are contemplating to work on arsenic induced health problem. 1. Introduction Arsenic contamination of ground water in Bangladesh is reported to be the worst problem in the world in terms of afected population [1, 2]. Survey data from 2000 to 2010 have demonstrated that an estimated 35 to 77 million Bangladeshi people, especially in rural area, have been chron- ically exposed to arsenic through drinking water and daily food [3–5]. Before 1970s, people in this country used surface water for drinking and daily activities. Te surface water was pathogen laden and as a result they sufered from several types of diarrheal diseases in epidemic manner. To solve this problem, since 1970s, the government and other international organizations introduced shallow tube wells. Te people got the apparent beneft but the hidden problem was discovered years later. Te water from shallow tube wells (depth of 10- 70m) contains arsenic in toxic level, which causes a lot of hazards to the human body.
