Blood is the juice of life, as while circulating through the body it delivers vital substances such as oxygen and nutrients to cells and tissues. Chemotherapy, radiotherapy and blood loss in general impoverish the system. A special kind of cells in the bone marrow, called hematopoietic stem cells (HSCs) is able to replenish the impoverished system by giving rise not only to red blood cells, but…
Making tumour cells glow: Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in "Communication Physics".
Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth and spread of tumors. Now researchers from The Scripps Research Institute are reporting an innovative…
Idiopathic pulmonary fibrosis (IPF) is one of the most challenging and frustrating diseases that pulmonologists face. And despite affecting 1 out of 200 adults over the age of 65 in the United States, general awareness of IPF is low. “There’s a tremendous disconnect between the human impact of this disease and its recognition by the public. Few people have ever heard of it,” says Marc…
Weak, easily broken bones are an epidemic in the United States. They’re often tied to osteoporosis, a disease that causes bones to degenerate over time. This makes them less flexible, more brittle, and easier to break. According to the International Osteoporosis Foundation, more than 44 million Americans aged 50 and older either have or face the threat of developing osteoporosis due to low bone…

Hoseon Lee, an assistant professor of electrical engineering in the Southern Polytechnic College of Engineering and Engineering…
Cancer is a genetic disease caused by abnormal changes over time to genes that control cell function, typically starting in a single cell (an acquired mutation) and often not linked to an inherited genetic mutation. In other words, most cancers happen by chance. Only about 5 to 10 percent of cancers are due to an inherited genetic mutation, says Monique Lubaton, MGC, CGC, cancer genetic counselor…
Humans and other mammals have a lot in common. Depending on race, 80 to 98% of mammalian genetic makeup is identical to the human one. Nevertheless, the variety of life expectancy among mammals is huge; and so far, it was unclear, which impact the genetic makeup has on a species’ life span. In rodents, differences in life expectancy and morbidity during aging are particularly high: Despite…
Belly fat affects the odds of women surviving kidney cancer but not men, according to a new study by researchers at Washington University School of Medicine in St. Louis. Half of female kidney cancer patients with substantial abdominal fat at the time of diagnosis died within 3 1/2 years, while more than half of women with little belly fat were still alive 10 years later, the researchers found.…
A Case Western Reserve University School of Medicine researcher has compiled evidence from more than 100 publications to show how obesity increases risk of 13 different cancers in young adults.

The FDA has been closely tracking the relationship between breast implants and a rare type of non-Hodgkin's lymphoma since we first identified this possible association. We’ve been working to gather additional information to better characterize and quantify the risk so that patients and providers can have more informed discussions about breast implants,” said Binita Ashar, M.D., director of…
Feline AIDS is caused by the Feline Immunodeficiency Virus (FIV), which is very similar to the HIV-1 virus that affects millions of humans. While FIV does not infect humans, many groups research the virus to benefit cats, and perhaps more importantly, because of its many parallels with the AIDS virus. Despite the use of dedicated drugs, HIV-1 manages to thrive and multiply within the cell and…
Throughout life, DNA is constantly being damaged by environmental and intrinsic factors and must be promptly repaired to prevent mutations, genomic instability, and cancer. Different types of damages are repaired by numerous proteins organized into damage-specific pathways. The proteins from different pathways must be spatially and temporally coordinated in order to efficiently repair complex DNA…

