Chronic exposure to ground level ozone, a powerful greenhouse gas and a widespread air pollutant in many major cities, is linked to premature death from cardiovascular disease, finds a new study. The analysis also found a strong link between nitrogen dioxide, a marker for traffic pollution, and increased risk of death from lung cancer.
In the battle against brain cancer, doctors now have a new weapon: an imaging technology that will make brain surgery dramatically more accurate by allowing surgeons to distinguish between brain tissue and tumors at a microscopic level.
A team of scientists have shown that a protein once thought to inhibit the growth of tumors is instead required for initial tumor growth. The findings could point to a new approach to cancer treatment. The focus of the study was angiomotin, a protein that coordinates cell migration, especially during the start of new blood vessel growth and proliferation of other cell types.
Here’s a sobering fact for millions of young women heading back to school: The more alcohol they drink before motherhood, the greater their risk of future breast cancer. That’s according to new research from Washington University School of Medicine in St. Louis that, for the first time, links increased breast cancer risk to drinking between early adolescence and first full-term pregnancy.
When a cancer cell sloughs off the edge of a tumor in the breast, it faces a tough road to survive. The cell must not only remain physically intact as it rushes through blood vessels, but it also must find a new organ to lodge itself in, take in enough nutrients and oxygen to stay alive, and begin dividing, all while escaping notice by the body’s immune system.
Cells in the body wear down over time and die. In many organs, like the small intestine, adult stem cells play a vital role in maintaining function by replacing old cells with new ones. Learning about the nature of tissue stem cells can help scientists understand exactly how our organs are built, and why some organs generate cancer frequently, but others only rarely.
Coffee consumption is associated with a lower risk of prostate cancer recurrence and progression, according to a new study by Fred Hutchinson Cancer Research Center scientists. They found that men who drank four or more cups of coffee per day experienced a 59 percent reduced risk of prostate cancer recurrence and/or progression as compared to those who drank only one or fewer cups per week.
A new study has revealed marked differences in the genomic terrain of the two most common types of cervical cancer, suggesting that patients might benefit from therapies geared to each type’s molecular idiosyncrasies. The study compares the spectrum of cancer-related gene mutations in the two main subtypes of cervical cancer – adenocarcinoma and squamous cell carcinoma.
A new study at Moffitt Cancer Center could offer hope to people with melanoma, the deadliest form of skin cancer. Researchers are investigating whether an injectable known as PV-10 can shrink tumors and reduce the spread of cancer. PV-10 is a solution developed from Rose Bengal, a water-soluble dye commonly used to stain damaged cells in the eye.
Breastfeeding for long periods protects kids from obesity and stuttering—while guarding their moms from breast cancer, recent studies claim. If proven true in follow-up work, these studies—added to an earlier finding that breast- feeding wards off Alzheimer’s—may have women around the world pitching their baby bottles and going au naturel on the subway.
A gene that helps control the ageing process by acting as a cell’s internal clock has been linked to cancer by a major new study. Scientists at The Institute of Cancer Research, London, found a genetic variant that influences the ageing process among four new variants they linked to myeloma – one of the most common types of blood cancer.
The biological information that makes us unique is encoded in our DNA. DNA damage is a natural biological occurrence that happens every time cells divide and multiply. External factors such as overexposure to sunlight can also damage DNA.
Celery, artichokes, and herbs, especially Mexican oregano, all contain apigenin and luteolin, flavonoids that kill human pancreatic cancer cells in the lab by inhibiting an important enzyme, according to two new University of Illinois studies.
Daily, some patients’ cancer care is being revolutionized by Next Generation Sequencing (NGS). Clinicians suddenly wielding the magical ability to scan patient tumors for thousands of mutations at a pop—instead of one or two—are finding many tumors’ underlying “biomarkers” are vastly different than thought.
Researchers have provided the first comprehensive compendium of mutational processes that drive tumor development. Together, these mutational processes explain most mutations found in 30 of the most common cancer types. This new understanding of cancer development could help to treat and prevent a wide-range of cancers.
Ottawa researchers have developed unique virus-derived particles that can kill human blood cancer cells in the laboratory and eradicate the disease in mice with few side effects. While Dr. Bell and his colleagues have been investigating replicating viruses for the treatment of solid cancers for many years, with very promising results, this is the first major success they have had treating blood cancer (leukemia).
It is possible to see how advanced a bowel cancer is by looking at its metabolic 'fingerprint', according to new research. Bowel cancer is the third most common type of cancer globally, with over one million new cases diagnosed every year. Accurately determining the stage that a tumor has reached is crucial for deciding which treatments to offer.
For the first time, scientists have directly observed events that lead to the formation of a chromosome abnormality that is often found in cancer cells. The abnormality, called a translocation, occurs when part of a chromosome breaks off and becomes attached to another chromosome.
Researchers trying to develop a diagnostic tool for ovarian cancer are hoping dogs' keen sense of smell will lead them down the right path. An early detection device that combines old-fashioned olfactory skills, chemical analysis and modern technology could lead to better survival rates for the disease.
Patients with advanced chronic lymphocytic leukemia (CLL) often receive donor transplants that effectively “reboot” their own immune defenses, which then attack and potentially cure the hard-to-treat disease. However, there is a high rate of relapse in these patients, and the transplanted immune cells may also harm normal tissues, causing graft-versus-host disease (GVHD).
Genomic sequencing experts and pharmacologists revealed a striking mutational signature of upper urinary tract cancers caused by aristolochic acid, a plant compound contained in herbal remedies used for thousands of years to treat a variety of ailments such as arthritis, gout and inflammation.
Scientists report that they observed a strong and selective immune response in chronic lymphocytic leukemia (CLL) patients who received, shortly after donor transplant, several doses of a “personalized” tumor vaccine, composed of their own inactivated leukemia cells combined with an immune stimulant.
Neurosurgeons from University of California, San Diego are among the first in the world to utilize real-time magnetic resonance imaging (MRI) guidance for delivery of gene therapy as a potential treatment for brain tumors. Using MRI navigational technology, neurosurgeons can inject a novel investigational gene therapy directly into a brain malignancy.
Cancer drugs known as ErbB inhibitors have shown great success in treating patients with various types of cancer, but due to ErbB drug resistance, many other patients do not respond or have tumors come back. A new study reveals that much of this resistance develops because a protein called AXL helps cancer cells to circumvent the drug's effects.
The painful, red skin that comes from too much time in the sun is caused by a molecule abundant in the skin's epidermis, a new study shows. Blocking this molecule, called TRPV4, greatly protects against the painful effects of sunburn. The research could yield a way to combat sunburn and possibly several other causes of pain.
