Treatment of tumors and abscesses in guinea pigs


Most often, to maintain the health of the guinea pig, it’s sufficient in size and clean cage, a large amount of clean water with the addition of vitamin C, fruits, vegetables and dry food. If all these conditions are met, the result will most likely be a healthy and happy mumps that will live the period allocated to it (from 5 to 8 years). Unfortunately, sometimes guinea pigs get cancer, like other animals.

This is the most common type of tumor found in guinea pigs. It is believed that the cause of this disease is a retrovirus. In pigs with lymphosarcoma, lymph nodes in the neck increase. As the disease progresses, other lymph nodes increase. Swelling of the liver and / or spleen may begin. In some animals, leukemia begins.
The diagnosis can be made based on the results of a biopsy taken from the lymph node. In addition, usually in the blood of a sick pig, the number of leukocytes increases sharply. The prognosis, unfortunately, is unfavorable - most sick animals cannot be cured. Nevertheless, it is worth trying high doses of prednisone as therapy. But the condition of most pigs worsens and after 2-5 weeks they die.

Lungs' cancer
The most common lung tumor in guinea pigs is benign adenoma. She does not give metastases, but, nevertheless, represents a threat to life. Adenoma most often appears on the edges of the lung and gradually grows. By the time the diagnosis is made, most of the lung tissue is most often affected and it is difficult for the pig to breathe. Nothing can be done at this stage.
The reason this disease is often impossible to cure is because a healthy looking pig is rarely given x-rays. If an X-ray is still taken and a small tumor is detected, it may be removed surgically. In this case, the animal is likely to recover.

Breast tumor
Breast cancer is not so common in guinea pigs, but nevertheless, it occurs in both females and males. Most often, it appears in elderly pigs and almost never occurs in animals younger than 3 years old.
The guinea pig has two mammary glands located between the hind legs. A tumor usually affects only one of them. Usually these are benign fibroadenomas that do not secrete metastases. Surgical removal of the tumor in such cases leads to a complete cure of the animal. In approximately 30 percent of cases, a breast tumor is a malignant adenosarcoma. But even in these cases, surgery can save the life of the animal.

Skin cancer
Guinea pigs are predisposed to certain types of skin tumors. Most often, basal cell skin cancer occurs on the hind legs of the animal. This is a slowly growing tumor, usually oval. Over time, it can turn into an open festering wound. At this stage, infection may occur.
Treatment is surgical removal, it is highly desirable to produce it before the appearance of a wound. The operation usually leads to a complete cure, since this type of tumor gives metastases extremely rarely. Basal cell carcinoma often has a genetic origin, and is found in several generations of animals.

Bladder cancer
This is a fairly rare type of cancer. Most often, it makes itself felt with blood in the urine. In such cases, the pig is usually prescribed a diet rich in iron, as well as vitamin B - this helps prevent anemia from losing blood. If the tumor has already become too large, doctors usually recommend euthanasia.

Pig Care

The health of the mumps largely depends on the conditions of detention. These animals require a spacious cage (30x40 cm and a height of 50 cm). Inside is placed a house, toys, a wheel, ladders - objects that will provide the pet with an active pastime. As litter, sawdust or a special filler is used, which is changed 2 times a week or as it becomes soiled. The cage and bowls must be washed regularly.


On average, guinea pigs live 8 years. They have strong immunity, so they rarely get sick. In general, rodent diseases are divided into the following categories:

  • mechanical damage caused by a fall, shock, bite of another animal,
  • infections transmitted by bacteria, viruses, parasites,
  • Diseases caused by a violation of the diet or maintenance: digestive problems, obesity, etc.,
  • genetic pathologies.

A swine in a guinea pig is not uncommon. Unfortunately, their appearance is mainly due to genetic reasons independent of the owner.

Malignant and benign tumors

The main cause of tumors in pigs is genetic. If the animal has formed cancerous tumors, most likely they will recur in its descendants. There is a theory that cancer is more likely to affect individuals suffering from obesity caused by malnutrition. Externally, the tumor looks like a bump on the back, neck or elsewhere. If such a formation is noticed on the body of the pet, the animal should be shown to the veterinarian.

Malignant tumors are characterized by rapid growth and the appearance of metastases (the spread of new tumors throughout the body). They grow in different places, often on the mammary glands or testes. Benign formations are surrounded by a partition that does not allow them to grow. Due to this, they are successfully removed without relapse. Incurable tumors become the basis for euthanasia. Otherwise, the pig will need regular doses of pain medication and constant care.

An abscess is a purulent abscess on the body. It appears as a result of physical trauma: an injection from sawdust, branches, a strong bruise. Damage triggers inflammation in organs or other soft tissues. For example, due to the growth of the roots of the teeth, a bump appears on the cheek. In the process of inflammation, pus accumulates, which forms an abscess. Over time, the abscess opens and pus comes out.

An abscess is treated with ichthyol ointment or an iodine grid: they are spread on the neoplasm and a dressing is applied on top. These actions help pus "mature" faster. When the abscess is opened, its edges are smeared with a solution of chlorhexidine or anti-inflammatory ointment until complete recovery. At the same time, the pet is given vitamin C to speed healing. An abscess can be opened at the veterinarian under sterile conditions and with the use of anesthesia. Incorrect treatment leads to the fact that the formation grows and opens inside the body, releasing pus into the bloodstream.

