I am currently in remission from breast cancer I had lump removed in November 2005 and first Chemo on December 15th 2005 and had four rounds finished Feb 26 of 2006. I had 63 rounds of radiation finished in April 11,2006. I am currently taking Arimidex 1 mg. I am 56 and was born with cerebral palsy. (mild case lower legs only ) I am experencing lack of balance,severe joint pain and weakness. Has there been any research of the long term effects of chemo or the medication on persons with CP? Thank you for any information
