There are two ways you can deal with this.
If the news item is only going to be displayed on the front page, use a chunk.
Then you can edit the chunk as needed. If you prefer, you can create a document with no template to hold your news item, and use a TV with @DOCUMENT binding to display the news item.
You could even just use the home page’s "Summary" (introtext) field to hold the news item.
On the other hand, if the news item is to be a brief summary of a regular news page (usually this would be the latest news page), which will also be displayed as part of a list of news summaries with links on a main "News" page, just use a Ditto call on the home page.
