When to go to veterinary oncology?

Veterinary oncology allows to diagnose, monitor and treat tumour processes with a focus on the pet's quality of life.

Suspicious lumps, masses or lesions

The appearance of lumps or visible changes requires veterinary assessment to determine their nature.

  • Cutaneous or subcutaneous masses

  • Lesions that grow or change in appearance

  • Nodules detected at check-ups

Oncological diagnosis and assessment

When a tumour process is suspected or confirmed, oncology allows us to assess options and plan the most appropriate approach.

  • Diagnostic confirmation by testing

  • Assessment of therapeutic options

  • Coordination with surgery or other specialties

Oncological follow-up and clinical monitoring

Monitoring allows to control the evolution of the process and to prioritise the welfare of the pet at each stage.

  • Control of the disease over time

  • Pain management and associated symptoms

  • Accompanying the guardian and the patient

What should you do following a cancer diagnosis in dogs or cats?

Receiving a cancer diagnosis can raise many questions. The next step is to gather the necessary information to understand what type of tumour your pet has, how it might progress, and what treatment options are available.

Not all tumours progress in the same way, nor do they all require the same treatment. For this reason, each case must be assessed on an individual basis, taking into account the diagnosis, the extent of the disease, the patient’s general condition and the family’s priorities.

Confirm what type of tumour it is

Finding a lump or mass does not always reveal its nature. To guide or confirm the diagnosis, it may be necessary to analyse a sample using a veterinary cytology or a biopsy.

Cytology involves examining cells taken from the lesion and can provide an initial indication in many cases. A biopsy allows a sample of tissue to be analysed and can provide more comprehensive information about the type of tumour and its characteristics.

Depending on the result, the team will explain to you:

  • What type of injury has been identified?

  • Whether it is considered benign or malignant.

  • If further tests are required.

  • What behaviour can be expected?

  • What treatment options might be considered?

  • It is not yet possible to determine what information this is.

In some cases, the tumour grade is also assessed; this describes certain microscopic characteristics relating to its likely behaviour.

Assess whether the disease is localised or has spread

Once a tumour has been confirmed, it may be advisable to carry out an extent or staging assessment. The aim is to determine the size and location of the tumour, check whether it has affected nearby structures, and look for any signs of spread.

Depending on the type of tumour, this investigation may include:

  • Blood tests to assess general health, detect abnormalities and check the functioning of various organs.

  • Urinalysis to complement the renal and urinary assessment.

  • Veterinary X-rays to examine the chest, abdomen or specific bony structures.

  • Veterinary ultrasound to examine abdominal organs, lymph nodes and any internal masses.

  • Veterinary CAT scan when it is necessary to determine the extent of an injury more precisely or to plan a procedure.

  • Cytology or biopsy of lymph nodes and other tissues where indicated.

Not all patients need all of these tests. They are selected based on the type of tumour, its location and the information that each procedure can provide.

Define the treatment objective

The aim may vary depending on the diagnosis and the patient’s condition. Before starting, it is important to understand whether the treatment is intended to:

  • Remove the tumour completely where possible.

  • To control or slow the progression of the disease.

  • To reduce the size of a dough.

  • To prevent or relieve certain symptoms.

  • To maintain comfort and quality of life.

  • Combine several of these options.

The plan may include surgery, medical treatment, supportive care or palliative care. Some pets need a single procedure, whilst others require follow-up appointments or treatment over a longer period.

If an operation is planned, the case can be co-ordinated with the services of veterinary surgery o soft tissue surgery.

Before the procedure, the team at veterinary anaesthesia and analgesia adapts the protocol to the patient’s clinical condition and needs.

Questions you can ask during the consultation

To make an informed decision, it may be helpful to ask:

  • Has the type of tumour been confirmed?

  • Is a biopsy or any further tests required?

  • Does the condition appear to be localised or has it spread?

  • What is the aim of each option?

  • What benefits can be expected?

  • What risks or adverse effects might occur?

  • How might the treatment affect your daily life?

  • How many appointments and check-ups will be needed?

  • What would happen if we decided not to undergo a specific treatment?

  • Are there any options that focus solely on comfort?

  • What signs should we look out for at home?

  • When should the next service be carried out?

Booking an oncology consultation does not oblige you to start a specific course of treatment. Its purpose is to understand your situation, clarify any doubts and compare the available options.

Monitoring quality of life at home

During treatment or follow-up, look out for any changes in:

  • Appetite and water intake.

  • Weight and muscle mass.

  • An active lifestyle and a desire to socialise.

  • Mobility and the ability to rest.

  • Breathing.

  • Vomiting or diarrhoea.

  • Pain or discomfort.

  • Appearance and size of the lesion.

