Colon cancer patients who eat a diet high in red meat, fatty products, refined grains, and desserts ? a so-called ?Western diet? ? may be increasing their chance of disease relapse and early death, report researchers at Dana-Farber Cancer Institute.
Research investigators have identified molecular changes in multiple myeloma cells that activate an important biological pathway associated with cell growth and survival, thereby revealing potential new targets for drugs to treat this cancer.
The number of men in the United States with undiagnosed diabetes has declined sharply over the past 25 years, with Hispanics and African-Americans no longer more likely than whites to unknowingly have the disease, according to a RAND Corporation study issued today.
In some ways, certain tumors resemble bee colonies, says pathologist Tan Ince. Each cancer cell in the tumor plays a specific role, and just a fraction of the cells serve as ?queens,? possessing the unique ability to maintain themselves in an unspecialized state and seed new tumors. These cells can also divide and produce the ?worker? cells that form the bulk of the tumor.
Spine surgeon Paul Rubery, M.D., never imagined he would trade in his scalpel for Plaster of Paris, but that?s exactly what he?s planning to do in mid-August, when he learns a new, early treatment casting technique aimed at curing infants stricken with a devastating and aggressive form of scoliosis.
Researchers have found that metals present in tobacco smoke mimic the effects of estrogens and activate the body?s estrogen receptor, an action that may increase the risk of breast cancer. These metals are a new class of potent environmental estrogens called metalloestrogens, and smoking is a significant route of exposure.
When a woman receives a breast cancer diagnosis her entire life may change in the blink of an eye. But the nature of that change is governed by the smallest alterations that take place within the proteins of the tumor cells, determining what treatments she can pursue with a hope of cure and those to which her cancer is resistant.
Gender influences the prevalence and progression rate of many renal diseases, such as polycystic kidney disease (PKD). The physiology behind gender differences and renal disease is still uncertain, but the distinct characteristics of male and female kidney size, along with diet and the presence of hypertension, have all been thought to play a part.
The rich really are getting richer and the poor are getting poorer, a new University of Michigan study shows.
Contrary to expectations, diets high in the nutrient choline were associated with an increased risk of some colorectal polyps, which can?but do not always?lead to colorectal cancer, according to a study published online in the August 7 Journal of the National Cancer Institute.
