I had a lumpectomy for ILC in late July followed by a 25/5 radiation course. I’ve been put on Tam 1.5 months ago.
I had a breast ultra sound two days ago. The radiologist noted a small lesion that she graded BIRAD 4C. She recommended an ultra sound true cut pathology. My surgeon seconded this opinion saying there is a probability this is a new malignancy. The question is how could this have gone undetected only two months ago when I had the mammogram, US and MRI? The doctor said it could have been very small to be detected and the radiation actually made it grow. Does this make sense? Radiation treatment supposedly kills any rogue cells not form new tumours. Am I missing something!?
Please help answer my questions. I’m worried sick.
