According to a large, long-term study, 40 percent of all colorectal cancers might be prevented if people underwent regular colonoscopy screening. The new research also supports existing guidelines that recommend that people with an average risk of colorectal cancer should have a colonoscopy every 10 years.
A research team has shown scientifically what many women report anecdotally: that the breast cancer drug tamoxifen is toxic to cells of the brain and central nervous system, producing mental fogginess similar to “chemo brain.” The researchers also report they’ve discovered an existing drug compound that appears to counteract or rescue brain cells from the adverse effects of the breast cancer drug.
Researchers have discovered a new mechanism involving p53, the famous tumor suppressor, to fight against aggressive cancers. This strategy works by sabotaging the ability of the cancer cells to hide from the immune system. The research opens a new avenue to improve targeted cancer therapy by harnessing the body’s own immune system to control and eliminate cancer cells.
Scientists have found a way to make dramatic improvements to the cancer cell-killing power of vinblastine, one of the most successful chemotherapy drugs of the past few decades. The team’s modified versions of vinblastine showed 10 to 200 times greater potency than the clinical drug.
Most cancer drugs try to treat the disease by killing fast-growing cells, but another approach called immunotherapy tries to stimulate a person’s own immune system to attack the cancer itself. In a new study, scientists have developed a strategy to slow tumor growth and prolong survival in mice with cancer by targeting and destroying a type of cell that dampens the body’s immune response to cancer.
The process of glycosylation, where sugar molecules are attached to proteins, has long been of interest to scientists, particularly because certain sugar molecules are present in very high numbers in cancer cells. It now turns out that these sugar molecules are not only present, but actually aid the growth of the malignant cells.
The level of expression of three genes associated with aging can be used to predict whether seemingly low-risk prostate cancer will remain slow-growing, according to researchers. Using this biomarker could help physicians better determine which men with early prostate cancer should be spared the risks of prostate removal or other invasive treatment.
Terahertz radiation, the technology that peeks underneath clothing at airport security screening check points, has great potential for looking underneath human skin to diagnose cancer at its earliest and most treatable stages, according to new research.
Delivery of cancer care in the U.S. is facing a crisis stemming from a combination of factors—a growing demand for such care, a shrinking oncology work force, rising costs of cancer care, and the complexity of the disease and its treatment, says a new report from the Institute of Medicine.
For the first time, a genetic link specific to risk of childhood leukemia has been identified, according to a team of researchers from Memorial Sloan-Kettering Cancer Center, St. Jude Children’s Research Hospital, University of Washington, and other institutions.
Scientists have found a gene in mice that could protect against ovarian cancer and, if faulty, may increase the chance of developing the disease, according to research. This gene, known as Helq, helps repair any damage to DNA that happens when it is copied as cells multiply.
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.
