Trastuzumab

Trastuzumab is a monoclonal antibody used to treat certain cancers, including lung cancer linked to asbestos exposure.

TTF-1 (thyroid transcription factor-1)

TTF-1 is a biomarker used to identify the origin of lung cancers, aiding in distinguishing primary lung adenocarcinoma from metastatic cancers.

Tumor Necrosis Factor-alpha (TNF-α)

A cytokine involved in systemic inflammation and the acute phase reaction.

Tumor Treating Fields (TTFields)

Tumor Treating Fields (TTFields) is a cancer treatment using low-intensity electric fields to disrupt cancer cell division, often used with chemotherapy for asbestos-related diseases.

Tumorigenesis

The process by which normal cells transform into tumor cells, often leading to cancer.

Tunica Vaginalis

A thin sac that surrounds the testicle and lines the inner surface of the scrotum.

Twinned Crystal

A crystal structure where two or more individual crystals share a common lattice, resulting in a symmetrical intergrowth.

Ultramafic Rocks

Igneous and metamorphic rocks with very low silica content and high levels of iron and magnesium, often containing asbestos minerals.

Ultrasound

A diagnostic imaging technique using high-frequency sound waves to visualize internal body structures, useful in detecting asbestos-related conditions.

VEGF inhibitors

VEGF inhibitors are drugs used to treat asbestos-related cancers by blocking the formation of new blood vessels that feed tumors.

Venue

The geographic location where a legal case is heard, crucial in asbestos litigation.

Vinorelbine

Vinorelbine is a chemotherapy drug used to treat cancers linked to asbestos exposure, such as non-small cell lung cancer.

Workers’ Compensation

Insurance providing wage replacement and medical benefits to employees injured by asbestos exposure in the workplace.

WT-1 (Wilms Tumor 1)

A gene involved in cell growth regulation, often altered in asbestos-related mesothelioma.

X-Ray Diffraction (XRD)

A technique used to identify the crystalline structure of materials by measuring the scattering of X-rays from a sample.
