Among the tobacco related cancer sites in New Delhi, cancer of lung was the most common (23.3%) followed by cancer of tongue (16.9%) and mouth (14.6%). Interestingly in females, cancer of lung accounted for 26.0% followed by mouth (17.8%) and oesophagus (17.7%).

In 2008, tobacco related cancers constituted for 39.2% of all cancers in men and 11.5% of all cancers in women, the report stated.

“About 90% of the lung cancers are tobacco related cancers. The number of tobacco related cancers has gone up significantly since 2006-07 cancer registries due to excessive chewing of tobacco and ‘paan masala’.

The number of tongue and mouth cancers has also increased over the last few years,” said Dr PK Julka, Head of Radiation Oncology, Dr BR Ambedkar Institute Rotary Cancer Hospital, AIIMS.

Meanwhile, crude mortality rate (CMR) per 100,000 persons for lung cancer among males is 1.5 and 1.7 in 2008 and 2009 respectively. However, in women, CMR per 100,000 persons was highest among breast cancer cases with 1.3 and 1.4 in 2008 and 2009 respectively.

The report further stated that in 2009 the five leading sites of cancer for males were lung (9.3%), tongue (6.8%), prostrate (6.7%), mouth (5.8%), larynx (5.6%). Among women, breast cancer was the leading site with 27.1% followed by cervix (11.4%), ovary (6.9%), gallbladder (6.6%) and uterus (3.4%).

“Breast cancer has overtaken cervix cancer in the past few years due to the change in lifestyle among women belonging to post-menopause age group,” he added.

The number of cancer cases registered in Delhi in 2009 was 15244. Among them 8122 (53.3%) were men and 7122 (46.7%) were women.
