(HealthDay News) -- While no one should smoke, it may be even more important for people of certain races to avoid tobacco if they want to prevent lung cancer.
New research suggests that blacks and native Hawaiians who smoke between 10 and 20 cigarettes a day have a 30 percent to 40 percent higher risk of lung cancer than whites do. Latino and Japanese-American smokers had the lowest risk of lung cancer, about 20 percent less than whites and 60 percent less than blacks.
"Lung cancer incidence was higher among African-Americans and Hawaiians," said study author Christopher Haiman, an assistant professor in the department of preventive medicine at the University of Southern California Keck School of Medicine, in Los Angeles.
"But when you're talking about smoking, the message doesn't change; it stays the same. Elimination of smoking will reduce lung cancer incidence," said Haiman, and that's true no matter what your race. Read more...

Lung Cancer's Hidden Victims: Those Who Never Smoked
(HealthDay News) -- Opera legend Beverly Sills never smoked. Neither did actress and health advocate Dana Reeve, wife of the late actor Christopher Reeve.
And yet in 2007 and 2006, respectively, both joined the ranks of about 32,000 Americans each year who never touch a cigarette but die of lung cancer anyway.
In fact, experts say, one in every five cases of the leading cancer killer occurs in nonsmokers. The annual death toll among this group now approaches that of breast cancer (about 40,000 per year) and is roughly equal to that of prostate cancer (32,000). Many never-smoking women may also be unaware that they are more than twice as likely to die of lung cancer as they are of ovarian cancer (14,000 deaths per year).
Numbers like those have experts calling for a shift in the public's thinking on lung cancer, away from its label of "the smoker's disease."
"We say, 'If you have a lung, you can get lung cancer,'" said Linda Wenger, executive director of Uniting Against Lung Cancer (UALC), a nonprofit advocacy group aimed at reaching a better understanding of lung cancer. The group was founded after the death in 2001 of Joan Scarangello, an ABC and NBC journalist and lifelong nonsmoker who fell victim at age 47 to lung cancer. Read more...

Severe Swine Flu Could Lead to Blood Clots in Lungs: Study
(HealthDay News) -- People who are severely ill with the H1N1 swine flu run the risk of blood clots in the lungs, University of Michigan researchers say.
And because standard chest X-rays may not be able to spot the potentially fatal condition, more sophisticated CT scans may be needed to identify the risk, the researchers said.
Technically called a pulmonary embolism, the condition occurs when one or more arteries in the lungs become blocked. Aggressive use of blood-thinning drugs can reduce the risk of death, the researchers said.
"The high incidence of pulmonary embolism is important. Radiologists have to be aware to look closely for the risks of pulmonary embolism in severely sick patients," study lead author Dr. Prachi P. Agarwal, assistant professor of radiology at the University of Michigan Medical School, said in a university news release.
"With the upcoming annual influenza season in the United States, knowledge of the radiologic features of H1N1 is important, as well as the virus's potential complications. The majority of patients with H1N1 that undergo chest X-rays have normal radiographs. CT scans proved valuable in identifying those patients at risk of developing more serious complications as a possible result of the H1N1 virus," he added. Read more...

Stomach Cancer Tumors Have Genetic Differences: Researchers
(HealthDay News) -- Stomach cancer tumors have genetic differences, which determine how they respond to treatment, researchers have found.
In identifying two distinct versions of the disease, scientists found that a certain regimen of chemotherapy is more effective on one tumor type, while another drug works best on the other. The study authors said their findings would help doctors more effectively treat gastric cancer patients.
"Our study is the first to show that a proposed molecular classification of gastric cancer can identify genomic subtypes that respond differently to therapies, which is crucial in efforts to customize treatments for patients," study senior author Dr. Patrick Tan, associate professor in the Cancer and Stem Cell Biology Program at the Duke-National University of Singapore (NUS) Graduate Medical School, said in a university news release.
A microscopic pathology test developed in the 1960s, known as the Lauren classification, is a general description (either intestinal or diffuse) of how well the tumor cells clump together. The Singapore-based team at the Duke-NUS Graduate Medical School, however, was able to distinguish gastric cancer tumors where the Lauren test could not. Read more...

Selenium supplementation associated with reduced colorectal
The April 2006 issue of the International Journal of Cancer published the findings of researchers from Roswell Park Cancer Institute in Buffalo, New York that supplementing with selenium significantly reduced the risk of colorectal adenomas (polyps) among smokers or those whose levels of the mineral were low. Polyps can be a precursor to colorectal cancer (CRC).
The study population consisted of participants in the Nutritional Prevention of Cancer trial follow up who were randomized to receive a 200 microgram per day selenium supplement or a placebo for an average of 7.9 years. Plasma selenium levels, body mass index and smoking status were ascertained upon enrollment. Five hundred ninety-eight subjects received one or more sigmoidoscopic or colonoscopic examinations during the follow up period. There were 99 adenomas found during the initial examinations, which were classified as prevalent, and 61 identified at subsequent examinations, classified as incident. Read more...
