Cankers are usually oval to elongate, but can vary considerably in size and shape. Typically, they appear as localised, sunken, slightly discoloured, brown-to-reddish lesions on the bark of trunks and branches, or as injured areas on smaller twigs. The bark often splits between the diseased and the healthy tissue, and sometimes it may ooze sap or moisture. Cankers are formed by the interaction between the host and pathogen. The pathogen grows within the wood and the host tree tries to contain the growth.
