My grandmother, who is 64, had breast cancer and had one of her breasts removed. She was ok until recently, and supposedly, she had regular follow-ups but mom tells me they now suspect liver and lung metastases. Granny had a lot of pain in the chest and was coughing all the time and they discovered a spot on her lung. They say this is how lung metastases shows up but I don’t know why they are suspecting liver metastasis. She is about to have some more testing. Can you tell me the symptoms of lung and liver metastases? How are they treated?