Now, however, researchers at Stanford University and the Technical University of Denmark have come up with a new method that will enable doctors to make a more precise diagnosis, prognosis and…
Engineering researchers at the University of Arkansas have moved closer to developing an alternative method of detecting and possibly treating breast cancer. Terahertz images of breast tumors taken from mice accurately detected cancerous tissue with a high level of specificity.
Recognising malignant tissue remains a tricky task. While today, most patients undergo a biopsy, an invasive procedure where tissue is sampled, stained and assessed, researchers are exploring the potential of optical biopsy, the visual assessment of suspect tissue. The interest in optical biopsy ‘is indeed enormous,’ confirms Dr Thomas Bocklitz, physicist at Friedrich-Schiller University in…
Immunotherapy is taking center stage in imaging, but patient follow-up with CT is no cookie and may fall short in the peripheral limbs, brain and bone marrow. MRI offers specific benefits in these situations, and, combined with PET, it may bring even more results. Research must be carried out on quantitative techniques and tracers developed to fully exploit that potential, Prof. Dow-Mu Koh…
With immunotherapy, bigger lesions may be spotted on CT, but it doesn’t necessarily mean that the disease is progressing. As treatment works, it can cause what has become known as pseudo disease progression; and this is just one of the many revolutions immunotherapy is triggering in oncology imaging, Professor Clarisse Dromain (Lausanne/CH) explained as she opened the session dedicated to this…
Some time in the distant future artificial intelligence (AI) systems may displace radiologists and many other medical specialists. However, in a far more realistic future AI tools will assist radiologists by performing very complex functions with medical imaging data that are impossible or unfeasible today, according to a presentation at the RSNA/AAPM Symposium during the Radiological Society of…
Conventional chemotherapy in oncology is increasingly yielding to new procedures such as targeted therapy and immunotherapy. This results in changes for radiologists because new procedures require familiarisation with certain imaging to ensure that the treatment process is interpreted correctly.
Testing cancer drugs on miniature replicas of a patient’s tumour could help doctors tell in advance which treatments will work, a major new study reports.

Donating blood is a tangible way to help people who are struggling with serious health conditions, yet many people may not think about it or make time for it. In January – which the American Red Cross has dubbed National Blood Donor Month – blood bank supplies are typically among the lowest of the year, as many people have been traveling or busy with the holidays. Inclement weather can also…
The most common type of tumor found in the kidney is generally quite small (less than 1.5 in). These tumors are usually found by accident when CAT scans are performed for other reasons and the serendipitous finding poses a problem for doctors. Are these tumors malignant and do they need to be surgically removed because they may threaten the patient’s life? Or are they benign and can be left…
Mount Sinai researchers have discovered that normal immune cells called macrophages, which reside in healthy breast tissue surrounding milk ducts, play a major role in helping early breast cancer cells leave the breast for other parts of the body, potentially creating metastasis before a tumor has even developed, according to a study published in Nature Communications. The macrophages play a role…
Through gene therapy, researchers engineered blood-forming stem cells (hematopoietic stem/progenitor cells, or HSPCs) to carry chimeric antigen receptor (CAR) genes to make cells that can detect and destroy HIV-infected cells. These engineered cells not only destroyed the infected cells, they persisted for more than two years, suggesting the potential to create long-term immunity from the virus…
A new marker that could be used to diagnose fatal breast cancer up to one year ahead of current methods has been identified in a study led by UCL.

Lars Schimmöller MD, associate professor of radiology at Düsseldorf University Hospital, tackled current diagnosis of prostate cancer (PCa) and addressed tumour detection, staging, active surveillance and recurrence during the Medica Academy session on Imaging Update. He also highlighted how MRI helps improve biopsies and avoid unnecessary surgery in PCa.
For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…
Using light-emitting nanoparticles, Rutgers University-New Brunswick scientists have invented a highly effective method to detect tiny tumors and track their spread, potentially leading to earlier cancer detection and more precise treatment. The technology could improve patient cure rates and survival times. “We’ve always had this dream that we can track the progression of cancer in real…
When immune cells invade the tumor, this is usually considered a good sign because the body's own immune system appears to be responding to the cancer. In the case of certain types of breast cancer immune cells, namely so-called tumor-infiltrating lymphocytes (TILs), these can determine survival rates and predict the usefulness of chemotherapy. This was shown by the largest meta study on TIL…
Genentech researchers have identified an enzyme that shifts pancreatic cancer cells to a more aggressive, drug-resistant state by epigenetically modifying the cells’ chromatin.

Johns Hopkins Kimmel Cancer Center researchers demonstrated that mice with ovarian cancer that received drugs to reactivate dormant genes along with other drugs that activate the immune system had a greater reduction of tumor burden and significantly longer survival than those that received any of the drugs alone. The study already spurred a clinical trial in ovarian cancer patients. The…
Determining where breast cancer ends and healthy tissue begins is a critical part of breast cancer surgery. Surgeons are used to working closely during surgery with anatomic pathologists who generate pathology reports that specify the surgical or tumor margin, an area of healthy tissue surrounding a tumor that also must be excised to ensure none of the tumor is left behind. This helps prevent the…
UV radiation has been known for a long time to be a risk factor for the development of skin cancer. Simultaneous infection with human papillomaviruses (HPV) has also been suspected to promote skin cancer, particularly in organ transplant recipients. Scientists from the German Cancer Research Center (DKFZ) have now been able to show for the first time in a natural system that papillomaviruses…
Cancer therapies including radiation and chemotherapy seek to treat the disease by killing tumor cells.

