After skin cancer the most common cancer which can be diagnosed in women is breast cancer. Although breast cancer can occur in both men and women but it is more likely to occur in women. Continue reading “Breast Cancer- What It is and Why You Should be Concerned”
Having dense breast increases the chances of having breast cancer. It is difficult to detect breast cancer in women if she is having dense breast tissue. Continue reading “Advantages of Screening Dense Breast Tissues”
Tomosynthesis is considered to be more advanced than its counterpart as it provides more high-resolution images. Continue reading “Tomosynthesis v/s mammography: What is the difference?”
Biomarkers are biological characteristics that are measured objectively and evaluated as indicators of normal biological processes, pathogenic processes or pharmacological reactions to therapeutic intervention. Continue reading “Importance of Protein Biomarkers”
Breast cancer is a leading cause of death among women in the U.S., but good evidence is tantamount to early detection of breast cancer death. X-ray mammography screening remains the most sensitive non-invasive technique to detect early tumors when women are asymptomatic and cancers may still be non-invasive. Limitations that reduce sensitivity and specificity are inherent in all medical tests, and mammography has been reported to be missing 10%-15% of breast cancers.
Federal standards, along with significant technological improvements, have resulted in improved requirements for regulation, inspection, and compliance. Refinements continue to be made in film/screen combinations, but a narrow dynamic range limits the ability to achieve the high contrast needed to resolve fine structures with only minor differences in density.
X-ray screening mammography remains the most sensitive non-invasive technique for early tumor detection, although regular enthusiasm for other non-radiation imaging cancer detection methods such as thermography, diaphanography (light scanning), whole breast ultrasound, and magnetic resonance imaging (Breast MRI). While additional methods may refine mammography screening or clinically based impressions, they do not address conventional mammography’s reliability, low cost, and efficiency as a mass screening test for large populations.
During this time, mammographic equipment, technical performance,and skills of radiologists have improved, but radiologists still need to balance the need for high sensitivity for mammographic abnormalities (high detection of cancer) with high specificity (reduction in the number of false positives leading to callbacks and biopsies for findings that are ultimately not cancer).Radiologists ‘ observational lapses persist and are not, surprisingly, closely linked to experience. The tendency to err is all too human and cannot possibly be completely eliminated. This has spurred research into radiologist development aids. Computer-assisted detection (CAD) and digital mammography are notable.
Ductal carcinoma in situ (DCIS)
This is the most common type of non-invasive type of breast cancer. Ductal refers to cancer that starts in the milk ducts, carcinoma refers to any cancer that begins in the skin or other tissues, and in situ means “in its original place.” Continue reading “Different Types of Breast Cancer”
A false positive is where you get a positive test result if you ought to have a negative result. A “false alarm” or “false positive error” is sometimes called. It is usually used in the medical field, but it can also apply to other arenas (such as software testing). Continue reading “False positive results and The False Positive Paradox”
