Invasív

Invasív is an adjective used in several European languages to describe something that invades or spreads into another area. Its etymology traces to Latin invasio and invadere, with spelling and pronunciation varying by language (for example invazív or invasív forms in different linguistic contexts).

In biology and ecology, the term is most commonly associated with invasive species or invasive plants. An invasive species is a non-native organism that establishes, spreads, and causes ecological or economic harm in a new environment. Examples often cited include species such as the zebra mussel in North American waters, kudzu in parts of the United States, and giant hogweed in Europe. The invasiveness of a species is influenced by factors like rapid growth, high dispersal ability, and lack of natural predators, and management typically involves prevention, early detection, rapid response, and control measures.

In medicine, invasiveness refers to the degree to which a procedure or disease penetrates tissues or enters the body. Invasive procedures breach barriers such as the skin or mucous membranes, including surgeries or catheter insertions, in contrast to non-invasive methods. In oncology, invasive cancer describes tumors that invade surrounding tissues and may metastasize, unlike non-invasive tumors that remain localized, such as in situ carcinomas. The term is also used to describe imaging or treatment approaches that cause tissue disruption versus those that are non-invasive.

Overall, invasív denotes a continuum from limited disruption to extensive tissue or ecological impact, and it is commonly contrasted with non-invasive or minimally invasive alternatives.
