I checked and nothing came up.
I dunno. Just searched on "tumor" by Title (Date) and it showed. You're not the first person to experience this, though.
I'd just read the article this morning-- that's the only reason I thought to check. Probably wouldn't have posted anything but there were 100+ comments on the other thread I wouldn't want anyone to miss.
Been guilty of the same thing myself-- so I'm definitely not throwing stones!
It often helps to try a couple searches for different important words in the title. Sometimes people search for "keywords," but that doesn't work unless someone has inserted the keyword into the thread by clicking on "Click to add a keyword." Often no one has added the right keywords.
The earlier post showed up in my search and you can see that here:

Sometimes the searches don't seem to work quite right, no matter what one does and even if the person who is posting is, like you, considerate enough to do a search.
