Lymphedema
Radiation to the axilla (underarm area) can cause abnormal swelling in the arm. This is called lymphedema, and is more common if underarm lymph nodes have been surgically removed. In rare cases, radiation therapy may weaken the ribs, which could lead to a fracture.
In the past, parts of the lungs and heart were more likely to get some radiation, which could lead to long-term damage of these organs in some patients. Modern radiation therapy equipment allows doctors to better focus the radiation beams, so these problems are rare today.
A very rare complication of radiation to the breast is the development of another type of cancer called angiosarcoma. These rare cancers can grow and spread quickly.
