CANCER MORTALITY

IN INDIA

On behalf of the Million Death Study Collaborators, and in partnership with

Tata Memorial Hospital (Mumbai, India), St. John’s Research Institute

(Bangalore, India), IARC (Lyon, France) and SEARO (Delhi, India) of WHO and the Centre for Global Health Research (Toronto, Canada)

LANCET PRESS RELEASE: WEDNESDAY, MARCH 28, 2012

Key findings

• About 0.6 Million (M) or 6 Lakh cancer deaths in 2010

• Over 70% of cancer deaths occurred during ages 30-69 years

(200,000 men and 195,000 women)

• At ages 30-69 years, the three commonest fatal cancers

– Men: oral, stomach, and lung

– Women: cervical, breast and stomach

• Tobacco-related cancers are over 40% of male and nearly 20% of female cancers

• Cancer death rates are similar in rural and urban areas

• Huge variation in cancer death rates across states- partly due to tobacco, and partly for reasons awaiting further discovery

• Cancer death rates 2-fold higher in the least educated compared to the most educated adults

• Cervical cancer death rates far less in Muslim women than among Hindu women

What’s new about this research?

• First large, nationally-representative study of cancer mortality in India, reflecting both urban and rural areas

• Previous cancer estimates have relied mostly on cancer registries in cities, but

70% of Indians live in rural areas

• Provides distribution of cancer deaths by area, educational level, and religion

How was the study done?

• Nationally representative sample (Sample

Registration System)

• 6,671 of these small areas randomly chosen from all parts of India (each with about 1000 people per area)

How was the study done?

800 Registrar General of India field workers interviewed 122 thousand families of people who had died in 2001-2003

Written reports each coded independently by at least two physicians to attribute a probable cause of death (i.e., cancer)

Cancer deaths grouped into broadly similar categories (i.e., oral, lip and pharynx; lung and trachea, etc.)

How was the study done?

Calculated proportion of all cancer deaths by age, gender, and cancer type within the study

Combined with national 2010 UN totals of deaths, and 2007-2009 state-specific SRS death rates

CGHR.ORG/CANCER

Twitter: CGHR_org

Produced national and state estimates of rates and number of cancer deaths for 2010

Key results

• 7137 of 122 429 study deaths were due to cancer, meaning about 600,000 cancer deaths across the whole of India in 2010.

• Some 71% (395,000) of cancer deaths occurred in people aged 30-69 years (200,100 men and 195,300 women).

• At ages 30-69, cancer deaths are:

 8% of the 2.5 million total male deaths

 12% of the 1.6 million total female deaths

Implications

• Most cancer deaths in India are avoidable as they occur at younger ages and present late after cancer starts

• Most importantly, higher tobacco taxes reduce cancer

• Strategies to vaccinate, screen, and treat women with cervical cancer also work.

• Early detection of cancer dramatically improves the prospect of cure

• Big differences suggest more research on why common cancers are rare in parts of

India