It had already been known that the enzyme known as phosphatidic acid phosphatase plays a crucial role in regulating the amount of fat in the human body. Controlling it is therefore of interest in the fight against obesity. But scientists at Rutgers University-New Brunswick have now found that getting rid of the enzyme entirely can increase the risk of cancer, inflammation and other ills.
A team of scientists and engineers at The University of Texas at Austin has invented a powerful tool that rapidly and accurately identifies cancerous tissue during surgery, delivering results in about 10 seconds—more than 150 times as fast as existing technology.
As cancer grows, it evolves. Individual cells become more aggressive and break away to flow through the body and spread to distant areas. What if there were a way to find those early aggressors? How are they different from the rest of the cells? And more importantly: Is there a way to stop them before they spread?
The mouse is the most widely used model organism to understand human genetics, biology, and diseases in the research setting. But new research findings have revealed important divergences between the species which scientists will need to understand better through further investigation.

Researchers exploring combination therapies have recently discovered improved survival rates by up to one year when patients treated with a newly formulated chemotherapy regimen are also given radiation therapy.
Every cancer is different and every patient is different. This insight gained in personalised medicine prompted oncology researchers to focus more on the individual patient’s immune system. It is particularly the immune system’s ability to destroy cancer cells that raised hope.
A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized cancer cells in the blood stream and then killing these cells, according to a new research study.
In a bid to detect cancers early and in a noninvasive way, scientists at the Johns Hopkins Kimmel Cancer Center report they have developed a test that spots tiny amounts of cancer-specific DNA in blood.
There are various concepts about how blood cells develop. However, they are based almost exclusively on experiments that solely reflect snapshots. In a publication in Nature, scientists from the German Cancer Research Center in Heidelberg now present a novel technique that captures the process in a dynamic way.
Headlines, of late, have touted the successes of targeted gene-based cancer therapies, such as immunotherapies, but, unfortunately, also their failures.
Scientists from the University of Würzburg have synthesized a complex sugar molecule which specifically binds to the tumor protein Galectin-1. This could help to recognize tumors at an early stage and to combat them in a targeted manner.
A protein found in the edible mushroom known as "shaggy ink cap" might be able to kill a type of leukemia cell, new research suggests.
Johns Hopkins Kimmel Cancer Center scientists report they have discovered a biochemical process that gives prostate cancer cells the almost unnatural ability to change their shape, squeeze into other organs and take root in other parts of the body.
New findings from a scientific collaboration between the German Cancer Research Centre (DKFZ), the National Centre for Tumour Diseases (NCT) Heidelberg and the Thoraxklinik Heidelberg suggest liquid biopsy as a promising tool to monitor lung cancer patient tumours early. Scientists associated liquid biopsy readouts with clinical data and could track tumour responses to cancer drugs in real-time.
Lung cancer is the cancer that causes the highest mortality worldwide, claiming an estimated 1.7 million patients annually, with 270,000 of those deaths in Europe.
Findings suggest that modifying the cell replication cycle could make combined therapies more successful.
A pioneering diagnostic device identifies more abnormal cells on the cervix than standard colposcopy, according to data published in two European clinical papers.
An international research team led by Université de Montréal medical professor Christopher Rudd, director of research in immunology and cell therapy at Maisonneuve-Rosemont Hospital Research Centre, has identified a key new mechanism that regulates the ability of T-cells of the immune system to react against foreign antigens and cancer.
Cancer researchers in the UK may have stumbled across a solution to reverse antibiotic drug resistance and stop infections like MRSA. Experts warn we are decades behind in the race against superbugs having already exploited naturally occurring antibiotics, with the creation of new ones requiring time, money and ingenuity. But a team of scientists at the University of Salford say they may have…
