  • Lymphoedema. Some women who have had surgery in their armpit are likely to get a swelling in the arm after radiotherapy to this area. Nowadays, specialists do not recommend having both surgery and radiotherapy to the armpit due to the increased risk of lymphedema expect if the lympho nodes involve cancer cells.
  • Breathlessness. Rarely, patients can get a continuing cough or breathlessness some years after radiotherapy. This is due to the fact that radiotherapy causes unpredictable changes in the lung tissue called radiation fibrosis.
