TheCA-125 blood testis used to detect the level of the protein, CA-125, which is referred to as a “tumor marker.” This test can sometimes be helpful in identifying ovarian cancer because cancer cells in the ovary release this protein into the body. However, there are other conditions not...
Discusses research being done on blood test for levels of circulating tumor cells. Reference to study by M. Cristofanili et al, which appeared in the 2004 issue of "The New England Journal of Medicine"; Findings of the test for levels of circulating tumor cells of patients with metastatic ...

“We’ve found something that we can detect before breast cancer develops, so as a risk marker, this is really what we want to find.” People with a high level of abnormalities are at high risk.Humphrys asked, “So you’re going to be able, potentially, fairly soon, to be able to...
PROGNOSTIC MARKER A characteristic of a patient or tumour at the time of diagnosis that can be used to estimate the chance of the disease recurring in the absence of therapy. MULTIVARIATE ANALYSIS A statistical test that examines more than two variables at the same time. ...
Differences were observed in all blood marker categories, from on-therapy until years post-chemotherapy. Associations were found between cognitive functioning and (1) blood markers (mainly inflammation-related) during, shortly-, or years post-chemotherapy and (2) white and gray matter metrics in ...
Proteomics of blood samples is a promising avenue for cancer diagnosis. Here, the authors conduct Mendelian randomisation analysis of protein levels across multiple cohorts, and identify 5 proteins that show promise as biomarkers for the long-term risk of breast cancer, and as potential drug targets...
Methylation levels from the tissue were conserved in the ctDNA, indicating that methylation clocks are a stable marker of cell fate. We applied the same regression method that we used to calculate the contribution of different sites to ctDNA from whole-genome sequencing data. We found that the...
Because screening mammography for breast cancer is less effective for premenopausal women, we investigated the feasibility of a diagnostic blood test using serum proteins. This study used a set of 98 serum proteins and chose diagnostically relevant subse
Cancer prevention has a profound impact on cancer-associated mortality and morbidity. We previously identified TGFβ signaling as a candidate regulator of mammary epithelial cells associated with breast cancer risk. Here, we show that short-term TGFBR in
