Mammography can detect cancer early when it’s most treatable and can be treated less invasively (thereby helping to preserve quality of life). According to National Cancer Institute data, since mammography screening became widespread in the mid-1980s, the U.S. breast cancer death rate, unchanged for the previous 50 years, has dropped well ...
A suspicious area on mammography or ultrasound. [9] This may include: Microcalcifications on MRI. [10] BI-RADS score of 4 or 5 on mammography, ultrasound, or MRI. [11] A suspicious hard palpable lump [9] Skin changes like crusting, scaling, or dimpling of the breast, which may signal an underlying breast cancer [9] Abnormal nipple discharge [7] [9]
The natural distribution of causation for primary hyperparathyroidism is roughly 85% solitary adenomas, 10-15% diffuse hyperplasia, and 1% cancer. Imaging is not as reliable in patients with multiglandular parathyroid disease. In addition, size limitation of the abnormal gland can limit the detection by radionuclide scanning.
2D ultrasound, Doppler ultrasound and especially CEUS can play an important role in pretherapeutic staging, particularly when sectional imaging investigations (CT, MRI) provide uncertain results or are contraindicated. During the interventional procedure, ultrasound allows guidance of the needle into the tumor.
Elastography is a type of ultrasound examination that measures tissue stiffness and can be used to detect tumours. [7] Breast ultrasound is also used to perform fine-needle aspiration biopsy and ultrasound-guided fine-needle aspiration of breast abscesses. [8] Women may prefer breast ultrasound over mammography because it is a painless ...
The procedure involves taking a core of trabecular bone using a trephine, and then aspirating material. Breast: Breast biopsy is often performed to assess or diagnose breast cancer, and can be performed by various methods such as fine needle aspirate (FNA), core needle biopsy (CNB), or surgical removal.

The surgeon then removes these lymph nodes and sends them to a pathologist for rapid examination under a microscope to look for the presence of cancer. A frozen section procedure is commonly employed (which takes less than 20 minutes), so if neoplasia is detected in the lymph node a further lymph node dissection may be performed. With malignant ...
