22. A dwarf hamster has a gigantic belly tumour

Nov 11, 2016

Dr Daniel operated on another tumour hamster. Female, 1.5 years old with a tumour under the belly skin at 4 cm x 3 cm. The hamster owner knew the anaesthetic risks and consented to the surgery. The hamster bit my assistant Judy's finger through one cottoned glove. She wore two instead.

A Syrian hamster has a fast growing gigantic neck tumour

Sat Jul 3, 2016

A gigantic fast-growing tumour in this 1-year-old female syrian hamster. The owner texted me for quotation for surgery and anaesthesia. Her vet near her residence had quoted $300 and $300 for after office hour fee. She came to Toa Payoh Vets for surgery.

I was surprised at seeing such a gigantic tumour. Would the hamster die under anaesthesia as it was so large, around 2/3 the size of a golf ball!

Dr Daniel operated. Zoletil 100 IM and isoflurane gas. At one stage, the hamster was not breathing much. Fortunately, all ended well and the hamster is at home now.  A successful anaaesthetic outcome is what builds up the reputation of the vet.  The owner expects no death from anaesthesia and this can be achieved most of the time, if the vet is careful and experienced.

21. Oct 30, 2015. Email diagnosis: A dwarf hamster has a gigantic ear tumour


Hi, I texted one of your colleagues regarding a hamster which I have adopted two days back. Two days back, I adopted two 1~2 year old hamsters from a friend who is migrating overseas. One of the hamsters has a super huge growth on the head where the ear is supposed to be. It looks super painful and uncomfortable.

Also, the hamster seems to be having watery stools and appears deformed. It's fur seems to be yellowish as well. My sister said that it is old, and would probably be better to be put down, but I wanted to check if it could be saved and live a normal life if possible.

 The two hamsters have been at my place for two days. I noticed the one with the huge growth does not seem to eat or sleep much. On query, my friend told me that he had brought it to a vet before when the tumor was smaller. The doctor said it wasn't advisable to operate as it was already old and gave him some ointments which didn't seem to work. He stopped after the fourth visit as the vet seems to be just visually checking the tumor.

He claimed that the tumor continued to grow very quickly despite the ointment and the hamster seemed to be balding, so he stopped administering the ointment to it. I have attached a picture of the hamster with its tumor. Please take a look and provide some advice on what I, or we, can do to help it. I may not check my email regularly, so please so text me at 9xx.

Thank you so much. Regards, J



 I am Dr Sing K Y. Thank you for your email. You posted one view. It appeared to be an ear tumour. If it is purely an ear tumour and the hamster is in good health, lit can be excised. If the hamster is sick (not eating, diarrhoea), the risk of dying under anaesthesia is high and so you have to decide whether you want to take the risk.

Dwarf hamsters get better treatment in Singapore nowadays

August 9, 2014 "I thought it is $60," the mother of a small boy brought her 2-year-old dwarf hamster with a large facial tumour of 8 mm x 6 mm x 5 mm in size. I had quoted $150 - $200 as this surgery would take a longer time and require stitching with the fine 5/0 sutures. Each packet of such fine sutures costs around $10. So she decided not to proceed ahead. After all the hamster is 2 years old and the life span is 2.5 years. Yet there are parents who will bring their children's pet hamster to Toa Payoh Vets for consultation and surgery if necessary. some are the fathers in their late 30s. Videos are at, goto 'HAMSTERS'.

17. Steroids on hamsters

Date: Saturday, April 24, 2010, 5:28 PM


My name is XXX, I have been to your place before and I have 2 hamsters that require some medical attention.

Both are about 2 years old, 1 male and 1 female.

Male suffers from having skin lesions and pus filled abcess in skin folds, I clean him regularly and he is on prednisolone, his conditions fluctuate between good and bad, my previous vet has suggested to keeping him in a high dosage of steroids to keep the inflammation and growth down since not much can be done and he is rather old. However recently he has been losing alot of weight and the situation is worse.

The female one has been very healthy for most of 2 years. However she likes getting into fights. She has a little wound above her right eye cause by a fight that simply wouldnt heal. However, the major problems that she has a pus filled growth in her mouth, it was originally very small and on the outside(with no pus), so I also started her on prednisolone. Only this week did I really she was walking weirdly and lethargic, upon further inspection I realized her her mouth sacs were swollen and there was solid pus on the growth. I cleaned off the pus with cotton wool. Also she has a deep red swell on her abdomen, near her right leg. I use the same syringe for both hamsters, but I wash it before feeding medication to each of them. Also, she bit me about 2 weeks ago while I was feeding her, as I pulled away she fell off from about half a meter on the back.

I was wondering if you will be free for a consult on monday evening.

I can be contacted via


I am Dr Sing. From what you described, the infections have overwhelmed the hamsters due to your use of steroids. I will be available during office hours. If you wish, you can leave the hamsters in my Surgery for daily check and treatment rather than just do it yourself.
