Invisible blood in urine may indicate bladder cancer — ScienceDaily

Scientists at the University of Exeter Medical School found that one in 60 people over the age of 60 who had invisible blood in their urine (identified by their GP testing their urine) transpired to have bladder cancer. The figure was around half those who had visible blood in their urine — the best known indicator of bladder cancer. However, it was still higher than figures for other potential symptoms of bladder cancer that warrant further investigation. Lead author Sarah Price, a PhD student at the University of Exeter Medical School, led the first robust study to investigate whether invisible blood in urine can indicate bladder cancer…

Some women still don’t underststand ‘overdiagnosis’ risk in breast screening

In a survey of around 2,200 women, Cancer Research UK scientists at University College London (UCL) found that 64 per cent felt they fully understood the information given about overdiagnosis — the chance that screening will pick up cancers that would never have gone on to cause any harm — by the National breast screening programme. Information about overdiagnosis has only been included in the NHS breast screening invitation leaflets since late 2013, meaning that overdiagnosis is likely to be a new concept for many people. …

Information about overdiagnosis has only been included in the NHS breast screening invitation leaflets since late 2013, meaning that overdiagnosis is likely to be a new concept for many people. But despite uncertainty over the information they were given, intentions to attend breast screening remained high, with only seven per cent of women saying they would be less likely to attend screening after receiving the overdiagnosis information…

Better classification to improve treatments for breast cancer — ScienceDaily

Cancer arises due to genetic changes which cause normal cells to develop into tumors. As we learn more about breast cancer, we are seeing that it is not one single disease — the mutations in the genes that cause different cancers are not alike, and this is why tumors respond differently to treatment and grow at different rates. Currently, there are two key markers that clinicians use to predict response to treatments. Spotting the trends in tumor genetics and creating a system to diagnose tumor types is a primary objective of cancer scientists. …

How premalignant cells can sense oncogenesis, halt growth

Since the 1980s, scientists have known that mutations in a human gene called RAS are capable of setting cells on a path to cancer. Today, a team at Cold Spring Harbor Laboratory (CSHL) publishes experiments showing how cells can respond to an activated RAS gene by entering a quiescent state, called senescence. CSHL Professor Nicholas Tonks and Benoit Boivin, now a University of Montreal Assistant Professor, co-led a team that traced the process in exquisite detail. …

Potential method to better control lung cancer using radiotherapy

Standard treatment for locally advanced non-small cell lung cancer is a combination of radiotherapy and chemotherapy. Traditionally this is planned in a one-size-fits-all manner but the radiation dose may not always be enough to stop tumor growth. The potential to increase the radiation dose to the cancerous tissue varies between patients and depends on the size and location of the tumor in relation to sensitive organs such as the spinal cord and lungs. …

New estrogen-based compound suppresses binge-like eating behavior in female mice

“Previous data has shown that women who have irregular menstrual cycles tend to be more likely to binge eat, suggesting that hormones in women play a significant role in the development or prevention of the behavior,” said Dr. Yong Xu, assistant professor of pediatrics and senior author of the paper. “Previous data has also shown that in humans, there is a strong association between estrogen and binge eating. …

Fighting prostate cancer with tomato-rich diet

With 35,000 new cases every year in the UK, and around 10,000 deaths, prostate cancer is the second most common cancer in men worldwide. Rates are higher in developed countries, which some experts believe is linked to a Westernised diet and lifestyle. To assess if following dietary and lifestyle recommendations reduces risk of prostate cancer, researchers at the Universities of Bristol, Cambridge and Oxford looked at the diets and lifestyle of 1,806 men aged between 50 and 69 with prostate cancer and compared with 12,005 cancer-free men. …
