Side effects of Radiation Therapy
· Acute and long-term site-specific changes
· Vary according to site
· Local skin changes and hair loss
· Altered taste sensations
· Fatigue
· Bone marrow suppression
Prevention and Early Detection of Cancer
· Limit alcohol use
· Get regular physical exercise
· Maintain a normal body weight
· Have regular colorectal screenings
· Avoid smoking and tobacco
· Get regular mammography screening and Pap smears
· Obtain adequate, consistent periods of rest (at least 6-8 hours a night)
· Use sunscreen of 15 or higher
· Eliminate, reduce and cope with stress
· Eat balanced diet that includes vegetables, fruit, whole grain, and adequate amounts of FIBER
Heath Promotion and Maintenance
· Avoidance of known or potential carcinogens (use skin protection, don’t use tobacco)
· Modifying associated factors (decrease alcohol, high fiber diet, low fat)
· Removal of “at risk” tissues
· Chemoprevention
· Vaccination
· Cancer Screening Guidelines
Problems Caused by Chemo and Radiation Management: hyperuricemia
o Monitor uric acid levels
o Allopurinol may be given prophylactically
o Maintain fluid intake
Problems Caused by Chemo and Radiation Management: cardiotoxicity
o Monitor heart with ECG and EF
o Administer antidysrhythmics as ordered
