This can happen for many reasons. It will continue growing, but it might change shape on you. It is not likely to cause any real harm to your tree though.
I would recommend a little wettable sulfur and dolomitic lime as it looks like you may have the start of an infection as well. Make sure to only water when the top of the soil is almost completely dry.
