Cooking Oil Fumes Cause Tumor

The leading cause of lung cancer among women in the city was cooking oil fumes while men are more
likely to develop the disease from smoking,said medical experts after a five-year research study.
Doctors announced the results yesterday with analysis on some new tendencies on lung cancer. They
said patients are younger,especially women.
According to the Shanghai Tumor Research Institute,more local residents die of lung cancer in the city
than anything else.Following breast cancer,it has the second-highest incidence rate.
"An unhealthy lifestyle is a very important reason for lung cancer,"said Dr. He Yumin from Shanghai
Minshen Traditional Medicine Tumor Diagnosis and Treatment Centre.
He followed 2, 276 lung cancer patients for five years.Among them,1,483 were male.
Smoking causes 70 percent of cases among men while only 18 percent of female patients developed
cancer from smoking or inhaling second-hand smoke,according to the report.
However,more than 60 percent of women with the disease had long term,close contact with strong oil
fumes from cooking and complained about irritated eyes and throat.
About 32 percent women fried foods in boiling oil in unventilated kitchens and about 25 percent of
women's bedrooms were adjacent to the kitchen.
However,local women were surprised to learn cooking oil fumc、 could lead to cancer. Some claimed
they may change food preparation methods.
"Unless my family and I don't eat at home every day,I must stay in the kitchen to cook,"said Xu Li,
a 45-year-old local woman."I know the fumes are bad for the skin,but it is the first time that I heard it
result in lung cancer. I have already started frying less."
Doctors said women's lung cancer had few links to personal health and physical condition, but was closely
related to family cancer history,unhealthy dietary habits and weak immune systems.
Other experts agreed with him.
"Smoking is by far the biggest cause of lung cancer for men,"said Dr. Tan Binyong,honorary president
of the Respiratory Disease Institute at Fudan University's Medical College."It's true that second-hand
smoke and cooking fumes are the main causes among women."
His research also warned people not to stand near of stalls selling fried food due to the poor quality of
the oils used.
The chance of catching lung cancer is three times higher if one is exposed to the fume for a long time,
experts said. Which of the following has relatively little connection with women's lung cancer?
A.Family cancer history.
B.Unhealthy dietary habits.
C.Weak immune systems.
D.Personal health and physical condition.
