Hello FML friends, I've been a ferret dad since 1995 and a subscriber to the FML since 1996. Like many of us we come to depend on the FML, BIG, and those readers who take the time to pass along stories, medical information, and so much more. Due to my own health problems I haven't posted to the FML since 1998 but I still read the FML as often as possible. In 1997 I found a lump on the upper lip of one of my 2 male ferrets, Bandit and Kirby. Our vet removed the lump and as much of the surrounding tissue as was possible and sent it off to be analyzed. This came back as squamous cell carcinoma and the vet said there were no clear margins which indicated that the cancer had spread beyond the lip area. Unfortunately, Bandit developed 3 huge fast growing tumors in his abdomen and when it became apparent that he was in pain we had him euthanized. About 10 months, Kirby, his "brother" developed a tumor on his lip... same size, same place and we had this removed as soon as we found it but in the end Kirby, too, went to be with Bandit at Rainbow Bridge. We thought that since they were litter mates that could be a link in explaining how they could both develop a tumor on the lip. That was, until now. After Bandit died, we adopted an 8 month old female Sable from the Humane Society to keep Kirby company. Last Friday I was giving Sammi her weekly "physical" and there, in her mouth, on the upper lip was a tumor about the size of a pencil eraser. I hadn't noticed it the week before and now, Sunday, I again checked it and it has increased in size by nearly 50%. She is scheduled to be seen in the morning at the vet hospital. We have tried to think of anything that all three ferrets have in common. It always seems to come down to food, water, air, cage and litter. They all ate either Deli-Cat or Totally Ferret or a mix of both, our water is from our well (this has been tested and other than being hard no problems found. We do NOT have a water softener). The air outdoors here in Bangor, Maine is great and inside, we don't smoke or burn wood, so I have sort of ruled this out too. The 3 story cage has carpeting on the top level (sleeping area) and newspaper covering the wire mesh on the lower levels. The litter I use is Tidy Cat and none of our fuzzies root around, dig, or play in the litterbox. They all got doses of Ferretone and FerretVitae. Bandit and Kirby both had ECE but Sammi never seemed to ever come down with that. Has anyone had a ferret develop a tumor in the mouth? Any ideas on the cause of these tumors? Our vets didn't prescribe any medications after the removal of the tumor. I don't know if we can bear losing another of these wonderful critters and although we all love our ferrets I wouldn't want to put another one at risk if this is caused by something in its environment here. It makes us wonder if it is something here, in our home, that my family is being exposed to! My wife is a breast cancer survivor, now 5 years and 4 months and counting since the surgery, chemo and radiation with no reoccurrence! We built our home 27 years ago and this area, just west of Bangor, Maine was all farmland 100 years ago and there is a significantly higher cancer rate in both the people and domestic animals according to some surveys. There have never been any studies done on what might be causing this in this specific area. Any ideas on what could cause all three of my ferrets to develop tumors on their lip or about increasing Sammi's chance of survival after she has the tumor removed, would be greatly appreciated. Sorry this is so long, BIG. I re-wrote it a dozen times until I got it down to this size. Thank you. Take care. Sincerely, Bruce Skakle Bangor, ME [log in to unmask] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is the pathology report on Kirby's tumor. Histopath Report: Source: Gingiva above right upper canine; gray white tissue(s) less than 1cm - all processed. Description: The small biopsy fragments reveal an ulcerated, stratified squamous muccosa. Present within the submucosa, and extending to the deep margin are cords of downward proliferating anaplastic squamous epithelial cells. The nests or cords of cells reveal significant anisocytosis and anisokaryosis. Many karyomegalic cells with prominent nucleoli are observed, and mitotic figures are consistantly encountered 1-2/hpf. The fibrocollagenous stroma separating the proliferating epithelial cells is inflamed. Diagnosis: SQUAMOUS CELL CARCINOMA. Prognosis: Guarded, with potential for local invasion and distant metastasis. Comments: The morphology of the tumor cells was consistant with a relatively high grade squamous cell carcinoma. Long-term epidemiology studies are not available in this species for this tumor; however, continued locally aggerssive growth and metastasis would both be considered possible. Wide surgical excision, if possible, is recommended. Borders: All deep and lateral borders consist of affected tissue. [Posted in FML issue 2981]
