Smoking raises Odds for Breast Cancer in women at high risk

Researchers have analyzed how smoking, drinking and physical activity affected the risk of several common cancers in the 13,388 women at increased risk of breast cancer due to family history of breast cancer, age and other factors. Women participated in the U.S. National Surgical Adjuvant Breast and bowel (NSABP) Breast Cancer Prevention Trial project.

Those who have never smoked, women who smoke at least 35 years had 60% greater risk of invasive breast cancer and more than four times the risk of colon cancer, the researchers found.

Women who smoke during 15 to 35 years were 34 percent more likely to develop invasive breast cancer and 7 per cent more likely to develop a colon cancer than those who have never smoked.

Smokers to less than 15 years have had no increased risk of invasive breast cancer, according to the report.

To those who have never smoked, women who smoked a pack of cigarettes a day for more than 35 years were 30 times more likely to develop lung cancer, while the risk was 13 times higher for those who have smoked less than a pack a day more than 35 years.

Alcohol consumption was not associated with increased risk of cancer, but researchers have concluded that the low levels of physical activity were associated increased risk of 70% of endometrial cancer. It may be because women are more likely to be obese, a risk factor for endometrial cancer.

The study was posted online before its presentation on 6 June at the annual meeting of the American Society of Clinical Oncology, in Chicago.

"The NSABP study was the first large prospective study to examine the impact of smoking among women at high risk of breast cancer," said study author Stephanie Land, an associate professor of research in the Department of Biostatistics at University of Pittsburgh Graduate School of Public Health.

"Our results show an increase in still more risk that has been shown in previous studies, which suggests that women who are at risk of cancer of the breast of the family history or other factors.", smoking cigarettes is even more risky than other women "Land, said in a release ASCO."

"It sends a very important message for women with a family history of breast cancer on the long-term risks of smoking, and the importance of staying physically active." We note once more that the cessation is one of the most effective tools to reduce the risk of many cancers, ", she added."

Smoking may raise ratings for the return of Cancer of the Prostate

for men who have had their surgical resection due to prostate prostate cancer, smoking seems linked to an increase in blood levels of prostate specific antigen (PSA) - a measure of the risk of cancer recurrence.

Detects if a new study to be presented Monday at the annual meeting of the American Urological Association (AUA), Washington D.C.

The study involved 321 smokers and 309-smokers who underwent radical prostatectomy (removal of the prostate) from 1989 to 2005. Smokers have a higher volume and a higher volume of cancer high quality than non-smokers, according to researchers at Stanford University medical school.

Smokers has also tended to draw a steep rise in PSA blood levels, signaling a greater risk of "biochemical recurrence" cancer of the prostate. The PSA level increased approximately one per cent per pack-year smoked, the team discovered.

"These data suggest that the history of smoking could provide valuable information and should be included in prostate cancer risk assessment models," study presenter Dr. Joseph c. Presti, said in a press release AAU.

"The study also presents a strong message to men: smoking cessation now could affect your ability to survive to the prostate cancer later,"he added."".

Heavy smoking linked to cancer of advanced kidney

In a new study, a team of Duke University Medical Center examined the cases of 845 patients who had undergone surgery for cancer of the kidney - or kidney cancer - between 2000 and 2009. They found that current and former smokers were 1.5 to 1.6 times more likely to have advanced cancer than nonsmokers.

Heavy smoking (smoking during a longer period of time) and smoking more was associated with the advanced kidney cancer. The habit of kicking reduces the risk of advanced disease of 9% for all 10 years who was a former smoker without smoke, researchers have discovered.

The findings have provided for the presentation Sunday at a special press conference at the annual meeting of the American Urological Association, Washington D.C.

Another study scheduled for presentation at the same briefing found that the rate of bladder cancer were not with the United States smoking rates.

Researchers examined a national database and found that lung cancer rates declined along with the decrease of the per capita consumption of cigarettes between 1973 and 2007, but the same type of consistent decline was not seen in the rates of bladder cancer.

There may be a decrease in cancer of the bladder due to smoking, but this decrease may have compensated by other factors contributing to an increase in cancer of the bladder over the past decades, researchers at the State University of New York Upstate Medical University in Syracusesaid in an American Urological Association press release.

"These two studies pour new light on the role that smoking could have two important urological cancers," moderator of press conference, said Dr. Toby Kohler in the press release.

"For cancer of the kidney, it is true that renal tumours are detected more often these days when they are small." However, it seems that smoking give a much greater risk that the cancer may be more aggressive. Quit smoking appears to reduce the risk, "said Kohler.

"" For cancer of the bladder on the other hand, the decrease in smoking rates has not affected the impact to the same degree that she has lung cancer, which suggests that there may be other factors that are more important for the development of the disease ""He added.

Because these studies are presented at a medical meeting, the data and conclusions should be considered preliminary until published in a refereed journal.

New takes of ban indoor smoking China effect (AP)

BEIJING-

Smoking, which is linked to the death of at least 1 million people in China each year, is one of the greatest threats to health of the country is confronted, show statistics of the Government. 30 Per cent of adults in China smoke, about 300 million people - a number equal to the entire population of the United States.

The Ministry of health in late March out modified guidelines on the management of public places which now ban smoking in most places such as hotels and restaurants, while still excluding workplaces. The rules have been established for implementation on 1 May.

But the State media have questioned on the effectiveness of the ban, with the official Xinhua News Agency quoting experts saying that he is likely to be ignored by smokers and operators of public places because it fails to specify the penalties for offenders.

China has already missed a deadline of January 9, 2011, to prohibit smoking in indoor public places, according to a global anti-tobacco Treaty backed with WHO. Experts say huge revenues from the monopoly of tobacco belonging to the interference State tobacco control measures.

Dr. Yang Gonghuan, Director of the National Chinese tobacco control Office, said despite the problems with the new rules, she remained hopeful that they could raise tobacco control efforts. She said that his Office is not responsible for the implementation of rules.

"I also recognize that there are imperfections in the current guidelines of the Ministry of health, and that to accomplish, preparations were also inadequate," said Yang. "But I think that we should come together to help advance the implementation of the regulations."

The rules are part of the regulations of the Ministry of health on the management of health - in public places a set of rules which also covers the fields, including ventilation, use of disinfectants, air quality and the pest.

The application of these regulations is linked to a problem in a society where smoking is so well that nearly half of all smoke boxes and the cigarette in male doctors are commonly exchanged gifts. People commonly light in waiting rooms of hospitals, arcade video game and even on domestic flights, despite the 1991 regulations that prohibit smoking in workplaces.

The revised regulations call for non-smoking signs to be put up in public places and to require the owners or managers of sites considered to be public to allocate places staff quit, users.