  • Tolerance to medication.

  • Number of good days and days when symptoms were more severe.

Making a note of this information or recording videos can help you assess your pet’s progress between appointments. Do not change the doses or stop treatment without first discussing it with the veterinary team.

If symptoms persist, we can arrange a follow-up appointment with the Benivet Benissa Pain Clinic.

If your appetite decreases, you lose weight or find it difficult to maintain an appropriate body condition, it may be advisable to have an assessment of veterinary nutrition.

In patients with other medical conditions or undergoing long-term treatment, monitoring can also be integrated with veterinary internal medicine.

When should you contact the clinic?

Please contact the team if your pet shows any of the following symptoms:

  • Difficulty breathing.

  • Severe weakness or loss of consciousness.

  • Pain that does not appear to be under control.

  • Repeated vomiting or diarrhoea.

  • Persistent refusal to eat or drink.

  • Bleeding.

  • Fever, shivering or severe fatigue.

  • Inflammation or problems with a surgical wound.

  • Adverse effects following administration of the medication.

  • A sudden deterioration in his general condition.

Some patients may require treatment or monitoring in our veterinary hospitalisation.

Second opinions and referred cases

If your pet has already been treated at another clinic, please bring any reports, cytology or biopsy results, laboratory tests, imaging scans and details of previous treatments. Reviewing all this documentation helps us to understand the case better and avoid unnecessary repeat tests.

Veterinary professionals can also submit the documentation via the Case studies from Benivet Benissa.

Estamos muy agradecidos con el equipo de Benivet Benissa por la atención y el cuidado que han tenido con nuestro perro. Llegamos a la clínica después de varias semanas de problemas en la piel y de haber probado diferentes tratamientos sin conseguir una mejoría real. Nuestro Yorkshire, que ya tiene 14 años, tenía heridas, zonas muy inflamadas y pérdida de pelo. En Benivet realizaron las pruebas necesarias y finalmente encontraron la causa: una demodicosis grave con una infección bacteriana secundaria. Nos explicaron todo con mucha claridad y empezamos un tratamiento específico. Aunque el tratamiento todavía no ha terminado, la mejoría ha sido enorme: las heridas han desaparecido, la piel está mucho mejor, las zonas oscuras de las patas están desapareciendo y el pelo ya está empezando a crecer de nuevo. En la última revisión todavía quedaban algunas bacterias, por lo que nos han prolongado el tratamiento una semana más. Queremos agradecer especialmente la profesionalidad, la atención y la paciencia que han tenido con nosotros y con nuestro pequeño. Después de todo lo que habíamos pasado, por fin sentimos que nuestro perro está en buenas manos. ❤️ Muchas gracias a todo el equipo de Benivet Benissa. 🐶❤️

Durante los últimos dos meses hemos vivido momentos muy difíciles y llenos de incertidumbre. Nuestro galgo macho de 5 años se rompió una pata y además tenía un tumor. Para resumir una historia bastante larga: afortunadamente resultó no ser cáncer, pero finalmente tuvieron que amputarle la pata y ha pasado por momentos de mucho dolor. Estamos enormemente impresionados y agradecidos con todo el personal de esta clínica. Tanto el equipo de veterinarios como el personal de apoyo se comunican perfectamente, son muy empáticos y atentos, pero al mismo tiempo proactivos y tremendamente profesionales. Sinceramente, no tenemos ni un solo punto de crítica. Estamos simplemente muy felices de haber llegado a esta clínica y, sin ninguna duda, a partir de ahora serán nuestros veterinarios de confianza. **Gracias por todo, querido equipo de la Clínica Veterinaria Benivet.** ❤️ Willem y Javi

Fuimos el viernes por la tarde porque nuestro gato se comió un hilo largo. Las veterinarias fueron súper pacientes a pesar de que el gato se puso peleón por el miedo. Le hicieron ecografía y luego lo metieron a cirugía casi inmediatamente. El cirujano fue excelente, nos explicó todo el procedimiento y nos avisó por WhatsApp cuando estuvo listo el gatito, se quedó en observación y al día siguiente lo hemos recogido. La operación fue impecable y el gatito está en casa, la sutura está perfecta. Fueron excepcionales.

Lleve a mi gato de 6 años de urgencia porque se había tragado un hilo largo y gordito, y por la mañana vomitó un trozo. Menos mal que lo hice ya que al día siguiente era festivo, y haber esperado más habría resultado seguramente en necrosis y perforaciones intestinales. Mi gatito fue muy bien atendido por todos los veterinarios. Lo sedaron porque estaba nervioso, le hicieron ecografía para encontrar el hilo en el yeyuno, ya medio plegado, y lo operaron. Fue caro pero lo pagaría de nuevo, porque la vida de mi gatito no tiene precio y lo atendieron aún cuando iban a empezar después de su hora de cierre. Además está mañana al recogerlo estaba bien, tranquilo y dolorido, y la sutura se ve super limpia y bien hecha. Mis agradecimientos a Constantino y al resto de veterinarias que atendieron a mi gato.

