The drug, which can be orally administered, targets a key protein that triggers the development of many types of cancer including lung, breast and skin cancers. The development of BP-1-102 was guided by the research teams computer based molecular analysis of the cancer causing Stat 3 protein.

Researchers found apigenin shrank a type of breast cancer tumor that is stimulated by progestin, a synthetic hormone given to women to ease symptoms related to menopause.

The findings show that the presence of fetal cells is a double-edged sword: Women with the lowest concentration of fetal cells were 70 percent less likely to have breast cancer, while women with the highest concentration of fetal cells had a four-fold increased risk for colon cancer when compared with healthy controls.

A new study found high levels of cancer-fighting TNF-related apoptosis inducing ligand (TRAIL) in human milk, which might be one source of breast milk's anticancer activity.

New research demonstrates that the protein Perp, associated with desmosomes (the glue that sticks cells together), is involved in suppressing breast cancer and provides a potential new target for future treatment. Fri, 20 Apr 2012 10:55:55 EDT http://www.sciencedaily.com/releases/2012/04/120420105543.htm http://www.sciencedaily.com/releases/2012/04/120419090715.htm New research findings show how it may be possible to render cancer tumors harmless without affecting the other cells and tissues in the body. The findings apply to cancers including breast, lung and bowel cancer. Many of the most common chemotherapy drugs used to treat cancer have serious side effects because they not only affect the cells in the cancer tumor, but also the cells in the rest of the body.

The five-year survival rate is between 25 and 50 percent. The reason for the poor prognosis is that IBC usually grows rapidly and often spreads quickly to other parts of the body. Researchers have developed a new cell and animal model that holds promise for providing a detailed understanding the disease and for developing effective interventions.

The study of women in China was presented by postdoctoral fellow Sarah J. Nechuta, Ph.D., M.P.H., at the American Association for Cancer Research Annual Meeting in Chicago, Ill.

The results indicate that inflammatory cells known as mast cells play a key role in this increase and that interfering with mast cells reduces the occurrence of bone and lung metastases.

Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy breast cells.

Cadmium occurs at low concentrations naturally, but scientists are concerned because contamination of farmland mainly due to atmospheric deposition and use of fertilizers leads to higher uptake in plants. Consuming whole grains and vegetables may counteract the effects.

The data demonstrate that by combining two drugs that had already been used on a patient in the past but had stopped working, they boost each other’s efficacy and at the same time manage to break down the patient’s resistance to each of them individually, presenting a third potential treatment option for clinically advanced metastatic tumors. While this may not initially appear to be an innovation, given that combined treatments are used in cancer as a matter of course, it actually represents a radical change in the use of the existing therapeutic weaponry, an extremely practical solution and a source of hope for many patients.

Now, scientists have shed new light on exactly how the activation of a pair of inflammatory signaling pathways leads to the transformation of normal breast cells to cancer cells.

New research has found that while TFF3 protein expression is higher in well-differentiated low grade tumors and therefore associated with features of a good prognosis, it has a more sinister role in breast cancer invasion and metastasis.

Researchers report for the first time that radiation treatment -- despite killing half of all tumor cells during every treatment -- transforms other cancer cells into treatment-resistant breast cancer stem cells. Researchers stressed that breast cancer patients should not be alarmed by the study findings and should continue to undergo radiation if recommended by their oncologists.

Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.

One recent article focuses on an imaging agent that targets estrogen receptors in estrogen receptor–positive breast cancer patients with formerly inconclusive assessments, and the second highlights a different imaging agent's ability to help predict the prognosis for patients undergoing chemotherapy for a very aggressive type of breast cancer.

Parabens are commonly used as preservatives in cosmetics, food products and pharmaceuticals. As the research shows that parabens are measurable in the tissue of women who do not use underarm cosmetics the parabens must enter the breast from other sources.

However, survivors continue to face health challenges after their treatments end. Previous research reports as many as 50 percent of breast cancer survivors are depressed. Now, researchers say a meditation technique can help breast cancer survivors improve their emotional and physical well-being.

In estrogen receptor-negative breast cancer, the production of this microRNA is often reduced and this is correlated with malignant behavior of tumor cells. The team has found out that tumors with low levels of miR-520 have a particularly strong tendency to metastasize.
