Inspired by an article by Ms. Prof. Dr. Daniela Simon Betz, Dipl. ECVIM-CA Today we will examine oncology in veterinary medicine and common misconceptions in veterinary oncology:
Introduction
In the Oncology in veterinary medicine There are numerous misconceptions and misunderstandings that can unsettle both pet owners and professionals. These misconceptions often concern the behavior of tumors and the effects of diagnostic or therapeutic measures. In this article, we aim to clarify some of these misconceptions to alleviate anxieties and promote effective diagnostics and treatment for our animal patients.
Behavioral errors: On dormant and awakening tumors
In previous parts of our mini-series, we have already told several stories about the Oncology in veterinary medicine Today we will address misconceptions concerning tumor behavior that are frequently the subject of discussion. Our goal is to enable efficient and targeted diagnostics and therapy through education.
Myth 1: Palpation can cause a tumor to grow and become malignant.
The concerns of pet owners
Imagine the following situation: A family notices a subcutaneous lump on their dog and, concerned, takes it to the veterinary clinic. After a general examination, we want to examine the swelling more closely to assess its consistency, size, and any potential tenderness. But suddenly, a family member expresses concern that palpating the lump could "awaken" the tumor and cause it to become malignant. They've heard of a case where a tumor suddenly grew and "spread" after an examination.
The facts
These fears are understandable, but unfounded. There are no scientific evidence, Manual manipulation of a tumor can cause it to awaken from a dormant state and grow faster or become malignant. The cell division rate and growth of a tumor are influenced by factors such as cell type, malignancy, cell cycle position, size, and blood supply. Palpation does not affect these factors.
Exception: Mast cell tumor
One exception is the Mast cell tumor In dogs, palpation can lead to the release of histamine and other inflammatory mediators. This results in swelling, redness, and possibly itching or pain in the affected area. This reaction resembles an allergic reaction and is temporary. It is not an actual tumor growth or a change in malignancy.
Recommendation
If a mast cell tumor is suspected, palpation should be performed carefully. It is advisable to have antihistamines or corticosteroids readily available and to avoid unnecessary manipulation. However, an accurate diagnosis is essential for further treatment.
Myth 2: Taking a sample will "activate" and "spread" a tumor.„
The concerns of pet owners
Another common misconception is that taking tissue samples for cytological or histological examination could "annoy" the tumor and lead to the spread of tumor cells.
The facts
A tumor does not behave like a plant that spreads its seeds when touched. The sampling procedure leads to... not This could lead to tumor cells actively spreading throughout the body. This concern is unfounded and should not prevent necessary diagnostic procedures.
Tumor cell seeding in the puncture tract
There is a minimal risk that tumor cells may be mechanically displaced along the puncture tract, a phenomenon known as Tumor cell seeding This is referred to as a "puncture wound." This risk is extremely low, and the probability of a new tumor developing from it is minimal. In oncological surgery, the puncture tract is removed as a precaution during tumor removal to further reduce this risk.
Caution when puncturing abdominal tumors
When puncturing tumors in the abdominal cavity, there is a slightly higher risk of spreading tumor cells into the abdominal cavity. Although such cases are extremely rare, pet owners should be informed of this risk and the decision to perform a puncture should be carefully considered.
Recommendation
Sample collection is an essential step for accurate diagnosis and effective treatment. The benefits far outweigh the minimal risks. Open communication with pet owners is crucial in this process.
Myth 3: Tumors can be caused by stress or trauma.
The concerns of pet owners
Some pet owners believe that stress or physical trauma can lead to the development of tumors in their animals. For example, it is assumed that a bump or injury can cause a tumor.
The facts
There are no scientific evidence This does not support the notion that stress or physical trauma directly leads to the development of tumors in animals. Tumor formation is a complex process influenced by genetic factors, environmental influences, and sometimes unknown causes. A single event such as a bump or injury is generally not the trigger for tumor formation.
Recommendation
It is important to take injuries in animals seriously and have them checked by a veterinarian if necessary. However, pet owners should rest assured that such incidents do not lead to tumors.
Myth 4: Tumors are always fatal
Many people believe that a tumor diagnosis is inevitably a death sentence, especially for pets. However, this is a widespread misconception. Not all tumors are malignant., and many tumors grow slowly or even show no negative effects on the animal's well-being. Benign tumors For example, they grow locally and do not metastasize. They can often be surgically removed without the risk of recurrence or worsening of the condition.
Even at malignant tumors Today there are many treatment options that can significantly improve the prognosis. Through a Early detection And early, individually tailored therapy can often increase the chances of a complete cure or at least a significant extension of lifespan.
Thanks to modern diagnostic techniques such as imaging procedures or biopsies, veterinarians can detect tumors at an early stage, before they spread throughout the body. Therapeutic options are also increasingly available – from Surgery above radiotherapy up to targeted therapies – have developed enormously. Many animals that receive successful tumor treatment can many happy years Live a full life and enjoy a high quality of life. A tumor diagnosis does not necessarily have to mean the end, but also opens up opportunities if action is taken in time.
