Lesion means an area of change in tissue.
When doctors use the word lesion, they are describing something that looks different from surrounding tissue. A lesion can be caused by many things and does not automatically mean cancer or something dangerous.
Lesion is a descriptive word, not a diagnosis.
Doctors most often use lesion to describe:
Inflammation or irritation
Injury or trauma, current or past
Infection-related changes
Scar tissue
The meaning of a lesion depends on location, size, and appearance.
Some lesions cause no symptoms and are found on imaging.
When symptoms are present, they may include:
Pain or tenderness
A lump or visible change
Swelling
Skin changes
Symptoms related to the affected area
Symptoms vary widely based on where the lesion is.
No. Most lesions are not cancerous. The word simply means an area looks different and needs description or evaluation.
Doctors often use lesion when they want to describe what they see before knowing the cause.
Lesions can involve inflammation or irritation, which may cause discomfort even when not serious.
Yes. Some lesions resolve as inflammation heals or the body recovers from injury or infection.
Doctors may evaluate lesions using:
Imaging such as ultrasound, CT, or MRI
Physical exams
Monitoring changes over time
Biopsy in some cases
The goal is to understand the cause, not assume the worst.
Many lesions are managed by a primary care doctor.
Dermatologist – for skin lesions
Radiologist – for imaging interpretation
Surgeon – if biopsy or removal is needed
Specialist related to the organ involved
Referral depends on findings and symptoms.
For many people, next steps may include:
Monitoring the lesion
Follow-up imaging
No treatment if stable
Further evaluation only if changes occur
Most lesions are monitored rather than treated aggressively.
