ALSO CAUSES CANCER
 TOBACCO NOT ONLY CAUSES CANCER
BUT ALSO OTHER DISEASES
CAUSES – BETELNUT
 BETELNUT CONTAINS CARCINOGENS
 THE NUTS KEPT BURRIED IN THE
GROUND FOR LOND PERIOD LEADS
TO THE GROWTH OF FUNGUS WHICH
IS CARCINOGENIC
 PEOPLE CONSUMING BETELNUT ALSO
HAVE THE HABIT OF CONSUMING
TOBACCO
CAUSES - ALCOHOL
 ALCOHOL CONSUMPTION LEADS TO
CANCER OF ORAL CAVITY, PHARYNX,
LARYNX, ESOPHAGUS, STOMACH,
LIVER
 PEOPLE WHO DRINK ALSO SMOKES
FURTHER INCREASING THE RISK OF
DEVELOPING CANCER
CAUSES – FAT/FIBRE
 HIGH INTAKE OF FAT (ANIMAL)
INCREASES
THE
RISK
OF
DEVELOPING CANCER (BREAST AND
COLON)
 DIETARY FIBRE OF PLANT ORIGIN
HAS A PROTECTIVE ROLE AGAINST
CANCER
CAUSES – BARBEQUED FOOD
 HIGH FAT AND HIGH PROTEIN FOOD
WHEN
GRILLED
AT
HIGH
TEMPARATURE
PRODUCES
A
CHEMICAL KNOWN TO BE HAVING
CARCINOGENIC EFFECT
 HIGHLY BROWN AND CHARRED FOOD
HAS CANCER CAUSING COMPOUNDS
CAUSES - POLLUTION
 AIR POLLUTION – MAY ALSO CAUSE
CANCER (ASBESTOS)
 INDUSTRIAL WORKERS ARE EXPOSED
TO VARIOUS CHEMICALS WHICH ARE
KNOWN TO BE CARCINOGEN
CAUSES – WATER POLLUTION