Myth 5: Chemotherapy is too stressful for animals
The thought of chemotherapy is frightening for many pet owners, as it is associated with drastic side effects known from human medicine. But the Chemotherapy in animals This differs considerably from the treatment of animals in humans. While aggressive treatment approaches are often pursued in human patients to prolong life at all costs, the focus in animals is usually on... Maintaining quality of life The focus is on the animal's well-being. Veterinarians specifically adjust the doses and treatment regimens to minimize side effects and ensure that the animal tolerates the therapy well.
Actually tolerate Most animals respond surprisingly well to chemotherapy.. Severe side effects such as nausea, vomiting, or hair loss, which are known in humans, occur less frequently and often less severely in animals. Should side effects occur, there are now many supportive therapies that can alleviate these symptoms. Side effect profiles Chemotherapy in animals is often milder because the goal is not to administer maximum doses, but to find a balance between efficacy and well-being. Many animals lead almost normal lives during chemotherapy and enjoy their time with their families. Therefore, fear of chemotherapy should not lead to avoiding potentially life-saving treatment.
Myth 6: Natural remedies can cure tumors
Natural remedies are enjoying increasing popularity, including in veterinary medicine. Some pet owners are convinced that alternative or natural therapies Tumors can be cured without resorting to conventional medical interventions such as surgery, chemotherapy, or radiation. However, this view is based on Misinformation, since it has so far no scientific evidence There is evidence that natural remedies can effectively fight or cure tumors.
While certain natural remedies While these remedies can certainly help support an animal's overall well-being, for example by strengthening the immune system or alleviating symptoms, they do not replace evidence-based medical treatment. Tumors are generally complex conditions that require careful management. targeted medical therapies require.
Foregoing conventional treatments in favor of alternative approaches can drastically reduce the chances of a cure and even accelerate the progression of the disease. Pet owners should always remember that the use of natural remedies in combination with conventional medical therapy should be done under the guidance of an experienced veterinarian to achieve the best possible outcome for the animal. Evidence-based medicine This remains the basis for successful tumor treatment, and natural remedies should at best be considered as a supplementary support, not as a primary treatment method.
Factors that promote tumor growth
Tumor growth is influenced by a multitude of factors, both internal and external. Among the most important internal factors is... Genetics. Certain genetic mutations or inherited predispositions can significantly increase the risk of developing tumors. This also applies to... Immune system plays a central role:
A healthy immune system recognizes and fights abnormal cells, while a weakened immune system may be unable to effectively eliminate tumor cells, which can lead to their uncontrolled growth. Another crucial factor is the Blood supply of the tumor. Tumors require a constant supply of nutrients and oxygen, which is ensured by the formation of new blood vessels (angiogenesis). Without an adequate supply, tumor cells cannot survive or continue to divide.
An additional factor is the Cell cycle, that is, the process of cell division. Tumor cells often go through the cell cycle faster than healthy cells, leading to accelerated growth. Furthermore, they also affect hormonal changes In some types of tumors, such as breast or prostate cancer, growth is significantly accelerated because hormones like estrogen or testosterone act as growth signals for the tumor cells. Finally, other factors also play a role. Environmental influences Long-term exposure to carcinogenic substances such as chemicals, radiation, or environmental toxins can promote the development and growth of tumors. Each of these factors contributes to tumor formation and growth in different ways, which is why understanding these influences is crucial in cancer research and treatment.
Factors that influence tumor growth
Hereditary factors that influence tumor growth.
The availability of blood vessels to supply nutrients to the tumor.
The body's immune system and its ability to fight tumor cells.
The speed at which tumor cells divide and multiply.
External factors such as chemicals, radiation, and environmental toxins.
The influence of hormones on the growth of certain types of tumors.
Frequently asked questions about oncology in veterinary medicine
What are the first signs of a tumor in pets, and when should you consult a veterinarian?
The signs of a tumor in pets can vary greatly and depend heavily on the type of tumor and the affected area of the body. Often, pet owners notice a unusual swelling or lumps under the skin, which can enlarge over time. These lumps are not always painful and are often discovered accidentally while stroking. Other possible symptoms are weight loss, Loss of appetite, lethargy or changes in the animal's behavior. Tumors in the gastrointestinal tract can lead to... Vomiting, Diarrhea or constipation may occur. Tumors in the airways can also cause this. Cough or Breathing difficulties appear.
It is advisable to consult a veterinarian at the first sign of any unusual swelling or change in behavior, especially if the symptoms persist for more than a week or worsen. early diagnosis This is crucial, as it expands treatment options and significantly improves the chances of success. Even small, seemingly harmless lumps should not be ignored, as they can sometimes indicate a more serious condition. The veterinarian can use various diagnostic methods such as... Biopsies, Blood tests and imaging procedures Ultrasound or X-rays are used to determine whether a tumor is benign or malignant. The earlier the diagnosis is made, the better the chances of successful treatment.
How is a tumor diagnosed, and what examinations are necessary?