Tumors of Guinea Pigs with Tumors

There are many diseases that lead to the formation of tumors. A lump on the neck is a sign of lymphosarcoma, which involves the tightening of the lymph nodes in the neck, armpits and groin. Over time, the liver and spleen are affected. If treatment is absent or does not give a positive result, lymphosarcoma will lead to death.

Lung cancer is caused by a benign adenoma - a tumor on the back or on the sides. Diagnosis is carried out using x-rays. Of the external signs, shortness of breath is observed. In the early stages, it is easily removed surgically. But at a late stage it is incurable: the formation captures most of the lung tissue and becomes inseparable. In addition to lung cancer, a lump appearing on the side may indicate the development of liver or kidney cancer. The disease is accompanied by a lack of appetite, lethargy, as well as bloody discharge from the anus or genitals.

Breast tumors are common in guinea pigs. They are found in both females and males (their mammary glands are present in their infancy). They are usually benign and do not leave metastases in other organs. The lesions are excised during surgery. At risk are individuals of older age - older than 5 years. The disease should be suspected if the pet has a lump on the stomach. In some cases, fistulas and abscesses form.

Osteosarcoma - the formation of growths on the ribs and bones of the limbs. Typically, such pathologies are malignant in nature and suggest the amputation of the affected limb, if there are no metastases in the internal organs.

Lipoma and wen in a guinea pig are benign formations. Outwardly, they look like dense cones under the skin. They do not require surgical intervention, unless they cause the pet inconvenience or grow at a rapid pace. In any case, the decision on the need for surgery is made by the veterinarian after a biopsy.

Consult your veterinarian

Tumor growth cannot be stopped without the help of a veterinarian. The doctor conducts a medical examination that helps determine the presence and type of cancer. Timely contacting a specialist increases the chance of a successful outcome of treatment up to 70%. Otherwise, the mumps with the tumor will live no more than three years. Therefore, you should not waste time treating your pet with "folk" means like a hemlock or vegetable oil.

After surgery, the animal is prescribed a course of drugs aimed at restoring immunity and stopping the spread of infection.

Mumps are difficult to tolerate serious surgery. Regular preventive examinations help 1-2 times a year to prevent treatment that is difficult for a pet. The examination reveals the disease at an early stage, when treatment requires less effort and cost.

The appearance of tumors is a serious pathology. Even benign formations are fatal if untreated. Regular visits to the veterinarian for a routine examination help to prevent serious consequences. The owner must pay attention to the health and appearance of the pet in order to catch the alarming signs.

Guinea pig abscess and its treatment

An abscess is a capsule with pus that, after ripening, thins the walls of the capsule and ruptures out. For the treatment of an abscess, Ichthyol ointment or Vishnevsky ointment is used, which is lubricated abundantly with a tumor, and left for a day, covered with a plastic wrap and a bandage. There is no need for a bandage if the mumps does not reach the tumor. The ointment accelerates the process of pus maturation and in a day the opening of the abscess begins. The edges of the opened wound are treated with hydrogen peroxide, cleansing it of pus, leaving it open. With a good immune system, the wound cleans completely and closes in a day. At this time, you need to give vitamin C to the pig, and consult your doctor about the treatment process.

How to distinguish malignant tumors from malignant neoplasms?

Benign tumors grow slowly and are not life threatening. These tumors are limited, often on the stalk and are easily separated from the surrounding tissues.

Of the common tumors in guinea pigs, the following are often found:

  • Skin cancer. It often occurs on the skin of the hind legs, sometimes on the sides and back. If removed on time, then relapse may not be.
  • Tumors of the mammary glands. May occur in both males and females over the age of 4 years. To a greater extent, they are benign and are removed without metastasis.
  • Lungs' cancer. A benign tumor and, precisely because of this, is most dangerous for life because at the beginning of its formation it does not give strong signs and is not detected. After an X-ray examination, a biopsy is prescribed, which can establish a type of neoplasm. In the later stages, the tumor grows into all the lungs and its removal is no longer possible.

Malignant tumors often begin with swollen lymph nodes in the neck, and then in the groin, and armpits. Then there is an increase in the liver, spleen, leukemia develops, and the animal dies. A tumor that proceeds this way is called lymphosarcoma. This usually happens with those animals whose parents also died from the development of cancer processes. There is a genetic predisposition of the body to this pathology.

To determine the type of tumor in a guinea pig, you should consult a doctor. The diagnosis can be made by conducting a medical examination. Tumors are removed surgically, after which treatment is prescribed that is aimed at increasing immunity, and antibiotics to stop the infection. With the development of oncology after 3 years, the life of a pig ends in a sudden fatal outcome. With timely surgical intervention to remove benign tumors in 70%, the outcome is favorable.

Guinea pigs are difficult to tolerate surgery, especially when their body is greatly weakened. Therefore, we recommend that owners daily examine their pets, examining the skin, so as to promptly call a doctor for a consultation.
