Image: A blood smear from a patient with microcytosis which may predict underlying cancer even in the presence of normal hemoglobin. Microcytic red blood cells measure 6 μm or less in diameter.  The mean corpuscular volume is generally less than 80 fL (Photo courtesy of Sara Beth Fazio, MD).

Microcytosis Is a Risk Marker of Cancer in Primary Care

Microcytosis is a term used to describe red blood cells that are smaller than normal. Anemia is when there are low numbers of properly functioning red blood cells in the body. In microcytic anemia, the body has fewer red blood cells than normal and those red blood cells it does have are also too small. More...

Rare Kidney Cancer Marked by Molecular Features

Renal medullary carcinoma is a rare cancer of the kidney that predominantly afflicts young people of African descent who carry the sickle cell trait, sickle cell disease, or other sickle hemoglobinopathies that can cause sickling of the red blood cells. More...

The mechanism of ctDNA release is unknown, though apoptosis, necrosis, and active secretion from tumor cells have been hypothesized. Once ctDNA is isolated, it can be sequenced for mutational analysis (Photo courtesy of Rachel June Wong).

Blood Test Shows Promise for Predicting Cancer

Early detection of most cancers is an elusive and daunting task; nevertheless, it has remained a top priority for the cancer research community. Detecting cancer early has manifold advantages: it can increase a patient’s chances of successful treatment, prolong their survival, and substantially improve their quality of life. More...

Bacterial Blood Infections Tied to Heightened Colon Cancer Risk

Colorectal cancer occurs in the colon or the rectum and it is the third most common type of cancer in the USA. Around 90% of cases occur in people aged 50 years or older. As well as age, risk factors include a family history of colorectal cancer, some genetic syndromes, obesity, and a lack of exercise, a diet low in fruit and vegetables, and inflammatory bowel disease.

Multicancer Blood Test Aids Screen for Cancer Guide Intervention

As minimally invasive screening tests, liquid biopsies could help reduce cancer-specific morbidity and mortality through earlier detection. However, there is debate on how to effectively screen large populations for cancer, including individuals who do not have symptoms or history of the disease. More...

Biomarker Data Improves Risk Prediction for Pancreatic Cancer

Pancreatic cancer risk prediction models based on clinical factors may be refined and improved by bringing in other types of data, including germline genetic risk variant and blood-based biomarker data. More...

Targeted Next-Generation Sequencing Validated for Lysosomal Storage Disorders Diagnosis

Lysosomal storage disorders (LSDs) are a group of more than 50 inherited rare disorders characterized by the accumulation of specific undegraded metabolites in the lysosomes. This overstorage is commonly caused by a deficient or absent activity of one of the many lysosomal hydrolases or, in a few cases, by the deficit of other non-enzymatic lysosomal proteins. More...