Pancreatic cancer is one of the most deadly types of malignancies, with a 5-year survival rate after late diagnosis of only about 5%. The majority of patients—about 80%—receive their diagnosis too late for surgery. The disease spreads quickly and resists chemotherapy. In short, there is an urgent need for diagnostic tools to identify this cancer in its earliest stages.
The U.S. Food and Drug Administration has cleared the expanded use of a cooling cap, DigniCap Cooling System, to reduce hair loss (alopecia) during chemotherapy. This is the first cooling cap cleared by the agency for use in cancer patients with solid tumors.
Canadian researchers have invented an intraoperative probe that reliably detects multiple types of tumour cells.
A Fred Hutchinson Cancer Research Center study, led by epidemiologist Dr. Parveen Bhatti, found that night shift work is associated with reduced ability to repair DNA lesions. Over time, DNA damage that is not repaired will cause mutations that can lead to cancer.
Led by six globally-recognised experts in cancer care, the organisation known as CHILL, Cancer-related Hair Loss, International Leadership and Linkage, announced today an initiative to collect and track evidence-based patient information and clinical guidance. Data will be used to establish clinical best practices to ensure maximum effectiveness of scalp cooling to minimise chemotherapy-induced…
Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily. The study, conducted in both human and mouse cells, shows that cancer genomes lose copies of repetitive sequences known as ribosomal DNA. While downsizing might enable these cells to replicate faster, it also seems to render them less able to…
Scientists from St. Jude Children’s Research Hospital and Fred Hutchinson Cancer Research Center have developed an algorithm that functions like a Rosetta Stone to help decipher how the immune system recognizes and binds antigens. The research should aid development of more personalized cancer immunotherapy and advance diagnosis and treatment of infectious diseases.
Scientists from the German Cancer Research Center (DKFZ), in collaboration with colleagues from Heidelberg University Hospital, have been able to visualize brain cancer using a novel MRI method. They use a simple sugar solution instead of conventional contrast agents, which can have side effects in the body.
There hasn't been a gold standard for how orthopedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone regeneration it could become the method surgeons prefer.
Scientists on the Florida campus of The Scripps Research Institute (TSRI) have improved a state-of-the-art gene-editing technology to advance the system’s ability to target, cut and paste genes within human and animal cells—and broadening the ways the CRISPR-Cpf1 editing system may be used to study and fight human diseases.
A team of researchers has pinpointed a sugar modification in cells that spurs the spread of skin cancer. Its findings spotlight a target in the battle against melanoma.
Scientists have discovered that dying tumor cells release small pieces of their DNA into the bloodstream. These pieces are called circulating tumor DNA (ctDNA) or circulating cell-free DNA (ccfDNA).
According to Darwin, humans will one day become extinct. Some don’t think we need to accept this fate because gene editing may allow us to use our brains to take over the evolutionary story.
Drugs that are used in cancer therapy to erase epigenetic alterations in cancer cells simultaneously promote the production of countless mysterious gene transcripts, scientists from the German Cancer Research Center (DKFZ) now report in Nature Genetics. The substances activate hidden regulatory elements in DNA. The unusual gene activity has the potential to stimulate the immune system – a…
The cancer risk for a human mission to Mars has effectively doubled following a UNLV study predicting a dramatic increase in the disease for astronauts traveling to the red planet or on long-term missions outside the protection of Earth’s magnetic field.
Current view is that cancer development is initiated from cells that acquire initial DNA mutations. These in turn provoke additional defects, and ultimately the affected cells begin to proliferate in an uncontrolled manner to develop primary tumors. These can later spread and create metastases, or secondary tumors, in other parts of the body. However, according to a study by researchers at the…
An experimental treatment in mice allows the reprogramming of blood cells in order to promote the healing process of cutaneous wounds. This approach could prove to be beneficial in healing challenging wounds in diabetics and major-burn victims.
All cancer tumors have one thing in common – they must feed themselves to grow and spread, a difficult feat since they are usually in a tumor microenvironment with limited nutrients and oxygen. A study at The University of Texas MD Anderson Cancer Center has revealed new details about how an enzyme called acetyl-CoA synthetase 2 (ACSS2) allows brain tumors to grow despite their harsh…
