Degenerative disease of lumbar spine.

 Hello doctor, My mother is diagnosed with the above said problem.Attaching MRI report  medication.Dr.Ramakrishna reddy,Guntur advised for surgery and he said that it's a minor surgery.But before that we approached another doctor he said that spine surgery is very critical n there's chance that while removing the tumor  surrounding nerves may get damaged n patient can be paralysed.Now we are scared to go for surgery n my mother is under medication n suffering from pain.Also she has slight knee deformity n bcoz of this she has  difficulty to walk r to climb steps.As per her age n considering other factors is it ok to go for surgery or  shd we go for second opinion.will it b an open surgery or thru laparoscopy,please suggest.what r the complications involved if we go for surgery and later implications also...or else is there any other way out to cure it possibly with medication.kindly advise.
