Lesion

What does lesion mean?

Lesion is a word pathologists use to describe any abnormal cells or tissues. Some lesions can be seen without the aid of a microscope while others can only be seen after the tissue is examined under the microscope.

Types of lesions

Common types of lesions include:

  • Tumours (non-cancerous and cancerous).
  • Traumatic injuries.
  • Infections.

Lesion is a general description and not a diagnosis. Your pathology report will provide more information about the lesion which will allow your doctors to determine the cause.
