Maltese cancer risks, early tumor symptoms in Maltese dogs, common cancers in this breed are topics many owners don’t think about until their dog is already a senior. Yet understanding how this small, long-lived breed ages—and what warning signs to watch for—can make a real difference in quality of life and early detection.

A. Breed Overview: The Maltese in a Health Context
The Maltese is a toy breed known for its silky white coat, affectionate nature, and surprisingly bold personality. Typically weighing 4–7 pounds and living 12–15 years or more, they are often described as lively, devoted, and people-oriented companions.
Key characteristics that matter for health and cancer risk:
– Rozmiar: Toy breed, long lifespan, which means more years for age-related diseases (including tumors) to develop.
– Coat and color: Pure white coat and often pink or lightly pigmented skin can contribute to sensitivity to sun exposure.
– Temperament & lifestyle: Usually indoor dogs, often carried or walked on leash; this can lower some injury risks but doesn’t eliminate health issues.
Maltese are not among the very highest-risk breeds for cancer overall, but studies and clinical experience suggest they may be more prone to:
– Mammary (breast) tumors, especially in intact females
– Certain skin and oral tumors
– Age-related cancers due to their long lifespan
Knowing these tendencies allows owners to be more proactive with screening and senior care.

B. Tumor and Cancer Risks for the Maltese
While any dog can develop cancer, some patterns appear more often in this breed. Below are several of the more commonly noted tumor types in Maltese, along with simple explanations of risk factors.
1. Mammary (Breast) Tumors
In small-breed, intact female dogs, mammary tumors are very common, and the Maltese is no exception.
– Who’s at risk: Females that were never spayed, or spayed later in life.
– Why: Hormone exposure over many heat cycles can stimulate mammary tissue growth and abnormal cell changes.
– What owners may notice: Firm or soft nodules along the “chain” of mammary glands (from chest to groin), sometimes single, sometimes multiple.
Early spaying greatly reduces the risk of mammary tumors, but it does not completely eliminate it if done later. Any new lump near the nipples should be checked promptly.
2. Skin Tumors (Benign and Malignant)
Maltese have pale skin under their white coat, which can be more sensitive to UV light, especially on:
– Nose
– Ears
– Belly (if hair is thin)
– Areas where hair is clipped short
Common skin tumors in small breeds can include:
– Guzy komórek tucznych
– Soft tissue sarcomas
– Benign growths such as lipomas (fatty tumors) or sebaceous adenomas
While many skin lumps are harmless, some are not. Because this breed is often groomed regularly, owners are in a good position to spot changes on the skin early.
3. Oral Tumors
Some reports suggest small breeds, including Maltese, may be overrepresented in certain oral cancers such as oral melanoma or other mouth tumors.
– Risk factors: Chronic dental disease, inflammation, and age may play a role.
– Possible signs: Bad breath that worsens, bleeding from the mouth, visible masses on the gums, or difficulty eating.
Since Maltese are predisposed to dental problems generally, regular mouth checks are especially important.
4. Lymphoma
Lymphoma is a common cancer in dogs of many breeds, and Maltese are no exception.
– What it is: A cancer of lymphocytes, a type of white blood cell.
– Where it can show up: Lymph nodes, spleen, liver, or other organs.
– Owner-visible signs: Swollen lymph nodes under the jaw, in front of the shoulders, or behind the knees, plus lethargy, weight loss, or decreased appetite.
5. Urinary and Other Age-Related Tumors
Older Maltese can also develop tumors in the bladder, liver, spleen, or other organs, simply as a result of aging and cell wear-and-tear over time. These may not be breed-specific, but the Maltese’ long lifespan means owners are relatively more likely to face age-related tumors at some point.

C. Early Warning Signs Owners Should Watch For
Early tumor symptoms in Maltese dogs can be subtle at first. Because they are small and often carried or doted on, small changes may be overlooked or mistaken for “getting older.”
1. Lumps, Bumps, and Skin Changes
Check your Maltese regularly during grooming or cuddling:
– Run your hands gently over the entire body once a month.
– Feel along the mammary chain in females.
– Look at the skin on the ears, nose, and belly for:
– New dark or red spots
– Scabs or sores that don’t heal
– Thickened or crusty areas
When to call your vet:
– Any lump that is new, growing, changing, painful, or ulcerated
– Any sore or scab that does not heal within 2–3 weeks
2. Weight, Appetite, and Energy Changes
Because Maltese are small, even small changes can be meaningful:
– Unintentional weight loss
– Decreased appetite or pickiness that is new
– Lethargy, sleeping more, or reluctance to play or walk
– Panting more or seeming uncomfortable at rest
Sudden or steady changes over a few weeks warrant a veterinary visit, especially in a dog over 7–8 years old.
3. Mobility, Pain, and Behavior
Tumors affecting bones, nerves, or internal organs can cause:
– Lameness or limping
– Difficulty jumping onto furniture
– Stiffness when getting up
– Hiding, irritability, or not wanting to be touched in certain areas
Any persistent pain or mobility issue should be evaluated.
4. Bleeding, Coughing, and Other Red Flags
Watch for:
– Bleeding from the mouth, nose, or rectum
– Persistent cough or trouble breathing
– Straining to urinate or blood in the urine
– Vomiting or diarrhea that keeps recurring
These signs do not mean a dog definitely has cancer, but they do indicate a need for timely veterinary assessment.

