Is this a canker on my Chamaecyparis?

Hi Folks,

Is this a canker on my Chamaecyparis nootkatensis? If it is what can I do? What is the likelihood of this spreading to my other C. nootkatensis?

Thanks,

Looks like bark damage (possibly mechanical), followed by wound occlusion growth.

 

Thanks Michael,

That is a relief, I really don't want to have to take this tree out.

Thanks again,

C.
