surgery necessary?

53 yr old female, 6 spine surgeries (4 laminectomies, 2 fusions L3-L5,S1).
New MRI shows moderate-severe narrowing of the central canal L1/L2 with mild mass effect on the right thecal sac, abutting the traversing nerve roots.  There is associated narrowing of the right neural foramen at L1/L2.
Multi-level degenerative changes seens in the cervical spine, most significant at C5/C6 and C6/C7 with apparent moderate bilateral neural foraminal narrowing at C6/C6, left greater than right.

Please tell me (in 5th grade english) what exactly all this means.  I had been told in 2005 that there is desiccation of the T6/T7 intravertebral disc with a small central discherniation posteriorly and inferiorly into the epidural space causing minimal mass effect on the anterior thecal sac.
No mention of this now.  Did this disc herniation simply disappear ?