No tenemos más que agradecimiento para todo el equipo de Benivet Benissa. Llevamos a nuestro perro Dachs para una cirugía de columna delicada —una hernia que le comprimía la médula— y desde el primer minuto nos transmitieron una tranquilidad enorme. Incluso nos avisaron de la dirección exacta para no confundirnos con otra clínica que hay a pocos metros: un detalle pequeño que ya dice mucho de cómo trabajan. Queremos destacar especialmente a dos personas. Al traumólogo, Constantino, que hizo un trabajo impecable: retiró toda la hernia y liberó la médula sin complicaciones. Y a la anestesista, Ana, que cuidó cada detalle —algo nada menor en una intervención así—. Gracias a ambos, en las primeras 24 horas Dachs ya recuperaba movilidad voluntaria en la pata. Cuando surgió un pequeño imprevisto con la sonda, lo resolvieron al momento y con total profesionalidad. Pero si algo destaca por encima de lo médico es el trato humano de todo el equipo. Nos mantuvieron informados con mensajes constantes y cercanos, nos escribían para contarnos que Dachs "se portaba muy bien", que nos deseaba buenas noches, e incluso se adelantaron ofreciéndonos un arnés de apoyo por si lo necesitaba. Se nota que aquí no solo tratan a los animales: los cuidan de verdad. Gracias de corazón a Constantino, a Ana y a todo el equipo de Benivet.

How we approach an oncology case and what tests may be indicated

The veterinary oncology is indicated when a bulgeA lesion that grows or does not resolve, weight loss without a clear cause, abnormal bleeding, persistent apathy or test results that suggest a tumour process. At Benivet Benissa we start with a complete assessment and, if it is necessary to confirm the diagnosis or plan the treatment, we recommend the following tests only when they provide useful information:

Veterinary practice in BenissaClinical history, complete examination and prioritisation of the diagnostic plan.

Microscopy and cytologyFirst quick approach to orientate the type of lesion in many lumps/masses and decide on the next step.

Blood tests y urinalysisto assess general condition, liver/kidney function, anaemia/inflammation and safety if sedation, surgery or treatments are considered.

Veterinary ultrasounduseful to study the abdomen (organs, lymph nodes, masses, fluid) and to orientate the extension of the process.

Veterinary radiologyIn some cases, to assess bone involvement or to monitor progress.

Veterinary CAT scanrecommended when we need a more detailed study to staging o precise planning (complex areas, surgery, deep structures).

If intervention is proposed, we coordinate the case with veterinary surgery and the protocol of anaesthesia and analgesia for a safe procedure and good pain control. If the patient needs intensive monitoring or treatment, we can rely on veterinary hospitalisation. And if there are co-morbidities or long-term follow-up, we integrate it with veterinary internal medicine.

Where we are

Frequently asked questions about our veterinary oncology service

Some warning signs are lumps that increase in sizeThe most common symptoms include weight loss, weight loss, non-healing wounds, bleeding, persistent coughing, changes in appetite, recurrent vomiting, lameness or prolonged decay. However, many tumours do not produce symptoms in the early stages, so veterinary check-ups are key to early detection.

Depending on the case, this may include:

  • Cytology and biopsy

  • Ultrasound and digital radiography

  • TAC to assess extent and plan surgery

  • Full analytics

  • Specific tests according to organ affected
    The aim is to obtain an accurate diagnosis and appropriate staging in order to choose the best treatment.

No. In veterinary medicine, the priority focus is on the animal welfare. We adjust doses, drugs and protocols to minimise side effects. Many patients tolerate chemotherapy very well and maintain a good quality of life during treatment.

Depending on the type of tumour, options may include:

  • Oncological surgery

  • Chemotherapy

  • Immunomodulatory treatments

  • Pain management and palliative care
    At Benivet Benissa we design an individualised plan, always evaluating risks, benefits and prognosis.

The prognosis varies depending on the type of tumour, location, rapidity of growth and early detection. Some tumours are curable with surgery; others can be controlled for months or years with combined treatments. We assess each case with clarity and transparency, without raising false expectations.

Some keys are: maintaining good nutrition, controlling pain, ensuring adequate rest, monitoring changes in appetite and energy, following medication as prescribed and attending check-ups. The joint work between guardian and veterinarian is fundamental for the wellbeing of the oncology patient.
