Depends on what algorithm it uses. I'm attaching one interpretation where I try to emulate the magic wand tool in Photoshop.

The above code didn't help me. Just help me find the problem in following code and this is the code for region growing https://in.mathworks.com/matlabcentral/answers/334356-how-can-i-implement-the-followinng-function-in-the-matlab-code-and-how-to-process-the-attached-image

We already solved that. You insisted on using kmeans and I showed you how to get every class, including the tumor. Using region growing for an image that is already labeled into classes is pointless. The labeling process in essence already did the region growing so there is no need to repeat it. You're done after that.
