You need to demonstrate your code so that we can see what objects you are talking about.

@Matt J i want to circle the center of cancer ( after i circle all the cancer )

We're missing the jpeg file. I ran your code to expose the error we see when we try to run it.

I have no idea of the radius or center location of the circle you want to draw because you forgot to attach the image. But usually viscircles will do what you want.

If your version is too old for viscircles, see the FAQ: https://matlab.fandom.com/wiki/FAQ#How_do_I_create_a_circle?

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
