My wife has had a couple of lesions on her liver for several years, with little change. A needle biopsy seven years ago showed them as benign.
Since then, she has had stage 1 grade 9 HER2+ breast cancer. After six months of chemo and a year of Herceptin, her latest PET scan shows increased SUV in both liver lesions. One is 1.5 cm with a SUV of 5.5, and the other is 2 cm with a SUV of 8. Both of these sound very high, but the CAT scan shows no growth, even though the PET shows a little growth.
What are the chances that these are benign?
We see the oncologist in two days, so we'll get answers them, but my poor wife is not dealing well with the news.
