On Possible Side Effects
For Patients Receiving Radiation Therapy Treatment to the Brain
Radiation therapy often causes side effects beginning about two weeks after your first treatment. These symptoms may persist throughout treatment but usually fade afterward. Your doctor will inform you about potential symptoms and how to manage them effectively. Follow these guidelines to minimize discomfort:
Skin Reactions
- Skin irritation or redness may develop after 10–12 treatments, sometimes causing itching.
- Wash hair and scalp gently with baby shampoo and use a soft brush or comb.
- Apply pure aloe vera gel to reduce irritation.
- If itching persists, notify your doctor or nurse for prescription options.
Hair Loss
- Hair loss in the treated area typically begins two weeks after starting treatment and regrowth may occur 2–3 months after completion. New growth might differ in texture or thickness.
Before Hair Loss
- Pat hair dry with a soft towel; avoid blow dryers, curling irons and hair sprays.
- Consider getting a wig beforehand to match your hair easily.
After Hair Loss
- Protect your scalp from the sun or cold with a scarf, hat or wig.
- Avoid exposing your scalp to extreme temperatures or direct sunlight.
Fatigue
- Fatigue during treatment is common due to energy use and treatment effects. Plan activities with rest periods and accept help with chores or meals. Quick options like well-balanced frozen meals can be helpful.
Changes in Blood Counts
- Radiation may lower white blood cell and platelet production, monitored weekly or more often if needed. Treatment breaks might be necessary to prevent infection or bleeding. Speak with your doctor if receiving both chemotherapy and radiation.
Other Side Effects
- Report any hearing changes, ear pain or stuffiness to your doctor for medication recommendations. Most side effects are temporary.
If prescribed Decadron (dexamethasone), it helps reduce swelling and inflammation caused by the tumor or radiation. Keep in mind:
- Possible side effects include increased appetite, urination, fluid retention, leg cramps and mood changes. Report concerning symptoms to your doctor.
- Take Decadron with food, milk or prescribed antacids.
- Do not adjust or stop the medication unless instructed by your physician.
For any concerns, always discuss them with your care team. They are here to support you through your treatment.
For Patients Receiving Radiation Therapy Treatment to the Head or Neck (Excluding the Brain)
Radiation therapy may cause side effects starting around two weeks after your first treatment. These symptoms may persist through treatment but typically fade afterward. Your doctor will inform you of potential symptoms and how to manage them effectively.
Pre-Treatment Dental Care
- Visit a dentist for an evaluation that includes cleaning, scaling and any necessary restorations.
- Follow a fluoride treatment regimen with trays or rinse as directed by your dentist and Radiation Oncologist.
Fluoride Treatment Instructions
- Clean your mouth with a soft toothbrush and rinse well.
- Place a drop of fluoride gel in each tray, position over teeth and leave for five minutes.
- Do not eat, drink or rinse your mouth for 30 minutes after.
- Clean trays thoroughly and store them in a dry area.
- Continue fluoride treatments after radiation unless advised otherwise.
Thickened Saliva and Dry Mouth
Radiation can reduce saliva production, causing dryness and discomfort. Manage this with the following tips:
- Use a humidifier or vaporizer in your living spaces.
- Chew sugarless gum or suck on sugarless candy to increase lubrication.
- Drink 4–8 glasses of fluid daily and carry water with you when out.
- Frequently rinse your mouth with a baking soda and salt solution.
- Your doctor may recommend artificial saliva if dryness is severe.
Taste Changes
Radiation can alter taste, making foods seem metallic, bitter or bland. This effect is temporary but can impact nutrition. To help:
- Supplement protein intake with fish, poultry, eggs or dairy if meat becomes intolerable.
- Eat chilled foods like milkshakes, pudding or Jell-O® for easier consumption.
- Prioritize balanced nutrition to maintain tolerance for treatment.
Hoarseness
- Limit speaking when your voice becomes hoarse to aid vocal cord healing.
- Restrict voice use during treatment and for one month afterward.
Skin Care
- Treated areas may develop a "sunburn" effect. Wash gently with mild, unscented soaps like Dove® or Caress®.
- Apply pure, additive-free aloe vera gel 3-4 times daily for soothing relief.
- If you need to shave, use an electric razor to minimize irritation and infection risk.
For any concerns or additional guidance, consult your care team. They are here to support you throughout treatment.
For Patients Receiving Radiation Therapy Treatment to the Chest (Including Patients Being Treated for Lung Cancer)
Radiation therapy may cause side effects that typically begin around two weeks after your first session. These symptoms may persist throughout treatment but usually fade afterward. Your doctor will provide guidance on managing them effectively.
Skin Reactions
- Skin reactions can occur as x-rays pass through to the tumor area.
