In med terminology, sclerosis/sclerotic means "hardening." "Lesion" is kind of generic term used for many types of damaged tissue. A lesion does not mean cancer; although some lesions are cancerous. "Sclerotic lesion" basically means an area of damaged tissue that has hardened. If this condition was diagnosed by your doctor, he/she is the one to discuss it with. :)

No, lesion is just a term for a localized area of damage. So it could be anything: ulcer, abscess, wound, infection, contusion, or tumor (though think about it - is a back injury or bone cancer more likely?)
Sclerotic means it's slow-growing. So, for example, you fractured your vertebrae and it's been building up a little knot of bone as it heals.
