Patients with the following diseases can be accepted despite less than 5 years disease free interval: carcinoma in situ of the cervix, melanoma in situ, basal cell carcinoma of the skin, squamous cell carcinoma of the skin
  • The patient has an indication for boost to 1 or more regional nodes
  • Previous radiotherapy to the chest region
  • Patient enrolled in another therapeutic trial. Observational cohorts are accepted if the collection of data does not interfere with the current trial
  • Pregnant or lactating
