contain elevated levels of choline, a product of membrane synthesis, but the Hopkins study is believed to be the first to demonstrate its value in accurately identifying breast tumors. MRSI of the breast does not appear likely to be cost-effective a...

St. Jude/Mayo Clinic study finds direct link between CBP gene and lymphoma
...a narrow set of dysregulated genes." Lymphomas are cancers
of either B-lymphocytes, which produce antibodies, or T-lymphocytes, a group of cells that either stimulate B cells or orchestrate attacks on cancer cells or invading organisms. In this study, loss of CBP only led to T-cell lymphoma. Another unexpect...
Double mastectomies significantly lower risk of breast cancer in women who are genetically at risk

may be related to mutations in the genes BRCA1 and BRCA2. Women can inherit these mutations from their parents, and it may be worth testing for either mutation if a woman has a particularly strong family history of breast cancer. If a woman is foun...
Protein abundant in human tumors confers resistance to anticancer drugs
...of the biology underlying drug action and why some cancers
are drug resistant are not well understood. A research team led by Dr. Donald Kufe from the Dana-Farber Cancer Institute in Boston, Massachusetts examined the role of a protein called MUC1 in drug resistance in cancer cells. The level of MUC1 is subs...