D. Senior Care Considerations for the Maltese
As Maltese age, their risk for tumors and other chronic conditions naturally increases. Thoughtful senior care can help detect problems earlier and keep them comfortable.
1. How Aging Affects Maltese
Typical aging changes include:
– Slower metabolism and tendency to gain weight if diet is not adjusted
– More fragile joints and possible arthritis
– Declining organ function (kidneys, liver, heart)
– Weaker immune system and slower healing
Because cancer is largely a disease of older cells, these age-related shifts can overlap with increased tumor risk.
2. Nutrition and Body Condition
For senior Maltese (often starting around 8–10 years):
– Aim for a slim but not skinny body condition; you should feel ribs easily but not see them sharply.
– Use a senior-appropriate diet recommended by your veterinarian, taking into account:
– Weight management
– Dental health
– Any kidney, liver, or heart issues
Avoid crash diets. If weight loss is unintentional, this is a reason for a check-up, not just a feeding change.
3. Exercise and Activity Adjustments
Gentle, consistent activity supports joint health, digestion, and mood:
– Daily short walks
– Light play sessions on non-slippery surfaces
– Avoiding high-impact jumps from beds or sofas (use steps or ramps instead)
Monitor for coughing, heavy panting, or limping and discuss these with your veterinarian.
4. Joint Care and Pain Management
Senior Maltese may show subtle pain:
– Hesitation before climbing stairs
– Reluctance to jump
– Seeming “grumpy” when picked up
Discuss options such as:
– Environmental changes (ramps, rugs, soft bedding)
– Veterinary-approved pain management strategies
– Possible joint-support supplements, only under veterinary guidance
5. Check-Up Intervals and Screening
For a healthy adult Maltese, annual exams are typical. Once they become seniors:
– Consider twice-yearly wellness visits, particularly after age 8–10.
– Ask about routine screening such as:
– Bloodwork and urinalysis
– Dental evaluations
– Imaging (X-rays or ultrasound) when indicated
These visits create a baseline, so small changes are easier to spot and investigate early.

E. General Tumor Prevention & Wellness Support
No strategy can guarantee that a Maltese will never develop cancer, but you can lower some risks and support overall resilience.
1. Maintain a Healthy Weight
Excess body fat is linked to inflammation and may increase the risk or severity of various diseases.
– Use a measuring cup for food.
– Limit high-calorie treats.
– Ask your vet for your dog’s ideal weight range and how to achieve it safely.
2. Diet and Hydration
Aim for:
– A complete and balanced diet appropriate for size, age, and health status.
– Fresh water available at all times.
– Avoiding frequent high-fat table scraps, which can upset the pancreas and add unnecessary calories.
Some owners explore foods rich in antioxidants or omega-3 fatty acids. While these may support general health, they should not be viewed as cancer treatments. Always discuss diet changes and supplements with your veterinarian.
3. Regular Physical Activity
Movement supports:
– Cardiovascular health
– Digestive function
– Muscle mass and joint function
– Mental well-being
Even 2–3 short walks plus gentle play each day can be enough for many Maltese, adjusted to your dog’s abilities.
4. Sun and Environmental Exposure
Because of their pale skin:
– Avoid prolonged midday sun, especially for dogs with thin coats or shaved areas.
– Use shaded areas and limit time on hot surfaces.
– Talk to your vet before using any pet-safe sunscreen on sensitive areas like the nose and ears.
Minimize exposure to:
– Secondhand smoke
– Harsh lawn chemicals and strong household cleaners
– Unnecessary pesticides in the yard
These measures may reduce overall toxic burden, although they cannot guarantee prevention.
5. Thoughtful Use of Supplements
Common interest areas include:
– Joint-support supplements
– General wellness blends
– Herbal or “immune-support” products
These should be:
– Selected with veterinary guidance
– Checked for safety, dosing for toy breeds, and interactions with any medications
No supplement should be used in place of diagnostic work-ups or conventional treatments recommended by your veterinarian.

F. Integrative and Holistic Support (As a Complement Only)
Some families consider integrative approaches to help their Maltese feel as well as possible during cancer treatment or in senior years. These might include:
– Gentle akupunktura to support comfort and mobility
– Massage or physical therapy for stiffness and muscle maintenance
– Carefully chosen herbal or nutritional support, under a veterinarian trained in integrative medicine
The goal of these approaches is to:
– Support overall vitality
– Help manage stress and discomfort
– Complement, not replace, modern diagnostics and oncology care
If you are interested in integrative options, look for a veterinarian with additional training in this area and always coordinate care with your primary vet or veterinary oncologist.
