MRI results = Probably benign

My oncologist did not like the wording either. He has he has a meeting not this Friday but next and I will the topic of discussion. He said if he doesn't like the responses, he receives we will do a biopsy just to be sure. Probably is not a diagnosis to a cancer survivor. i will update everyone. Thank you for asking.

What you and @colely say is true but a needle core biopsy is not always the corrects answer. A pet scan is pretty definitive for a survivor who has a much higher anxiety about a “probable” than the a non survivor might.
I had a lump the size of a walnut sticking off of my chest wall and the mammogram came back as negative. 14 cores from a needle core came back negative, my surgeon says “well there is something there and I think we should just cut it out”. Grade 3, estrogen positive, her2 positive invasive ductal carcinoma.
All of this to say, no one procedure is always right, I hope you have a doctor you trust, and build that relationship by asking questions and weighing the recommendations. Then ask for what you need.
I am glad you are following through, do you have another appointment with this doctor? Is the lesion big enough to survive a core biopsy? Should it be excised? Pet scan?

When in doubt, cut it out! I didn't know that a core biopsy would miss cancer, as well as a fine needle biopsy.

Based off my own experience, I would recommend seeing if you can get an ultrasound. A good radiologist can determine if a biopsy is needed based off of the ultrasound results.

Doctors in Australia seem to prefer PET scans. But they don't work if your blood sugar level is too high.

I got a BI-RADS 3, probably benign, reading on an MRI 4 months ago. I was told to wait 6 months and take another MRI to find out of the spot changes. What I've read on pubmed.gov is that this could go on for 3 years, that is, having an MRI every 6 months. I asked why not do an ultrasound-guided fine needle biopsy, and she said that a 0.5 cm spot can't be seen by ultrasound and therefore a biopsy wouldn't work. I'm not sure I believe this as I think she's maybe been wrong about other things. I hate knowing that every MRI leaves gadolinium behind in the bones, brain and other organs, but I guess I'll have to go through with it.

I don't understand myself. I thought the point of having the MRI was to rule out cancer after you have had it. Seems like I am always left with questions unanswered, and wondering am I okay. I pray everything works out for you....

I had exactly the same experience. Fortunately I had a good radiologist who didn't like what she saw on the mammogram, so ordered a diagnostic mammogram, plus ultra-sound. She showed me where I had suspicious calcifications on those tests, then ordered a needle biopsy. She said that 80% of needle biopsies turn out to be benign, but mine was malignant. Turned out to be a 2mm invasive lobular carcinoma. I am very lucky it was found so early. I think one reason they call regular mammograms "screening mammograms" is not that they always find cancer right away (which some do), but that they give hints to the radiologist about possible cancer, which should be further investigated.

Hello, I had a double mastectomy with cancer spreading to my lymph nodes. After having a Diep Flap procedure (remove fat from abdomen and place into breast area) I had a baseline MRI done to establish what would be a normal view of my breasts. The first MRI came back with radiologist explaining he saw things but believed it to be necropsy (dead tissue). After a 6 month waiting period I had the second MRI and nothing had grown so I was considered cancer free. This did cause anxiety but I try to look at it like you cannot change things and will meet them head on if something does occur. Sending you gentle hugs and best wishes for all. ❤️
