Lung cancer rates in younger white and Hispanic women surpass those of men - desktop air purifier

Reversing the historical trend, the incidence of lung cancer in young white and Hispanic women has exceeded that in men --
The researchers said Wednesday that the gender difference in smoking behavior could not fully explain the change.
Previous studies have pointed out that the incidence of lung cancer is changing, and the incidence of some women's groups is rising.
According to its authors, the new study, published in the New England Journal of Medicine, is the largest and most definitive study on the subject and combines smoking patterns and tumor features in the analysis.
The study, conducted by the American Cancer Association and the National Cancer Institute, did not explain why lung cancer
Incidence of cancer in white and Hispanic women born since the middle
1960 are higher than men.
But it also raises the possibility that some other scientists are pursuing, including the possibility of biology and genetics.
It points out, for example, that when people stop smoking, their risk of cancer falls every year.
However, compared with other types of lung cancer, the risk of adenocarcinoma, a common disease, decreased more slowly.
Women are more likely to develop adenocarcinoma than men.
Ahmedin Jemal, an epidemiology at the Cancer Association that led the study, said: "One hypothesis is that the reduction in lung cancer risk in women after quitting smoking may be slower than in men . ".
The researchers analyzed all cases of lung cancer in most areas of the United States from 1995 to 2014.
Overall, they found that the incidence of lung cancer in both men and women in the group had declined over the past 20 years, but the decline in men was greater.
Therefore, the historical pattern of high incidence of lung cancer in men has changed, and now the incidence of lung cancer in white and Hispanic women is higher.
(The proportion of black women in these age groups is still lower than that of black men.
) This finding confirms what many doctors have said: they see more women with lung cancer than in the past.
"Lung cancer doctors all have this experience and see more and more female patients and more patients who have never smoked," Marc Ladanyi said . " A lung cancer researcher and the director of molecular diagnostics at the Cancer Center in Sri Lanka, did not participate in the study.
Ladanyi led a 2012 study that showed that female smokers were more likely to have a specific gene mutation associated with adenocarcinoma than men.
In a study published on Wednesday, when all races and ages were combined, the incidence of lung cancer in men was still higher than in women.
Only when researchers study specific age and ethnic groups have new patterns emerged.
For example, while the prevalence of smoking in Hispanic women is much lower than in men, they have a higher incidence of lung cancer.

The Columbia Presbyterian University Medical Center suspects that some women have a "genetic tendency", which makes them more prone to lung cancer, especially when combined with certain environmental toxins such as second-hand smoke.
What is puzzling, he says, is that many of his patients do not smoke.
This is the case with the 35-year-old Kelly, who coughed three years ago.
She tried taking antibiotics, bought an air purifier and kicked her 75-
There is a golden retriever on her bed. After an X-
Ray and other tests showed a lump in her right lung and she had surgery in New YorkPresbyterian.
"It's a shock," she said, when pathology reports show cancer . ".
"I have never smoked, and I have never smoked in a smoker's environment, and I am only 32 years old.
"Because her malignant tumor was discovered early on, she did not have to undergo chemotherapy or radiotherapy and did not recur.
Lung cancer is the number one cancer killer in the United States and the world.
The American Cancer Society estimates that more than 234,000 people in the United States will be diagnosed with cancer this year, and about 154,000 will die from the disease.
Experts say about 85% of cases are caused by smoking.
