‘Invisible tattoos’ could improve body confidence after breast cancer radiotherapy — ScienceDaily

Research suggests that the permanent pin prick marks made on the skin of women having radiotherapy reminds them of their diagnosis for years to come, reducing body confidence and self-esteem. It’s also more difficult to spot these tattoos in dark-skinned women, potentially leading to inconsistencies in the area being treated. The NIHR-funded researchers, based at The Royal Marsden hospital in London, asked 42 breast cancer patients undergoing radiotherapy to rate how they felt about their body, before the treatment and one month later. Half the women were offered fluorescent tattoos, only visible under UV light, while the other half had conventional dark ink tattoos. …

Cancer cell fingerprints in blood may speed up childhood cancer diagnosis

The researchers, from the University of Cambridge and Addenbrooke’s Hospital in Cambridge, found unique molecular fingerprints for 11 types of children’s tumours, which could be used to develop blood tests to diagnose these cancers. This may eventually lead to a quicker, more accurate way to diagnose tumours, and could also reduce the need for children to undergo surgery to get a diagnosis one day. The research was funded by Sparks, the children’s medical research charity, and Cancer Research UK. Each year almost 1,600 children are diagnosed with cancer in the UK…

Ethnic minorities less aware of cancer symptoms, more likely to identify barriers to seeking medical help

Researchers looked at nearly 50,000 responses to the Cancer Research UK Cancer Awareness Measure from people across England. They found that ethnic minority groups were consistently less aware of cancer symptoms. People with a black ethnic background were half as likely as white people to recognise that unexplained bleeding could be a symptom of cancer; while South Asians were a quarter as likely as white people to recognise that an unexplained lump or swelling could be a cancer symptom…

Step towards blood test for many cancer types

This is the first time that cancer-specific blood markers have been comprehensively reviewed and identified for further clinical development. This study, by the UK Early Cancer Detection Consortium, funded by Cancer Research UK, has analysed 19,000 scientific papers and found more than 800 biomarkers. The aim of this research is to develop a screening test from a single blood sample for multiple cancer types. All cancers produce markers in the blood, so it could be feasible to develop a general screening test for many different forms of the disease. …

Proton therapy shown to be less costly than some alternative radiotherapy techniques for early stage breast cancer

In a cost analysis study based on typical patient characteristics, researchers used Medicare reimbursement codes to analyze allowable charges for eight different types of partial and whole breast irradiation therapies and treatment schedules available to early stage breast cancer patients. Taken together, these represent roughly 98% of the treatment options available to these patients. …

Proton therapy shown to be less costly than some alternative radiotherapy techniques for early stage breast cancer — ScienceDaily

In a cost analysis study based on typical patient characteristics, researchers used Medicare reimbursement codes to analyze allowable charges for eight different types of partial and whole breast irradiation therapies and treatment schedules available to early stage breast cancer patients. Taken together, these represent roughly 98% of the treatment options available to these patients. The cost of proton therapy when used for APBI, introduced to decrease overall treatment time and toxicity, was estimated at $13,833. Comparatively, WBI using IMRT (x-ray) therapy resulted in the highest Medicare charges at $19,599. …

First detailed picture of cancer-related cell enzyme in action on chromosome unit

Enzymes like PRC1 turn on or turn off the activity of genes in a cell by manipulating individual chromosome units called nucleosomes. “The nucleosome is a key target of the enzymes that conduct genetic processes critical for life,” said Song Tan, professor of biochemistry and molecular biology at Penn State University and the leader of the study’s research team…

Tomosynthesis improves cancer detection in women with dense breast tissue

The study found that adding tomosynthesis (3D mammography) to routine biennial digital mammography screening among U.S. women with dense breasts could improve health outcomes at a reasonable cost relative to digital mammography screening alone. This is the first comparative effectiveness study performed at the national level using an established model, and it could influence future screening recommendations for women with dense breast tissue who comprise nearly half of all women in the United States. “We felt that this analysis would help inform timely policy and practice decisions given both increased attention to screening for women with dense breasts and rapid adoption of tomosynthesis in routine practice,” said Christoph I. …

Chest radiation to treat childhood cancer increases patients’ risk of breast cancer — ScienceDaily

Wilms tumor is a rare childhood kidney cancer that can spread to the lungs. When this spread occurs, patients receive a relatively low dose of 12-14 Gray of radiation therapy to the entire chest. To see if such exposure to radiation affects patients’ risk of developing breast cancer, Norman Breslow, PhD, of the University of Washington and the Fred Hutchinson Cancer Research Center in Seattle, led a team that studied nearly 2500 young women who had been treated for Wilms tumor during childhood and who had survived until at least 15 years of age…
