A few words of thanks would be greatly appreciated.

Nodule - Definition

Nodules are abnormal growths, usually round, that accumulate on the surface of tissue or in an organ. They can be cutaneous, located under the skin and usually detectable by touch in the form of small, relatively solid bumps. Nodules can also be found in certain organs, detectable only by the symptoms they cause or by imaging scan. In these cases, they are most often benign tumors, but can sometimes be cancerous or become so. It is not, as a rule, necessary to remove benign nodules, except if they cause painful pressure on an organ or nerve. A cancerous nodule must be treated, and this is usually with surgery, depending on its location.