Diagnosing a tumor usually requires a combination of several examinations, tailored to the veterinarian's suspicions and the animal's symptoms. First, the veterinarian will conduct a thorough examination. clinical examination This involves palpating the animal for external swellings, lumps, or other unusual changes. If a tumor is suspected, the veterinarian will usually perform a Fine needle aspiration or biopsy We recommend this procedure. Fine-needle aspiration involves taking a small amount of cells from the suspicious mass, which are then examined under a microscope. This method is minimally invasive and often allows for an initial assessment of whether the tumor is benign or malignant.
At a biopsy A larger piece of tissue is taken from the tumor, allowing for a more precise histopathological examination. Furthermore, Blood tests These examinations are performed to check the animal's general health and to determine whether the tumor has already affected other organs or systems in the body. In many cases, they are also imaging procedures How Ultrasound, X-ray or CT/MRI used to determine the exact location, size, and extent of the tumor. This is particularly important to determine whether the tumor can be surgically removed and whether it has already spread. Metastases (Maiden tumors) may have formed in other organs. By combining these examinations, the veterinarian can make a sound diagnosis and develop the best treatment strategy.
What treatment options are available for pets with a tumor, and how is the decision made?
The treatment of a tumor in pets depends on several factors, including the Type of tumor, be Location, his Size, Whether it is malignant or benign, and whether it has spread to other organs (metastasis). The most common treatment options include: Surgery, chemotherapy, radiotherapy and newer approaches such as targeted therapies or Immunotherapies.
The Surgery Surgery is often the first choice, especially for localized tumors. The goal is to remove the tumor completely, often including surrounding tissue to ensure no cancer cells remain. For benign tumors, surgery can often result in a complete cure. For malignant tumors, surgery can help reduce the tumor mass and alleviate symptoms.
chemotherapy It is frequently used for tumors that have already spread to other parts of the body or for tumor types that respond to medication, such as Lymphomas. The treatment aims to destroy cancer cells or slow their growth while maintaining the animal's quality of life. radiotherapy It can also be used, particularly for tumors that cannot be completely removed surgically or that grow in hard-to-reach places. More recently, targeted therapies and Immunotherapies have gained importance, which specifically target the properties of tumor cells and stimulate the animal's immune system to fight the tumor.
The decision for a particular treatment depends on many factors, and the veterinarian will work closely with the owners to develop the best treatment plan. This includes not only the chances of success, but also the Quality of life and the animal's well-being plays a crucial role. The veterinarian will fully inform the owners about the risks, side effects, and the expected course of treatment.
What are the most common side effects of cancer treatment, and how can they be minimized?
The side effects of cancer treatment depend on the chosen therapy. In the case of a operation Post-operative complications such as Swelling, Pain, Infections Or, in rare cases, bleeding may occur. Pain relievers and anti-inflammatory medications are usually administered to aid recovery. Many animals recover well after surgery and can resume a normal life within a few days or weeks.
At the chemotherapy The side effects are often less severe than in humans, as the dosage for animals is adjusted to minimize the impact on their quality of life. The most common side effects include: Loss of appetite, mild nausea, Diarrhea and in rare cases hair loss. Many of these symptoms are temporary and can be treated with supportive measures such as Dietary adjustments or Medication The animal will be treated well. The veterinarian will plan the therapy so that the animal receives the best possible care and side effects are minimized.
The radiotherapy It can cause skin irritation at the treated area, but this usually subsides after the treatment is completed. In some cases, fatigue may also occur, but this is usually temporary. Modern radiation therapy techniques make it possible to irradiate the tumor precisely, while largely sparing the surrounding healthy tissue.
Overall, it is true that the Monitoring the animal Close monitoring is crucial during treatment to detect and treat side effects early. Veterinarians maintain close contact with owners to ensure the animal receives the best possible support throughout the entire therapy.
What are the chances of recovery from a tumor, and what are the crucial factors for successful treatment?
The Chances of recovery The prognosis for a tumor depends on many factors, including the type of tumor, its stage at diagnosis, and the chosen treatment. Benign tumors can often be completely cured by surgery without the need for further therapy. For malignant tumors, the prognosis depends heavily on the type of tumor and the stage of the disease. Early detection Early diagnosis is one of the most important factors influencing the chances of recovery. Tumors diagnosed at an early stage are often easier to treat and have a higher probability of being cured or controlled long-term.
Another crucial factor is the localization of the tumor. Tumors located in areas that are easily accessible and operable often have a better prognosis. Also, the Presence of metastases plays a major role. Tumors that have already spread to other organs are more difficult to treat, but in many cases a combination of Surgery, chemotherapy and radiotherapy to help control the disease and maintain the animal's quality of life.
Modern treatment approaches such as Immunotherapies and targeted therapies These treatments have improved the survival chances of many animals in recent years. They aim to strengthen the immune system or specifically attack tumor cells without damaging healthy tissue. In many cases, such therapies lead to a long-term control of the tumor, Even if a complete cure is not possible, close cooperation between the veterinarian and the owners is crucial for success to ensure the animal receives the best possible treatment.
