Dissemination
Dissemination
Dissemination (/dɪˌsɛmɪˈneɪʃən/) is a term used in various fields, including medicine, to describe the spread or distribution of something, such as information or disease, to a wider area or to a larger number of people.
Etymology
The term "dissemination" originates from the Latin word "disseminatus", which is the past participle of "disseminare" meaning "to spread abroad, disseminate". It is composed of "dis-" meaning "apart, in all directions" and "seminare" meaning "to sow, plant".
In Medicine
In the field of medicine, dissemination refers to the spread of a disease or pathogen from an initial or primary site to different areas in the body. It can occur through the blood, lymph system, or other means. For example, in cancer, dissemination often refers to the process by which cancer cells spread from the primary tumor to form tumors in other parts of the body, a process known as metastasis.
