Invasive carcinoma of breast

Invasive carcinoma of breast (ICD-11 2C61): breast cancer that has spread beyond the ducts or lobules into surrounding tissue. Main types are invasive ductal carcinoma (70-80%) and invasive lobular carcinoma (10-15%).

Invasive ductal carcinoma of breast

Invasive ductal carcinoma (IDC), also called infiltrating ductal carcinoma or invasive breast carcinoma of no special type (IBC-NST), is the most common breast cancer, about 70-80% of cases, starting in milk duct lining and invading surrounding tissue.

Invasive earthworms of North America

Invasive earthworms of North America are introduced, mostly European and Asian earthworms colonizing temperate and boreal forests that native earthworms have not occupied since the last ice age.

Invasive glucose monitoring

Invasive glucose monitoring measures blood glucose by sampling body fluid directly, either fingerstick blood on test strips or subcutaneous continuous glucose monitoring (CGM) sensors reading interstitial fluid.

Invasive lobular carcinoma of breast

Invasive lobular carcinoma (ILC), also called infiltrating lobular carcinoma, is the second most common breast cancer type, arising in milk-producing lobules, marked by E-cadherin loss, diffuse growth, HR-positive disease, unusual metastatic sites, and late recurrence.

Invasive mechanical ventilation

Invasive mechanical ventilation is life support that pushes gas into the lungs through an endotracheal or tracheostomy tube, maintaining gas exchange and protecting the airway in respiratory failure.

Invasive mole

Invasive mole (chorioadenoma destruens) is a malignant gestational trophoblastic neoplasia in which molar villi invade the uterine myometrium, usually after a complete hydatidiform mole, causing persistent hCG; treated with chemotherapy, it may regress spontaneously.

Invasive non-typhoidal salmonellosis

Invasive non-typhoidal salmonellosis (iNTS) is bloodstream infection by non-typhoidal Salmonella enterica serovars such as Enteritidis and Typhimurium, causing an estimated 2.1–6.5 million annual cases, highest in sub-Saharan Africa among children with malaria, malnutrition, or HIV, with 14.5–25% case fatality and no licensed vaccine.

Invasive pests of conifer forests

Invasive pests of conifer forests are insects and pathogens moved by human activity outside their native ranges that attack pines, spruces, firs, and hemlocks, causing more than $70 billion in damage yearly.

Invasive prenatal testing

Invasive prenatal testing is the set of procedures, chiefly chorionic villus sampling (CVS) and amniocentesis, that sample fetal cells for definitive diagnosis of chromosomal conditions.

Invasive species

Invasive species (invasive alien species, IAS): organisms introduced by humans outside their natural range that harm biodiversity and economies. Over 37,000 alien species recorded, 3,500 invasive; $423 billion annual cost in 2019; key role in 60% of extinctions.

Invasive spiders and biosecurity in Australia and Oceania

Invasive spiders and biosecurity in Australia and Oceania concerns non-native spiders establishing there or intercepted as cargo hitchhikers, notably the redback's spread to New Zealand and Japan.

Invasive vagus nerve stimulation

Invasive vagus nerve stimulation (VNS) is a neuromodulation treatment in which a surgically implanted pulse generator stimulates the left vagus nerve, FDA-approved for drug-resistant seizures and treatment-resistant depression.

Invasive weed optimization

Invasive weed optimization, also known as the invasive weed optimization algorithm, is a population-based metaheuristic for numerical optimization introduced by Mehrabian and Lucas in 2006.
