Periodontal Disease May Be Linked To Increased Risk Of Pancreatic Cancer

Those with high levels of antibodies against bacteria associated with gum disease could be more than twice as likely to develop pancreatic cancer as those with low antibody levels according to the results of a new study published online this month in the journal Gut.

While the study doesn’t directly implicate poor oral health and periodontal disease with pancreatic cancer it does raise the possibility that maintaining good oral hygiene could lower an individuals chances of developing pancreatic cancer.


Diesel Emissions And Lung Cancer Risk

A diesel trainIn June this year, the International Agency for Research on Cancer (IARC) reclassified diesel emissions from group 2A (probably carcinogenic to humans) to group 1 (carcinogenic to humans). This puts diesel emissions in the same category as other group 1 carcinogens such as arsenic, asbestos, benzene, ethanol, and formaldehyde. Diesel emissions are associated with an increased risk of lung cancer and possibly an increased risk of bladder cancer although the evidence for this is limited.

These findings may be of concern to some, particularly those who drive diesel vehicles or who are exposed to signficant amounts of diesel emissions in the workplace. Diesel based cars are increasingly in popularity around the world. In Europe for example, about half of new cars sold have diesel engines. In the USA, around 3% of new cars sold are diesel based however this figure is expected to double to 6% by 2015.


Infections Cause 16% Of Cancers Worldwide

Almost 1 in 6 cases of cancer is caused by an infectious agent according to a new study published online in The Lancet this month. The study also found that the burden of infection-related cancers was higher in the developing world, in women, and in younger individuals.

Researchers from the International Agency for Research on Cancer (IARC), Lyon, France, analysed country specific cancer incidence data, to determine the proportion of cancers in each country that were attributable to infections.


Meat And Cancer – Country Comparisons

A chunk of meatMost scientists agree that a high intake of meat, particularly red meat, increases an individuals risk of developing certain forms of cancer however there is uncertainty over the extent of the link between the two. Comparing cancer rates and meat consumption across different countries provides some interesting insight on the link between meat consumption and cancer. The table below shows the ten countries with the highest and lowest levels of meat consumption per capita.


Lung Cancer Rate In UK Women Continues To Rise Despite Falling Smoking Prevalence

The number of cases of lung cancer among women in the UK continues to rise steadily despite dramatic falls in smoking prevalence during the last half of the 20th century according to new data from Cancer Research UK.

In 2009, Cancer Research UK reports that 23,041 new lung cancer cases were diagnosed in men and 18,387 cases in women. This makes lung cancer the second most commonly diagnosed cancer in both men and women, behind prostate and breast cancer respectively.


Obesity Linked To Higher Risk Of Prostate Cancer Treatment Failure

Bathroom ScalesNew research, presented this month at the 2012 American Association for Cancer Research annual meeting, has found that overweight and obese men are significantly more likely to experience PSA failure following prostate cancer surgery. PSA failure is generally defined as a detectable PSA level following radical prostatectomy to remove the prostate tumour suggesting that the cancer has not been completely eliminated.


Gap In Mortality Rates Between Smokers And Non Smokers Continues To Widen

Several recent studies have looked at trends in the mortality differences between smokers and non-smokers. The studies have all produced remarkably similar conclusions – the excess mortality associated with cigarette smoking continues to increase resulting in a growing life expectancy difference between non-smokers and smokers. This is damning for the cigarette industry who have long claimed that increased usage of filtered cigarettes and low tar or “mild” formulations has resulted in a safer product. This simply doesn’t appear to be the case, and if anything, cigarette smokers are at a higher risk of dying from lung cancer, heart disease, and other smoking related illnesses than ever before.


HIV Increases Risk Of Lung Cancer By More Than 50%

HIV infected individuals are 70% more likely to develop lung cancer, even after adjustment for major lung cancer risk factors such as smoking, according to the results of a study published online in the journal AIDS last month.

Several studies had already found increased rates of lung cancer amongst HIV infected individuals however it had been thought much of the increase was the result of higher smoking rates rather than the disease itself. The prevalence of smoking in HIV infected individuals is around 65% in the USA – more than twice the national average.


45% Of Male Cancers, 40% Female Cancers Preventable According To Study

While we all know that a significant proportion of cancers are preventable, a recent British study has attempted to quantify the precise percentage of cancers that could be prevented through lifestyle and environmental changes. The authors found that a massive 45% of male cancers and 40% of female cancers could be prevented through simple behavioural changes.

