Monofocal lenses provide clear vision at a single distance, while multifocal lenses correct vision at multiple distances. Monofocal lenses are commonly used for distance vision, while multifocal lenses are suitable for both distance and near vision. The choice between monofocal and multifocal lenses depends on the individual’s visual needs and lifestyle. Monofocal lenses offer sharper…

Triple-negative breast cancer ultrasound shows distinct imaging characteristics, including irregular hypoechoic masses with angular margins, shadowing, and increased vascularity using Doppler ultrasound. Clinically, it presents as palpable masses with rapid growth and a high risk of metastasis. Treatment includes neoadjuvant chemotherapy followed by surgery and radiotherapy. Pathology reveals a lack of expression of estrogen, progesterone,…

Occult breast cancer, diagnosed without a palpable mass, is detected through imaging and biopsy. Treatment depends on cancer stage and can include surgery, chemotherapy, radiation therapy, and targeted therapies. Occult breast cancer poses unique challenges due to its asymptomatic nature and potential for late detection, but advancements in diagnosis and treatment aim to improve outcomes….

Triple-negative breast cancer (TNBC) is a distinct molecular subtype of breast cancer characterized by the absence of estrogen and progesterone receptors and HER2 overexpression. The pathophysiology of TNBC involves alterations in genes such as BRCA1/2, CDH1, and TP53, and activation of signaling pathways including Src family kinase, PI3K/mTOR, and MAPK. Clinically, TNBC is often aggressive…
