The number/make up of the cells they found put me in a "suspicious" category. My GYN kept watch on me every 3 months to see if there were any changes, put me on some meds. About 2 years and procedures after that, I ended up having an ablation to take care of some bleeding issues. Eighteen months after the ablation, I had another biopsy because I was having problems again. That biopsy came back as endometrial adenocarcinoma Grade 1 and prompted my surgery (total hysterectomy). So it was about 5 yrs from my initial "suspicious" biopsy result to being diagnosed with early grade/stage cancer. There had always been a chance that the hormones he put me on would have resolved the issue, but that wasn't the case. I know several friends who have had suspicious cervical biopsies that resolved over a year or two and had only been monitored.
There may be suspicious cells, but as my Dr. told me, any biopsy is only as good as the speck of tissue removed. Apparently years ago, the volume of bad to good cells was very very low and only 1 sampling was done. Did they sample multiple spots with your husband's biopsy? That would be a good question to ask. My last biopsy in February (15 yrs after the original diagnosis/surgery), the interventive radiologist sampled 5 different places in and around the mass. I am currently finishing up a years worth of treatment - 4 rnds chemo, surgery, 2 rnds chemo, 25 rnds external rads (I'm almost halfway through this phase), then 3 rnds internal rads.
It's a shock to hear, or even think, that "C" word. It throws you for a loop. My oncologist and GYN both encouraged me to do my own research once I was diagnosed and discuss options with them.
I hope that the suspicious cells clear up for your husband. Sending positive thoughts to both of you!
