2. In the facts you narrate, the case seems quite open and shut. The level of radiation treatment was simply much too great. However, I caution you, that unless you have a supporting expert medical report, you cannot issue legal proceedings. Be aware that most medical negligence solicitors will be retained on the basis that no charge will be made apart from the costs associated with getting the supportive expert medical report. Then if that report is favourable, proceedings can be issued and the case progressed. If not, that will be the extent of charges.
