Breast radiation - discharge
You're having radiation treatment for breast cancer. With radiation, your body goes through some changes. Knowing what to expect will help you be prepared for these changes.
Radiation - breast - discharge
What to Expect at Home
You may notice changes in the way your breast looks or feels (if you are getting radiation after a lumpectomy). These changes include:
- Soreness or swelling in the area being treated. This should go away around 4 to 6 weeks after treatment is over.
- The skin on your breast may become more sensitive or numb.
- Skin and breast tissue may be thicker or firmer. The skin may be slightly darker.
- After therapy, your breast may feel larger or smaller. Many women will not have any change in size.
- You may notice these changes for up to 12 months after therapy starts.
Take care of the treatment area:
- Wash gently with lukewarm water only. DO NOT scrub. Pat your skin dry.
- DO not use heavily scented or detergent soaps.
- Do not use lotions, ointments, makeup, perfumed powders, or other perfumed products on this area unless recommended by your health care provider.
- Keep the area that is being treated out of the direct sun.
- Do not scratch or rub your skin.
Tell your provider if you have any breaks, cracks, peeling, or opening in your skin. DO NOT put heating pads or ice bags directly on the treatment area. Wear loose-fitting breathable clothing.
Wear a loose-fitting bra with no underwire. Ask your provider about wearing your breast prosthesis, if you have one.
You need to eat enough protein and calories to keep your weight up while you are having radiation.
Tips to make eating easier:
- Choose foods that you like.
- Ask your provider about liquid food supplements. These can help you get enough calories. If pills are hard to swallow, try crushing them and mixing them with some ice cream or another soft food.
Watch for these signs of swelling (edema) in your arm.
- You have a feeling of tightness in your arm.
- Rings on your fingers get tighter.
- Your arm feels weak.
- You have pain, aching, or heaviness in your arm.
- Your arm is red, swollen, or there are signs of infection.
Ask your provider about physical exercises you can do to keep your arm moving freely.
Most people who get radiation treatment begin to feel tired after a few days. If you feel tired:
- Do not try to do too much in a day. You will probably not be able to do everything you are used to doing.
- Try to get more sleep at night. Rest during the day when you can.
- Take a few weeks off work, or work less.
