2. Among various diseases, cancer has become a big threat to human
beings globally. As per Indian population census data, the rate of
mortality due to cancer in India was high and alarming with about
900000 existing cases by the end of the last century.

3. Cancer is the second most common disease in India responsible for
maximum mortality with about 0.3 million deaths per year. This is owing to
the poor availability of prevention, diagnosis and treatment of the disease.
All types of cancers have been reported in Indian population.
Cancer is caused by majorly two kinds of pollution.
1) Air pollution
2) Water pollution

5. WHAT DO WE KNOW??
 Many different water pollutants increase cancer
risk.
 Exposure to these pollutants can occur by
drinking contaminated water or bathing,
showering or swimming in it.
 Disinfection, a process that protects our health
from other diseases also causes cancer.
 Given the vast number of people who get their water from outdated treatment and
delivery systems, Public and private water supplies can be contaminated by
pollutants from hazardous waste sites and industrial, commercial, agricultural and
domestic sources.

7. WHAT CAN WE DO??
 Update water treatment facilities and delivery infrastructure to reduce
disinfection by-products.
 Enhance watershed protection programs to reduce contamination of
surface waters.
 Reduce pollution by promoting green chemistry, alternatives
assessment, and the sun setting of cancer-contributing substances.
 Ensure that current drinking water standards truly protect public
health.

8. AIR POLLUTION AND CANCER

9. WHAT DO WE KNOW??
Air pollution is a mixture of gases and
particulates, the exact composition of which
depends upon the pollutant sources and
meteorological conditions of a given area.
Major sources of air pollutants can
include industrial sources, power plants and
motor vehicles.
Air pollution can increase cancer risk, among them:
1) Occupational studies demonstrating increased risk of lung cancer among
railroad, bus garage, trucking, and dock workers exposed to diesel exhaust.
2) Studies examining populations near specific air pollution point sources such as
waste incinerators or metal smelters.

11. WHAT CAN WE DO??
 Increase enforcement of current regulatory standards.
 Continue to improve those standards based upon monitoring data and
related health studies.
 Support the development and adoption of innovative, non-polluting
technologies.
 Expand, support, and incentivize the use of public transportation
systems.

12. Smoking: Another cause for cancer!!

13. Passive smoking
Chemicals in cigarette smoke enter our blood stream and can then affect the
entire body.
This is why smoking causes so many diseases, including at least 14 types of
cancer, heart disease and various lung diseases.
 Non-smokers exposed to second hand
tobacco smoke increase their risk of
lung cancer by 20-30%.
 Passive smoking can cause premature
death in non-smokers.
 Sidestream smoke may become
more toxic as it goes from being
fresh to aged. www.mummyandcuties.com

14. HOW CANCER DEVELOPS??
Cancer risk is influenced by exposures to many different factors, including
agents that can contribute to the disease in work environments, the general
environment, diet, genetic inheritance, reproductive factors, and other
lifestyle factors. Low levels of exposure depend not only on what a person is
exposed to, but also the timing of exposures.
