Hamster with tumor: what you need to do now

If your hamster has a tumor, it doesn’t have to mean a death sentence.

Because a tumor can be just as benign and can be treated or at least continue to allow a pain-free life.

What you can do always depends on the individual case. Here you get an overview and everything you need to know.

In this article you will learn how to recognize a tumor in your hamster, when you should go to the vet, and what can be done.

How can you recognize a tumor in your hamster?

When you hear the word tumor, you may immediately think of cancer. However, this is not necessarily the case.

The word “tumor” simply means a localized increase in tissue.

This can manifest itself as a lump or nodule under the skin, but can also be positioned on an organ. In the case of a noticeable tumor, diagnosis and treatment are much easier.

Tumors on the internal organs are much more difficult to detect and are often only noticed when they have reached an enormous size or cause other symptoms.

But how can you recognize a tumor? The following symptoms are clues:

Changes in behavior
Movement restrictions

Tumors can also break open, creating visible wounds on the body, sticking to the coat, or bleeding.

If the tumor is in the mouth, it may prevent normal feeding. In the nose, it can restrict breathing, and in the bladder, it can interfere with the passage of urine.

The position is therefore crucial for the effects and therefore also for the symptoms.

For changes in behavior or health, you should always consider that a growth could be the trigger.
How is a tumor in a hamster examined?

If you notice a lump or other discomfort in your hamster, you should see a veterinarian immediately.

Growths are common in animals and are not always malignant – but they still need to be treated immediately.

Because they can grow quickly, significantly shorten the life of your animal or cause pain.

It is therefore better to seek immediate clarification than to wait. Tumors can not only be malignant or benign.

A lump can also be a very painful abscess, which can be fatal within a few days due to inflammation and the accompanying fever.

For these reasons, the growth is not only palpated.

A measurement of the body temperature and a biopsy or, if necessary, direct removal of the tumor under anesthesia are possible measures.

It may also be useful to perform an imaging procedure – such as X-ray. This helps to assess the extent of the tumor.

What is the treatment for a tumor?

Unfortunately, there is no general answer to this question. The therapy depends on the type of tumor and how far it has spread.

If it is still limited and can be easily removed, a minor surgical intervention is sufficient.

If, on the other hand, it has already spread – metastasized in the technical language – your animal can unfortunately only be kept pain-free.

However, even with this it is often possible to give a hamster a few more pleasant weeks or months.

What additional treatment is useful?

Unfortunately, there is little you can do if you have a tumor. However, you can strengthen the immune system.

Simple means and measures are sufficient for this.

Pay attention to your diet:

A balanced diet can strengthen the entire body and increase well-being.

A vitamin-rich diet and sufficient water are therefore important.


You must avoid stress as much as possible, because hamsters are extremely sensitive to it.

This has a negative effect on their health and can even negatively influence the success of treatment with medication or surgery.

You should urgently avoid loud noises, hectic or many changes.


Parasites and pathogens can additionally worsen the state of health.

Therefore, make sure that the bedding is changed regularly, that the drinking water is clean and fresh, and that fresh food is not left in the hamster’s home for too long.

Otherwise, mold may form, insects may be attracted or diarrhea may be caused by dangerous bacteria.

Keeping your hamster in a species-appropriate manner is the basis for good health and, if necessary, healing after surgery.
When should you have your hamster euthanized?

Tumor treatment, by removal or medication, is only advisable when your hamster is pain free with it.

The small rodents get used to many things. For example, they can cope even if one eye had to be removed.

However, it is crucial in any case that your animal does not suffer. Good clues for this are the following questions:

Does your hamster eat well and with appetite?
Does the animal drink enough?
Does it move normally?
Does it react aggressively or apathetically?

Just because your hamster needs medication or has a lump does not necessarily mean it should be put down.

With proper care and therapy, quality of life can be maintained. If it is in pain or has other problems despite these remedies and measures, euthanasia may be a salvation.

Frequently asked questions

Can tumors be prevented?

No, unfortunately a reliable prevention is not possible. However, you can reduce the risk by keeping your hamster in a species-appropriate manner.

In addition, you should choose a hamster with a verifiable origin and pay attention to cleanliness and sufficient exercise.

If you also scan your animal regularly, you have achieved a very high level of prevention.

What can cause tumors in a hamster?

As with humans and other mammals, tumors can arise from a variety of influences. Harmful factors include:

unzureichende Versorgung mit Nährstoffen
Giftstoffe, wie Nikotin, Reinigungsmittel oder Abgase
Anhaltende Entzündungen
genetische Veranlagung

Some of these you can avoid. Others, unfortunately, are hereditary and therefore cannot be cured or changed.

Are tumors in hamsters always cancer?

A helpful clue is that benign tumors in hamsters are clearly demarcated. Cancer, on the other hand, first spreads to the surrounding tissue and can metastasize.

If this has already occurred, the hamster often dies in a short time. Until that time, he can still have a nice life.

If your hamster has a tumor, you should not panic. The growths can now be well operated on and treated with medication.

In addition, you can take preventive measures and also initiate treatment.

It is best to consult a veterinarian experienced with rodents.
