Post-treatment Follow-up

After the treatment, the patients might experience problems in chewing, eating, or talking. If this happens, then rehabilitation or “rehab” is recommended wherein the doctors, nurses, and other health professionals would work together with the patient to help him chew, eat, and talk normally. After treatment, your doctor will check you every so often to see if the cancer comes back. Follow-up tests can include exams, blood tests, and imaging tests. Regular post surveillance has become an essential part of the care of patients after they are treated of head and neck cancer. Patients should be counseled so as to look for any possible signs of tumor recurrence.
