Women aged 50-69 years who attend mammography screening reduce their risk of dying from breast cancer by 40 percent compared to women who are not screened - according to a major international review of the latest evidence on breast cancer screening. Overall, women who are invited to attend mammography screening have a 23 percent risk reduction in breast cancer death (owing to some attending and some not), compared with women not invited by routine screening programs.

In the UK, this relative risk translates to around eight deaths prevented per 1,000 women regularly attending screening, and five deaths prevented per 1,000 women invited to screening.


Cancer has overtaken cardiovascular disease, which includes heart disease and stroke, as the UK's No 1 killer--but only among men, reveals research published online in the journal Heart.

Cardiovascular disease is still the most common cause of death among women, and kills more young women than breast cancer, the figures show.

The researchers used the latest nationally available data (2012-13) for each of the four UK countries and the Cardiovascular Disease Statistics 2014 report compiled for the British Heart Foundation (BHF) to quantify the prevalence of cardiovascular disease, and find out how it's treated, how much it costs, and how many deaths it causes.


Esophageal cancer rates in men have increased by 50 percent since the early 1980s, with new United Kingdom cases reaching almost 6,000, according to the latest figures which show that the number of men diagnosed with esophageal cancer has rapidly risen from around 2,700 cases three decades ago to 5,740 cases in 2012.

Given the changes in population size this equates to a 50 percent increase from 15 to 23 cases per 100,000 people. In women, the increase is much smaller with around 10 percent more now developing the disease compared to the 80s. Now 2,802 women are diagnosed with esophageal cancer.  Esophageal cancer rates in women for 2012 are 9 per 100,000. 

A new study found that esophageal cancer patients treated with proton therapy experienced significantly less toxic side effects than patients treated with older radiation therapies. 

The researchers looked at nearly 600 patients and compared two kinds of X-ray radiation with proton therapy, which targets tumors while minimizing harm to surrounding tissues.  found that proton therapy resulted in a significantly lower number of side effects, including nausea, blood abnormalities and loss of appetite. 


Prostate cancer is the second most common type of cancer in men and is predicted to result in an estimated 220,00 cases in the United States in 2015.


More than 500,000 people in the United States die each year of cancer-related causes and a new study has identified the mechanism behind one of the most common mutations that help cancer cells replicate limitlessly.

Approximately 85 percent of cancer cells obtain their limitless replicative potential through the reactivation of a specific protein called telomerase (TERT). Recent cancer research has shown that highly recurrent mutations in the promoter of the TERT gene are the most common genetic mutations in many cancers, including adult glioblastoma and hepatocellular carcinoma.


The United States remains mired in an economic downturn, with over 90 million unemployed and many of the employed making less than they made before 2009. The knock-on effects of the economic downturn have been explored in economy and psychology. Now researchers are examining the effects of unemployment on an even darker subject - cancer mortality.

One would think that dealing with unemployment was challenge enough. But according to the latest research published in ecancermedicalscience, rises in unemployment are associated with significant increases in prostate cancer mortality.


A recent study concluded that low-income and uninsured women in states that are not expanding their Affordable Care Act (ACA) Medicaid coverage are less likely to receive breast and cervical cancer screenings compared to states that are implementing expansions, even though such low income people are now given health care coverage under the ACA.


Men with naturally high levels of the female hormone estrogen have a greater risk of developing breast cancer, according to according to an epidemiology paper published in the Journal of Clinical Oncology.

This is the first time a link between estrogen levels in the blood and male breast cancer has been identified, despite its connection to breast, womb and ovarian cancers in women, according to study author Professor Tim Key, Cancer Research UK's hormone and nutrition expert at the University of Oxford. Men with the highest levels of estrogen were two and a half times more likely to develop breast cancer than men with the lowest levels of the hormone.


A research team writes in Cell Metabolism that they have uncovered a clue to how bacteria may promote some colon cancers.

The work used metabolomic technologies to find molecular evidence suggesting a vicious circle in which cancerous changes in colon cells promote the growth of bacterial conglomerations called biofilms, and biofilms in turn promote cancer development. 

On the whole, the findings suggest that removing bacterial biofilms could be a key strategy for preventing and treating colon cancers, which currently kill about 50,000 Americans per year. The study also revealed an apparent metabolic marker of biofilm-associated colon cancers.
