개의 지방종:지방종은 위험합니까?

강아지의 목, 가슴, 다리 또는 등에 덩어리가 밤새 나타났다면 당황하지 마십시오. 많은 애완 동물 부모는 개가 암에 걸리는 것을 두려워하지만 최악의 시나리오로 넘어가기 전에 수의사와 약속을 잡고 덩어리를 평가하십시오. 지방종일 수 있습니다.

지방종은 개의 약 16%에 영향을 미치는 일반적인 유형의 종양입니다. . "종양"이라는 단어가 무섭게 들릴 수 있지만 이러한 비정상적인 성장은 양성 지방 축적이며 일반적으로 무해하다는 것을 아는 것이 중요합니다.

지방종(지방종)이란 무엇입니까?

지방종이라고도 하는 지방종은 주변 지방과 다른 속도로 성장하는 지방 침착물에서 발생하여 개의 피부 아래에 덩어리를 형성합니다. (인간도 이해한다). 뚜렷한 덩어리는 종종 부드럽고 움직일 수 있으며 일반적으로 아래 근육에 붙어 있지 않습니다. 종양은 일반적으로 잘 캡슐화되어 경계가 정의되어 있어 필요한 경우 외과적으로 쉽게 제거할 수 있습니다.

지방종은 보통 무해한 , 그러나 겨드랑이 아래 또는 사타구니와 같은 특정 위치에서는 이동성을 제한할 수 있습니다. 대다수는 양성이며, 이는 암이 아니며 악성 종양이 할 수 있는 방식으로 몸 전체에 퍼지지(또는 전이되지 않음) 의미합니다. 그러나 일부 개는 평생 동안 신체의 다양한 위치에 여러 지방종을 형성합니다.

침윤성 지방종이라고 하는 보다 공격적인 형태의 지방종도 있습니다. . 이러한 유형의 성장은 여전히 ​​양성이지만 경계가 덜 정의되어 수술로 제거하기가 더 어렵습니다.

참고:"지방종"은 림프절의 매우 공격적인 형태의 암을 나타내는 개의 림프종과 매우 유사하지만 같지는 않습니다.

지방종이 암이 될 수 있습니까?

매우 드문 경우지만 지방 종양은 실제로 지방육종이라고 하는 악성 종양입니다. . 이러한 유형의 암 덩어리는 지방 세포에서 발생하고 빠르게 자라며 매우 국소적으로 침습적이지만 전이하는 경우는 거의 없습니다. (또는 퍼짐) 신체의 다른 부위로 퍼집니다.

지방육종은 제거하기 위해 적극적인 수술이 필요합니다. 불행히도 종양의 크기, 위치 및 침습성에 따라 완전히 제거하는 것이 불가능할 수도 있습니다. 이러한 경우에는 방사선과 같은 추적 치료가 권장됩니다.

What does a lipoma look like?

Lipomas usually start as a small, round bump under the skin. The size of the lump will depend on how much fat the tumor contains, but canine lipomas can appear quite large. Usually, they’re soft and somewhat movable, although firmer masses or ones that are more firmly attached to the underlying tissues are also common.

Fatty tumors often appear on dogs’ neck, leg, chest, and back. Many dogs develop multiple lipomas on the body at once. Obese dogs tend to develop larger lipomas than others, and the fat deposits might shrink with weight loss, but typically do not disappear completely.

What causes fatty tumors in dogs?

The exact cause of lipoma in dogs is not yet fully understood. They are more likely to occur in mid- to senior-aged dogs over eight years old. Overweight adults are especially at risk .

Some dog breeds are more prone to lipomas than others, including:

• Dachshunds
• Beagles
• Doberman Pinschers
• American Cocker Spaniels
• Miniature Schnauzers
• Weimaraners
• Labrador Retrievers

Diagnosing lipomas in dogs

Lipomas cannot be diagnosed by palpating, or feeling, the lump. If you notice a lump on or under your dog’s skin, you should schedule an examination with your veterinarian. They will perform a full physical examination and may take measurements of the lump.

Your veterinarian will likely recommend a fine-needle aspirate (FNA) to determine the type of cells that form the lump. An FNA is a minimally invasive, quick test that can be performed in the clinic. Your veterinarian will insert a small needle into the lump and remove some cells with a syringe.

