hi, i'm new to this and i'm really confused. i had a right breast lumpectomy. clear nodes and margins,lump was 3cm. docs suggested chemo , rads and tamoxafen. i had a really strong feeling against chemo. i took one treatment of 4. i had some side effects,and lost all my hair,which i'm dealing ok with. now they want me to do 33 radiation treatments, i am concerned about the effects on my heart and lungs. the doctor said i could get lung cancer or lose up to 15 % lung function on that side. i just don't know what to do they said this is for precautions, in case there was a stray cell,i just don't know what to think. 50-50 chance without rads. 5% with,but it could cause cancer somewhere else and that lung cancer isn't as curable. has anyone else had this kind of confusion. and how long until hair starts regrowing? any input will be appreciated.
