Researchers have identified a new compound, GW5638, that strengthens bones and improves cardiovascular health like natural estrogen, while stopping the growth of cancer in uterine cells. The compound's potential may replace tamoxifen as a treatment for breast cancer.
A new gene, AIB1, has been discovered in breast cancer cells that amplifies their growth. The gene is part of a family known as SRC-1 and interacts with steroid hormone receptors, enhancing tumor cell growth.
Researchers at Johns Hopkins Medicine found that the TSG101 gene, previously identified as a tumor suppressor, was consistently normal and undamaged in human breast cancer cells. The cells exhibited abnormal RNA splicing, which may be a result of cancer cells trying to activate normal cell behaviors in an abnormal way.
Researchers discovered that abnormal expression of the WT1 gene is linked to nearly 70% of breast cancers, which may lead to new treatments. The study suggests restoring functional tumor suppressor genes like WT1 could help combat breast cancer.
A non-invasive method for distinguishing between different types of tumors has been developed by Prof. Hadassa Degani at the Weizmann Institute. The approach, known as the Three Time Point method, uses MRI to monitor the uptake and clearance of a contrast-enhancing dye-like material in tumor tissue.
A study published in Cancer found that women with breast cancer who received care at a multi-disciplinary clinic had definitive treatment within 29.6 days, compared to 42.2 days for those seeing specialists sequentially. Patients are also more satisfied with their care, wanting quick resolution and comprehensive support.
A new study by University of North Carolina at Chapel Hill researchers found that black women are half as likely to report ever having had a mammogram and 17% less likely to have had one in the past year compared to white women. The single strongest predictor of whether a woman undergoes the test was her doctor's recommendation, which ...
A review finds existing studies on pregnancy after breast cancer treatment are inconclusive due to biases and limited data. Researchers stress the need for more research to determine potential effects of estrogen levels on tumor growth in pregnant women.
The study identifies mutations of P-TEN in advanced brain, breast, and prostate cancers, suggesting a new potential target for cancer treatment. The discovery represents one of the first genes implicated in aggressive brain tumors.
The new technique allows doctors to find the sentinel lymph node, reducing swelling and side effects. In over 90% of cases, the sentinel lymph node is found, offering women more effective treatment with fewer complications.
A long-term epidemiological study found that postmenopausal women with the highest bone mass have a 3.5 times increased risk of developing breast cancer compared to those in the lowest quartile of bone mass. The study suggests that high bone mass may be associated with increased exposure to estrogen, which is linked to breast cancer de...
Developed by Rensselaer Polytechnic Institute, adaptive current tomography (ACT) aims to improve breast cancer screening without radiation exposure. The system uses electrical conductivity and permitivity measurements to detect tumors, offering advantages over X-ray mammography.
Researchers have identified an inactive gene that contributes to cancer development when it fails to work in harmony with the tumor-suppressing p53 gene. The findings suggest that the bax gene can act as a tumor suppresser, and its dysfunction may lead to increased cancer cell death and tumor growth.
Researchers at ORNL have developed a technique that combines laser light with pharmaceutical agents to selectively kill breast cancer cells. The laser delivers photons to the target tissue, activating an ingested agent that disables DNA replication and halts tumor growth.
Researchers at UNC-CH and Penn State University have identified a gene called KiSS-1 that controls the spread of malignant melanoma in laboratory mice. This finding may help doctors distinguish between tumors that will colonize other organs and those that will not.
A new UB study published in JAMA reveals a strong association between smoking and breast cancer risk in postmenopausal women with the slow-acting NAT2 gene. Women born with this genotype who smoked more than a pack of cigarettes per day before menopause had seven times the risk of developing breast cancer.
A new study reveals that the BRCA2 gene mutation is found in one out of every 100 Ashkenazi Jews, increasing their breast cancer risk. The risk is more than three times higher for those who inherit the BRCA1 mutation compared to BRCA2.
The joint venture aims to improve the ability to diagnose, control, and cure cancers by identifying gene defects and relating them to treatment responses. Memorial Sloan-Kettering's retrospective database and Sequana's gene discovery platform will be combined to achieve this goal.
Researchers at UCLA's Jonsson Comprehensive Cancer Center are testing the safety and effectiveness of TNP-470, an experimental drug that prevents tumor growth by blocking the formation of new blood vessels. The study aims to reduce tumor size and prevent cancer spread in patients with metastatic breast cancer.
A new study by epidemiologists at the University at Buffalo found that premenopausal women had a 29% lower risk and postmenopausal women a 24% lower risk of breast cancer if they had breast-fed for at least 12 months. The positive effect was found only for those who first breast-fed before age 25.
A study published in the Journal of Nutrition found that rosemary significantly inhibited the binding of a known cancer-causing agent to DNA in mammary cells, reducing tumor formation by 76 percent in rats fed a diet supplemented with 1 percent rosemary.
Researchers at Duke University and the Institute for Cancer Research have located a second breast cancer susceptibility gene, BRCA2. This gene is expected to account for most of the remaining 50% of inherited breast cancers not caused by BRCA1. Women who inherit BRCA2 are at an 85% risk of developing breast cancer.
