>I have never been the type of stutterer that can speak perfectly when speaking alone. There's just a few types of words I cannot say in any circumstances. I see a lot of stutterers making a significant distinction between stutters that occur when you're alone and stutters that disappear during the same circumstances. I can't know how your tumor is effecting your speech, but I wanted to point out an inability to achieve fluency when alone does not make your stutter (or the root cause of it) distinctly different from others. It's just one of my big pet peeves in the community, a lot of misinformation surrounding that. I don't want someone to read stuff like this and think, "I still stutter even when I'm alone, omg maybe I have a tumor." It's likely you don't! Some stutters are just more severe or less impacted by social communication than others. In any case, if your doctor says the tumor could have been a factor, then that has far more weight than anything I have to offer. The more important question is whether that possibility shifts your own view of having a stutter or not. If your tumor was the catalyst, but your brain and body have adapted into a stutter, does that make it any different from a stutterer without a tumor? That's not something I can definitively answer, although I'd wager not. But how you feel about it is what's most important.
