3-D Doppler Ultrasound Helps ID Breast Cancers
By Julie Steenhuysen CHICAGO (Reuters) - A broad analysis of genes has turned up 26 mutations linked with the most common form of lung cancer, several of which play a role in other cancers as well, researchers said on Wednesday. The findings, published in the journal Nature, double the number of genes already linked with lung adenocarcinoma,

TUESDAY, Oct. 21 — Radiologists can now better distinguish malignant and benign breast masses by using three-dimensional power Doppler ultrasound, a new report says.
Blood flow through malignant breast masses is often higher compared with normal tissue or benign masses. The Doppler ultrasound allows radiologists to detect vessels with higher flow speeds, which likely indicate cancer.
The study will be published in the November issue of Radiology.
“Using 3-D scans promises greater accuracy due to more consistent sampling over the entire tumor,” lead author Gerald L. LeCarpentier, an assistant professor in the department of radiology at the University of Michigan in Ann Arbor, said in a news release from the Radiological Society of North America. “Our study shows that 3-D power Doppler ultrasound may be useful in the evaluation of some breast masses.”
The study showed 3-D Doppler ultrasound to be highly accurate in identifying malignant breast tumors in examinations done on 78 women, aged 26 to 70, who then had a biopsy on a suspicious breast mass. Combined with age-based assessment and grayscale visual analysis, 3-D Doppler was 100 percent accurate in identifying cancerous tumors and had a specificity of 86 percent in excluding benign tumors.

NEW YORK (Reuters Health) - A mastectomy is prudent when breast cancer returns after a lumpectomy, because survival rates are better than with another lumpectomy, according to a new report. “We were surprised to find that so many women in our study — almost a quarter of them — had received another lumpectomy rather than a

FRIDAY, Oct. 17 — Mammograms detect 80 percent to 90 percent of breast cancers in women without symptoms, and all women 40 and older should get a yearly mammogram, says the American Cancer Society (ACS) as it marks National Mammography Day on Friday, Oct. 17. “Mammography remains the most effective screening test for the early detection
