To study the distribution of cancers, with particular emphasis on oesophageal cancer.
Patient records for 1986-88 in the Department of Oncology, SK Institute of Medical Sciences, were searched to identify cases and types of cancer.
The Valley of Kashmir, India.
Patients with cancer resident in the valley.
The seven most common types of cancer in men were those of the oesophagus, lungs, stomach, skin, upper respiratory tract, and urinary tract. In women the most common types of cancer were those affecting the oesophagus, breast, cervix, stomach, skin, colon/rectum, and lungs. Cancer of the oesophagus was the most frequent type in both sexes, accounting for 42.9% of all types of cancer in the valley. This distribution of cancer types is strikingly different from that in the rest of India where oropharyngeal cancer is the most common form. Again, contrary to the trend in India as a whole, cervical cancer is not a leading type of cancer in the valley and is less frequent even than cancer of the breast in the women.
The preponderance of oesophageal cancer was attributable to the local practice of drinking boiling hot salt tea. Universal male circumcision in the majority community in the valley was considered to be partly responsible for low cervical cancer frequency.
研究癌症的分布情况，尤其着重于食管癌。
检索了SK医学科学研究所肿瘤学系1986 - 1988年的患者记录，以确定癌症病例和类型。
印度克什米尔山谷。
居住在该山谷的癌症患者。
男性中七种最常见的癌症类型为食管癌、肺癌、胃癌、皮肤癌、上呼吸道癌和泌尿系统癌。女性中最常见的癌症类型为影响食管、乳腺、子宫颈、胃、皮肤、结肠/直肠癌和肺癌的癌症。食管癌是两性中最常见的癌症类型，占该山谷所有癌症类型的42.9%。这种癌症类型的分布与印度其他地区显著不同，在印度其他地区口咽癌是最常见的形式。此外，与整个印度的趋势相反，子宫颈癌在该山谷不是主要的癌症类型，在女性中甚至比乳腺癌的发病率还低。
食管癌的高发归因于当地饮用滚烫咸茶的习惯。该山谷多数群体普遍实行男性包皮环切术被认为是子宫颈癌发病率低的部分原因。
