Background: The molecular studies indicate some of the genes in the promoter region itself, will undergo methylation. Methylation of CpG islands in the promoter region of that cause silence or reduced expression of genes involved in cell growth pathways, which are colorectal cancer causing agents. Detection of methylation status can be used as a marker for cancer diagnosis and prediction of dis...

Introduction: Breast cancer is an uncontrollable growth of abnormal cells in different areas of the chest. Research about the causes of breast cancer is crucial. Finding cancers risk factor can lead to identification of women at risk, prevention strategies, and screening for early detection of disease. In this paper, we tried to survey the risk factors that lead to the creation of this common c...

Introduction: Early diagnosis of gastric cancer is the best solution for reversing cancer and curing patients. So far, gastric cancer is diagnosed in late stages due to misinterpretation of symptoms or absence of specific symptoms. Highly sensitive and selective detection methods for biomarkers are needed for early detection. Methods: This paper proposed a new fast screening method, based on t...

Objective: The annual incidence of cancer in the world is growing rapidly. The most important factor in the cure of cancers is their early diagnosis. miRNA, as a biomarker for early detection of cancer, has attracted a lot of attention. Methods: In this study, an electrochemical biosensor was developed to detect the amount of miR-106a, the biomarker of gastric cancer, by modifying a glass...

background: colorectal cancer is one of the most common cancers and second leading cause of cancer deaths worldwide. every year nearly one million new cases of colorectal cancer are recognized around the world and nearly half of them lose their lives due to the disease. researches shown that in early diagnosis of this cancer 90% of patients can be treated. the fecal occult blood test (fobt) bec...

Reduction mammaplasty is increasingly used for the treatment of discomfort associated with macromastia. Breast cancer is a tumor with the highest prevalence and incidence in women. As it can be expected, reduction mammaplasty specimens occasionally reveal breast cancer. So, before reduction mammaplasty, patients should be assessed for breast cancer risk and evaluated by physical examination a...

prostate cancer is a major cause of morbidity and mortality in iran, yet there are few studies examining risk factors specific to the iranian context. we conducted a case-control study to explore risk factors for prostate cancer in mazandaran, iran from 2005 to 2008. the cases were 137 men with clinicopathologically confirmed prostate cancer. controls were 137 neighborhood and age match men wit...

Cancer detection tests open a new era of developing cancer markers, allowing early and improving treatments. Existing technologies, for example, CA125, CA 19.9, CT, MRI, others, are either not highly sensitive or specific enough detection. Recent technological development “liquid biopsy” research led to more biomarkers. Newly developed multiple-cancer early-detection can screen up multiple canc...

mri of the breast has evolved as a non-invasive imaging modality and is ideally suited for several indications e.g. pre-operative staging and screening in women at increased risk for breast cancer. the widespread use opens also the discussion on over-diagnosis if only 20 - 30 out of 100 mri - guided breast biopsies lead to the diagnosis of breast cancer. thus mri based strategies are needed to ...
