My husband is a 5 yr cancer survivor (35 yrs. old, 5'8, 320 lbs, very active, farmer), Hodgkins Lymphoma. routine check up in December = scans normal - released to go one year til check up with blood work only. This weekend we found we are concerned with puffiness around lumphnode that was biopsied (right side neck, above collar bone) also where his port was - right side, very sore in that area. we have a sched. appt. with oncologist because of concern, is this something that can occur??
