(Press-News.org) Even the lowest possible dose of aspirin (75 mg) can ward off bowel cancer, if taken regularly, finds research published online in the journal Gut.
This protective effect is apparent after just one year and in the general population, not just those considered to be at risk of developing the disease, which is the second most common cause of cancer death in the world, killing almost half a million people every year.
Although previous research has shown that aspirin protects against bowel cancer, it is not known what the most effective dose is and how long it needs to be taken for.
The research team investigated just under 2,800 people with bowel cancer and just under 3,000 healthy people, matched for age, sex, and residential locality.
All participants completed food frequency and lifestyle questionnaires to assess their usual diet and lifestyle choices, which are known to influence bowel cancer risk.
NSAID (non-steroidal anti inflammatory drug) intake was categorised as taking more than four tablets a month of low dose aspirin (75 mg), other NSAIDs, or a mix.
The likelihood of surviving bowel cancer once diagnosed or developing the disease anew was then tracked over five years.
In all, 354 (15.5%) of those with bowel cancer were taking low dose aspirin compared with 526 (18%) of their healthy peers.
Taking any NSAID regularly, curbed the chances of developing bowel cancer compared with those who didn't take these painkillers.
This finding held true, irrespective of lifestyle choices, age, diet, weight, and level of deprivation
After a year, taking daily low dose aspirin was associated with a 22% reduced risk of developing bowel cancer, and the magnitude of the reduction in risk was cumulative, rising to 30% after five years.
Some 1,170 people died out of a total of 3,417 people diagnosed with bowel cancer (including those who were healthy at the start of the study) during the monitoring period. Most of these deaths (1,023) were attributable to the disease.
Information on NSAID intake was available for 676 of these 1,023 deaths, and it showed that taking NSAIDs of any kind did not influence the risk of death from any cause nor did it increase bowel cancer survival.
But, crucially, the findings show that high doses of aspirin, taken for a long time, are not needed to help ward off bowel cancer, say the authors.

A study published in the international scientific journal Addiction reveals that restrictions on pub closing times imposed in 2008 within the Australian city of Newcastle have reduced the assault rate by 37 per cent.
The study, conducted at the University of Newcastle, shows the number of assaults in the Central Business District (CBD) fell from 33 per month before the restrictions were put in place, to 22 afterwards.
The team of researchers, led by Associate Professor Kypros Kypri, compared the Newcastle CBD assault rates with those in the nearby suburb of Hamilton, ...
Policymakers should increase their sense of urgency to stop the global spread of chronic diseases such as heart disease, cancer and diabetes that threaten the health and economies of industrialized and developing nations alike, Emory University global health researchers say.
Writing in the current issue of The New England Journal of Medicine, authors K. M. Venkat Narayan, MD, Mohammed Ali, MBChB, MSc, and Jeffrey Koplan, MD, MPH, assert that the worldwide spread of chronic conditions, also known as noncommunicable diseases, offers a unique opportunity for low-, middle- ...
Rosemont, Ill. – Several health plans have introduced physician rating systems to offer consumers more information when choosing their doctors. However, a recent study presented in the September issue of the Journal of Bone and Joint Surgery (JBJS) reveals that physician-tiering guidelines and results are not consistent across insurance companies, do not fully define quality; and could confuse consumers.
Since affordable and more accessible health care is a critical national challenge, the use of rating systems will increase as one response to rising costs. Doctors ...
Simply getting older is not the cause of mild memory lapses often called senior moments, according to a new study by researchers at the Rush Alzheimer's Disease Center. The study, published in the September 15, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology, found that even the very early mild changes in memory that are much more common in old age than dementia are caused by the same brain lesions associated with Alzheimer's disease and other dementias.
"The very early mild cognitive changes once thought to be normal aging ...
In the Life After Cancer Epidemiology (LACE) study, 1,897 participants diagnosed with early-stage breast cancer between 1997 and 2000 and recruited on average 2 years post-breast cancer diagnosis were evaluated for the association between alcohol intake and breast cancer recurrence and death. The women, who were generally light drinkers, were followed for an average of 7.4 years. The study reported an increase in risk of breast cancer recurrence and breast cancer death, but no effect on total mortality, to be associated with consumption of 3 to 4 or more drinks per week ...

ANN ARBOR, Mich..---When men outnumber women, females marry younger and the age gap between spouses grows, a University of Michigan study shows.
"Women don't stay on the market long because men are more motivated to commit," said Daniel Kruger, research assistant professor in the U-M School of Public Health. "They want to secure ...
OAK RIDGE, Tenn., Sept. 15, 2010 -- New insight into the structure of switchgrass and poplars is fueling discussions that could result in more efficient methods to turn biomass into biofuel.
Researchers from the Department of Energy's Oak Ridge National Laboratory and Georgia Tech used small-angle neutron scattering to probe the structural impact of an acid pretreatment of lignocellulose from switchgrass. Pretreatment is an essential step to extract cellulose, which can through a series of enzymatic procedures be converted into sugars and then ethanol. The findings, published ...
Air Force Office of Scientific Research-sponsored researcher, Dr. Robert Wood of Harvard University is leading the way in what could become the next phase of high-performance micro air vehicles for the Air Force.
His basic research is on track to evolve into robotic, insect-scale devices for monitoring and exploration of hazardous environments, such as collapsed structures, caves and chemical spills.
"We are developing a suite of capabilities which we hope will lead to MAVs that exceed the capabilities of existing small aircraft. The level of autonomy and mobility ...
(PHILADELPHIA) A molecule known to be involved in progressive heart failure has now been shown to also lead to permanent damage after a heart attack, according to researchers at Thomas Jefferson University.
To prove this novel conclusion, the research team used gene therapy to inhibit the small protein, kinase known as G protein-coupled receptor kinase 2 (GRK2), and found heart muscles cells in mice were substantially protected against destruction that would otherwise occur after an induced myocardial infarction (MI), or heart attack.
Conversely, mice engineered to ...
Hurricane Julia intensified rapidly overnight and is now a Category 4 hurricane on the Saffir-Simpson Scale and NASA's Aqua, Terra and TRMM satellites captured clues as they passed over her from space.
The Tropical Rainfall Measuring Mission (TRMM) satellite passed over intensifying hurricane Julia during the afternoon of Sept. 14 and captured very heavy rain falling at 1807 UTC (2:07 p.m. EDT). That heavy rainfall was a clue that she would intensify overnight, and today, Sept. 15, she has become a Category Four hurricane on the Saffir-Simpson Scale.
TRMM's Precipitation ...