These cells will be placed on a slide and examined microscopically by your veterinarian or a veterinary pathologist. Aspirates typically cost between $50 and $200 depending on whether the cells are sent to a pathologist for review.

It’s important to note that this test only samples a small number of cells in what is sometimes a very large lump beneath dogs’ skin, so it may not be 100% accurate. Pet parents should continually monitor all lumps for changes in texture, size, and appearance, and call your veterinarian if you notice changes like these.

How to treat canine lipomas

The majority of fatty tumors in dogs are harmless and do not require treatment . In most cases, monitoring the lump for changes over time is the best approach. There is no reliable medical therapy for lipomas. To get rid of a dog’s lipoma completely, it must be surgically removed. This requires general anesthesia, which does carry some risks and is generally not recommended for cosmetic purposes only.

Veterinarians usually recommend surgical removal of a lipoma if the lump is big enough to:

• Impede the dog’s movement
• Interfere with normal body functions
• Cause discomfort

Rarely, adipose tumors might become infected or injured, in which case, surgical removal is usually the best option. If the lipoma becomes locally invasive, surgical removal may need to be followed by radiation therapy to help limit regrowth.

Canine lipoma removal cost

Surgical removal is usually several hundred dollars per lump , which will include pre-anesthetic testing (such as bloodwork), anesthetic medications, an intravenous catheter, surgical removal, surgical supplies, and post-operative medications.

The cost of surgical lipoma removal will vary based on the size of the mass and its location. The size of your dog and the duration of surgery may increase the cost of removal. If the lipoma is very big, highly invasive, or in a difficult-to-access spot, then surgery expenses can reach or exceed $1,000 — especially if a board-certified surgeon performs the surgery.

Your veterinarian will likely recommend that any tissue removed at surgery is sent to a veterinary pathologist for a biopsy. This test will confirm that the lump is indeed a lipoma and there are no other abnormal cells within the mass. For infiltrative lipomas or liposarcomas, a biopsy will be necessary to determine if the surgeon was able to get clear margins, meaning there are no tumor cells present microscopically at the edge of the removed tissue.

프로 팁: Many pet insurance plans cover the cost of diagnostic tests and physical examinations essential to ensuring your pup’s health, with reimbursement rates as high as 100%.

Recovery and prognosis

In most cases, a lumpectomy to remove a lipoma is an outpatient procedure, meaning your dog will come home the same day. In rare cases of more invasive lipomas, your vet may recommend overnight observation.

Most lipomas are fairly easy to remove because of their well-defined borders, though the incisions can be quite large depending on the tumor size. In some cases, your veterinarian may place a drain under the skin to prevent fluid from building up at the tumor removal site. This drain will need to be monitored and removed several days after surgery.

Once your pet is home, you’ll need to administer anti-inflammatory medication and dog pain relievers per the directions provided by your vet. Do not use over-the-counter medications. Your vet will also likely send home an Elizabethan collar (E-collar or “cone of shame”) to ensure your dog doesn’t bite, lick, rub, or scratch the incision. Doing this can delay healing and lead to infections. You will also need to monitor the incision site for swelling, bleeding, redness, or irritation.

Most lipomas are easily removed with surgery and rarely recur, though they can form in other locations. Unfortunately, regrowth rates following surgery for malignant growths are higher, with a 36% recurrence rate for infiltrative lipomas . In some cases, follow-up therapy, such as radiation, is recommended.

Can lipomas be prevented?

Researchers do not yet definitively know what causes lipomas in dogs, so it can be challenging to prevent them from occurring. Overweight and obese dogs are more likely to develop adipose tumors, so maintaining a proper weight through exercise and diet may help.

주요 요약

• Lipomas are fatty tumors located under the skin and can occur on any part of a dog’s body. They’re typically harmless unless they interfere with the animal’s mobility due to their location.
• Although lipomas can appear on any dog, older and overweight pets are at a greater risk.
• Lipomas are diagnosed with a fine needle aspirate, and most have no impact on the dog’s overall health, so removal is often unnecessary.
• Although the majority of lipomas are benign, there are more aggressive and malignant forms so you should have all lumps checked by your veterinarian.
• Pet insurance can help to cover the costs of diagnosing and removing a lipoma.
