Tumor Treating Fields (TTFields)

Type: Medical Term

Definition:
Tumor Treating Fields (TTFields) are a non-invasive cancer treatment that uses low-intensity, alternating electric fields to disrupt the division and growth of cancer cells, including those in mesothelioma.

Phonetic Pronunciation:
(TOO-mur TREE-ting feeldz)

Etymological Origin:
The term "Tumor" originates from the Latin word tumor, meaning "swelling" or "growth." "Treating" is derived from the Old French traitier, meaning "to handle or manage." "Fields" refers to the electric fields used in this therapy. The term collectively describes the use of electric fields to manage tumor growth.

Significance in Asbestos Context:
TTFields are significant in the context of asbestos-related diseases because they represent a novel treatment option for malignant pleural mesothelioma, a cancer caused by asbestos exposure. This therapy specifically targets cancer cells without harming normal cells, offering a less invasive alternative to traditional treatments like surgery or chemotherapy. TTFields have been approved for use in mesothelioma and are often used in conjunction with other therapies to improve patient outcomes.