The research, which was led by Professor Max Parkin of the Centre for Cancer Prevention at the Wolfson Institute of Preventive Medicine, involved the identification of 14 factors that are known to be related to cancer risk.


High Dose Vitamin E May Actually Increase Risk Of Prostate Cancer

High dose supplemental vitamin E does not decrease the risk of developing prostate cancer and may in-fact increase risk slightly according to the results of a study published in the October 12 issue of the Journal of the American Medical Association.

Researchers used data from The Selenium and Vitamin E Cancer Prevention Trial to determine whether supplementation of either vitamin E, selenium, or both in combination could reduce the risk of developing prostate cancer.


Egg Eaters More Likely To Die From Prostate Cancer According To Study

An eggMen who frequently consume eggs are much more likely to die from prostate cancer according to the results of a study published in the journal Cancer Prevention Research last month. The study also found suggestive evidence that consuming large amounts of poultry and processed red meat following prostate cancer diagnosis increased the risk of subsequently dying from the disease.


Waist Size Linked To Increased Risk Of Breast Cancer

A tape measureFor many years, obesity has been suspected of playing a role in breast cancer risk. Most studies find little association between obesity and breast cancer risk in pre-menopausal women but a significantly increased risk of breast cancer in post-menopausal women. Recent research suggests that measures of central obesity such as waist circumference and the waist-to-hip ratio may be more accurate predictors of breast cancer risk than BMI alone.


What Are A Smokers Chances Of Dying From Lung Cancer?

Many smokers want to know their probability of dying from lung cancer in a given time frame, however calculating precise risks can be difficult because there are a variety of factors that influence lung cancer probabilities.

The most important factors influencing lung cancer risk are age, number of years of smoking, average number of cigarettes smoked per day, number of years since smoking ceased (if the individual is a former smoker), and a history of asbestos exposure (working in a high risk occupation for at least 5 years).


Cancer More Likely In Tall People

A recent study published in The Lancet this month adds to a growing body of evidence that suggests tall people are more likely to develop cancer than their shorter counterparts.

The study, led by British researchers at the Cancer Epidemiology Unit, University of Oxford, involved almost 1.3 million women who were followed for an average of 9.4 years.


Preventing Colorectal Cancer Through Diet And Exercise

Colorectal cancer is an extremely common and often fatal form of cancer. In the United States, it is the fourth most common type of cancer and is second only to lung cancer in terms of mortality with almost 52,000 deaths in the USA alone last year. The lifetime risk of developing colorectal cancer for a 30 year old living in the United States today is 5.24%. Although great advances have been made in recent years in the early detection and treatment of colorectal cancer, the 5-year survival rate from diagnosis is only 65%, much lower than the survival rates for some other common types of cancer such as breast, skin, and prostate cancer.


Lack Of Sleep Increases Breast Cancer Risk By Inhibiting Melatonin Production

A recent Japanese study, published by the British Journal of Cancer in September this year, has found that women who get six or less hours sleep a night are much more likely to develop breast cancer than the rest of the population.

The study involved 23,995 Japanese women aged between 40 and 79 who were followed for an eight year period. Over the course of the study, 143 women developed breast cancer. The researchers found that women who slept for 6 or less hours a night were 62% more likely to develop breast cancer compared to women who slept for an average of 7 hours a night.


Dairy Products Linked To Increased Risk Of Prostate Cancer

CheeseA high intake of dairy products can increase the risk of prostate cancer by as much as 30% according to a study published in the American Journal of Clinical Nutrition in 2001.

The researchers, based at the Harvard Medical School in Boston, used data from the Physicians’ Health Study which involved more than 20,000 men from the United States who were followed from 1984 to 1995.


Diets High In Fat, Low In Fruit & Vegetables Linked To Bladder Cancer

A bowl of fruitA low intake of fruit and vegetables, and a high fat diet may be risk factors for bladder cancer according to the findings of a study published in the American Journal of Epidemiology in April 2000.

The study involved the analysis of 38 previous research studies on the impact of diet on bladder cancer. The researchers looked at six dietary variables: high meat intake, high fat intake, low vegetable consumption, low fruit consumption, low intake of retinol (vitamin A), and low intake of beta-carotene.
