My mum was diagnosed with breast cancer last Thursday (16th July) she had a lump under her arm & one on her breast, she had 4 mammograms & an ultrasound done on the Tuesday & we were informed on the 16th that she was to go for an MRI which she had yesterday (22nd July) we received the news today that they now want her to go for a ct & bone scan!! I am now terrified but the Dr informed us this was just a precaution......should we be worried??
