Hello im suffering from swollen lymph nodes for 6 months in posterior neck. The lymph is 1.2*0.7cm . It is soft and moveable. I also had one lymph node swollen in my groin region which is palpable but ultrasound showed it is 0.5*0.4cm.Im suffering from rectal prolapse for 12,13 years and occasionally blood also comes out while pooping. Can this be the reason for swollen lymph nodes. Fnac of swollen lymph nodes shows feature of reactive lymphadenitis in background of rbc. Can rectal prolapse   be  symtoms of rectal cancer. The size of lymph nodes has remained constant throughout.
