Elastrography, may Call the Shots During Initial Stage of Breast Screening

... be capable of distinguishing between harmless and malignant lumps in women’s breasts. This method of screening holds promise in the better utilization of breast biopsies, currently in use to detect the presence of breast cancer. Biopsies are rather costly and cumbersome; additionally the results may take da...

Molecular ‘Marker’ on Stem Cells Aids Research, Perhaps Therapis

...ells, as well as on embryonic carcinoma cells, the malignant counterparts of embryonic stem cells. Dr. Perlingeiro’s ongoing studies also suggest that the SSEA-4 molecule might be present in other tissues, leading to the intriguing possibility that the SSEA-4 molecule could be a marker for “stemness,” she sa...

Lenalidomide Gives New Hope To Chronic Lymphocytic Leukemia Patients

...ctivity of this agent has been reported in various malignant disorders, including multiple myeloma and myelodysplastic syndrome. In this phase II study – the first to report clinical activity of lenalidomide in patients with CLL – 45 patients with immunophenotypically diagnosed B-CLL were treated with a dai...

Sweat It Out- Prevent Colon Cancer

... cut the risk of colon tumors. Colon cancer is a malignant (cancerous) tumor arising from the inner wall of the large intestine. Although the exact causes of colon cancer are not known, it appears that both hereditary and environmental factors, like what we eat, play a role in its development. The early ...

Genes That Allow Brain Cancer-Causing Stem Cells to Resist Treatment Identified

...that appear to be the source of cells comprising a malignant brain tumor. Theoretically, if these mother cells can be destroyed, the tumor will not be able to sustain itself. On the other hand, if these cells are not removed or destroyed, the tumor will continue to return despite the use of current cancer-kill...

Researchers Find Stem-cell Therapy Effective in Targeting Metastatic Cancer

... that the technique could also be applied to other malignant solid tumors, including colon, brain, prostate and breast cancer, and are planning future preclinical trials using those tumors as well. Source-Eurekalert...

Risk Of Soft Tissue Sarcomas In Hereditary Retinoblastoma Survivors

...iagnosed sarcomas were fibrosarcoma (13 patients), malignant fibrous histiocytoma (12), rhabdomyosarcoma (8), and liposarcoma (3). The authors calculated that there was a 184-fold increase in soft-tissue sarcomas among hereditary retinoblastoma survivors compared with the general population and a 390-fold incr...

European Scientists Develop Novel Therapy for Cancer

...n, called CD40, can also induce the destruction of malignant cells by the body's own defenses. The scientists who participate in the program aim to combine CD40 triggering with chemotherapy or with innovative drugs that will cut-off signals necessary for the survival of cancer cells. This strategy is expected ...

A New Strategy to Control Breast Cancer

... inhibition of EGFR signaling and the reversion of malignant characteristics in tumor cells. It is the first reported use of protease inhibitors to stop breast cancer cell proliferation and restore the normal breast tissue structure. Tumor cells, says Bissell, exist in the same microenvironment as healthy c...

One-time Melanoma Screening Appears to Be Cost-effective for Elderly People

...of the general U.S. population at age 50 years for malignant melanoma is very cost-effective and that screening every two years of siblings of patients with melanoma may also be cost-effective, depending on disease progression rates,' according to the authors.

Scientists Map Key Landmarks in Human Genome

...activity) within seven human cell lines, including malignant melanoma. Nucleosomes are spherical packing units for DNA. They consist of a length of DNA wrapped around a core, like ribbon around a spool that is made up of proteins called histones, and the nucleosomes are located along the chromosomes like bea...

Dog Owners Definitely Healthier

...ack. Dogs are also shown to be able to sniff out malignant melanomas, as well as low sugar levels in their owners. They can also act as warning systems for epilepsy. Other studies have shown that the presence of dogs help chronically ill children cope better with painful medical procedures and can even he...

New Test Predicts CLL’s Sensitivity to Experimental Drug

...developed a test that is first to identify - which malignant blood cells are highly vulnerable to a promising// type of experimental drugs that unleash pent-up "cell suicide" factors to destroy the cancer. The researchers demonstrated that chronic lymphocytic leukemia, CLL, which is diagnosed in 10,000 Ameri...

Cancer Scientists' Gene Research Offers New Treatment Hope

...ody's immune system. In experiments on mice with malignant brain cancer all the tumours decomposed completely because they were no longer being protected by the silenced gene - known as TGF-beta. "We saw the tumours grow, then we saw them regress. I've been working on this for 10 years and it's the only te...