- Follow your care team's skin care instructions to help minimize discomfort.
Fatigue
- Radiation affects energy levels, leading to fatigue. Plan activities with frequent rest and accept help with household tasks or cooking.
- If you're too tired to prepare meals, try well-balanced frozen dinner options.
Changes in Blood Counts
- Radiation can lower the production of white blood cells and platelets, increasing infection and bleeding risks.
- Blood counts will be monitored weekly, and occasional treatment breaks may be necessary.
- If receiving chemotherapy alongside radiation, counts may require closer monitoring.
Difficulty Swallowing
- Swallowing may become painful or feel obstructed after 2-3 weeks of treatment. Suggestions for relief include:
- Consume soft, smooth or moist foods, and add gravies or sauces for ease.
- Choose cool or room-temperature dishes and avoid coarse, acidic or spicy foods, as well as alcohol and tobacco.
- Eat smaller meals more frequently, aiming for a nourishing and balanced soft diet.
- Liquid antacids may help soothe irritation; consult your doctor about additional medicines.
Dry or Sore Throat
- Throat irritation can occur after 2-3 weeks. To manage this, try:
- Drinking 8-10 glasses of fluids daily.
- Sucking on sugarless candies or chewing gum to increase moisture.
- Using a cool-mist vaporizer to add moisture to the air.
- Gargling with a salt and baking soda solution (¼ teaspoon each in 8 ounces of warm water).
- Avoid smoking, tobacco, and over-the-counter mouthwashes or lozenges, as they may worsen discomfort.
Cough
- A cough can develop due to increased mucus production.
- Stay hydrated to keep mucus thin and easier to expel.
- Your care team can recommend suitable cough medications if needed.
For additional concerns, don't hesitate to reach out to your care team. They are here to support you every step of the way.
For Patients Receiving Treatment to the Abdomen and/or Pelvis (or Those Experiencing Diarrhea)
Radiation therapy to the abdomen or pelvis may cause side effects like nausea, vomiting and diarrhea. These are usually temporary and often subside after treatment ends. Your care team can guide you on managing these symptoms effectively.
Managing Nausea and Vomiting
- Nausea may occur a few hours after treatment, particularly during the first few days.
- Some patients find it helpful to eat a light meal a few hours before radiation, while others may prefer to avoid eating before sessions.
- Vomiting is uncommon and can be controlled with medications prescribed by your doctor.
Managing Diarrhea
- Diarrhea may begin after a few weeks of treatment. Replace lost fluids with low-acid juices like apricot, peach, or pear nectar.
- Avoid high-fiber foods, such as whole grains, raw vegetables, and fruits with seeds or skins.
- If you experience lactose intolerance, consider using Lactaid® milk, lactose-free products or substitutes like soy milk.
- Anxiety may contribute to short-term diarrhea. See your doctor if diarrhea persists beyond a few days.
Recommended Foods:
- Low-lactose milk and cheese (such as Lactaid® or soy milk).
- Refined grains, white bread, rice, cream of wheat or pasta without sauces.
- Cooked vegetables, bananas, applesauce, peeled apples, white or sweet potatoes (no skin).
- Lean, skinless and fat-trimmed meats such as fish, chicken, turkey or veal.
Foods to Avoid:
- Regular milk, beans, legumes and nuts.
- Whole grains, bran and cereals with high fiber.
- Fruits with skins, seeds, or high acidity (such as tomatoes and citrus), raw vegetables, and gas-forming foods like cabbage or cauliflower.
- Greasy, fatty, or fried foods and those seasoned with fresh garlic or onion (use powdered instead).

General Skin Care Instructions During Radiation Therapy
Radiation therapy can cause skin changes such as rashes, scaling, tenderness, blistering or itching. Report these to your primary nurse. Maintaining a balanced diet and staying hydrated is essential for healthy skin during treatment.
Preventing Skin Irritation
- Avoid tight clothing over treated areas (such as belts and bras). Wear soft cotton fabrics.
- Steer clear of irritating products like tape, soap, perfumes, deodorants or talcum powder.
- Do not apply heat or cold (such as heating pads and ice packs) to the area.
- Avoid oil- or petroleum-based products (such as lotions and Vaseline®). Use clear aloe vera gel instead.
- Protect the area from sun exposure with sunscreen and protective clothing.
Tips for Skin Care
- Reep the area dry and exposed to air when possible.
- Substitute cornstarch for powder, and apply lightly.
- Use pure, clear aloe vera gel 2-3 times a day, but avoid powders when using gel.
- Hydrocortisone cream can relieve itching if approved by your nurse.
After Treatment
Skin changes may persist for 1-2 weeks post-treatment. Continue care routines until skin heals completely. Use sunscreen regularly to minimize the risk of skin cancer.
