Can Snakes Get Cancer? [Signs And Symptoms]
Yes, Snakes Can Get Cancer
Cancer is not just a disease that affects humans, dogs, and cats. Snakes and other reptiles can develop cancer too. While it is not as commonly discussed or diagnosed in snakes as it is in mammals, tumors and cancerous growths do occur in captive and wild snakes. Understanding what to look for and when to seek help can make a real difference in your snake’s outcome.
The study of cancer in reptiles is still an evolving field, and veterinary knowledge has improved significantly in recent years. More reptile owners are seeking veterinary care for their pets, which means more cases are being identified and studied.
Types of Cancer Found in Snakes
Snakes can develop several types of cancer, both benign (non spreading) and malignant (cancerous and potentially spreading). Some of the most commonly reported types include lymphoma, which affects the lymphatic system, squamous cell carcinoma, which affects the skin and scales, and fibrosarcoma, which develops in connective tissue.
Internal tumors affecting the liver, kidneys, and reproductive organs have also been documented. These are harder to detect because they develop inside the body where you cannot see them. By the time symptoms appear, internal tumors may already be advanced.
Benign tumors are more common than malignant ones in snakes. These growths may cause problems if they are in a location that interferes with eating, breathing, or movement, but they do not spread to other parts of the body the way cancerous tumors do.
Signs and Symptoms to Watch For
Visible lumps or bumps under the skin are the most obvious sign of a potential tumor. These may appear as firm swellings along the body, on the head, or near the tail. Not every lump is cancer though. Abscesses, retained shed, and other conditions can also cause visible swelling.
Other signs that may indicate cancer include unexplained weight loss, loss of appetite, difficulty swallowing, changes in behavior or activity level, and unusual growths in or around the mouth. Some snakes with internal tumors may develop a swollen abdomen or difficulty passing waste.
Skin changes can also be a warning sign. Discolored patches, sores that do not heal, or abnormal scale growth could potentially indicate skin cancer or other growths. If you notice anything unusual about your snake’s appearance or behavior, it is worth getting it checked by a veterinarian.
What Causes Cancer in Snakes?
The exact causes of cancer in snakes are not fully understood, but several factors are believed to play a role. Genetics likely contribute, as some lineages may be more prone to certain types of tumors. Age is another factor, as older snakes are more likely to develop cancer than younger ones, just like in mammals.
Environmental factors may also contribute. Long term exposure to UVB lighting, certain substrates, or chemical cleaning agents has been discussed as a potential risk factor, though research in this area is limited. Some viral infections in reptiles have also been linked to tumor development.
Stress and poor husbandry may weaken the immune system over time, making snakes more susceptible to abnormal cell growth. While we cannot say definitively that bad husbandry causes cancer, maintaining proper care conditions supports overall immune health, which may help the body fight off abnormal cells before they become tumors.
Diagnosis and Treatment
If you suspect your snake has a tumor, the first step is a veterinary examination. A reptile vet can perform a physical exam and may recommend additional diagnostics like X rays, ultrasound, or a biopsy to determine what the growth is and whether it is cancerous.
Treatment options for cancer in snakes are more limited than they are for mammals, but they do exist. Surgical removal is the most common treatment for accessible tumors and can be very successful for benign growths and early stage cancers that have not spread. Some veterinary oncologists have also used chemotherapy and radiation therapy on reptiles with varying degrees of success.
The prognosis depends heavily on the type of cancer, its location, and how early it was caught. Some snakes do very well after tumor removal and live normal lives afterward. Others may have more aggressive cancers that are difficult to treat. Your veterinarian can help you understand the options and make the best decision for your pet.
When to See a Vet
Any lump, bump, or unusual growth on your snake warrants a veterinary visit. The sooner a potential tumor is evaluated, the better the chances of successful treatment. Do not wait to see if it goes away on its own, because cancerous tumors typically do not resolve without intervention.
Changes in appetite, weight loss, difficulty moving, and behavioral changes should also prompt a vet visit, especially in older snakes. Many of these symptoms can have causes other than cancer, but it is always better to rule out serious conditions early. Finding a reptile experienced veterinarian in your area before you need one is a smart move for any snake owner.

How common is cancer in snakes?
Cancer occurs in snakes but is less commonly diagnosed than in mammals. This is partly because fewer snakes receive veterinary care and partly because some cancers go undetected. As more owners seek vet care for reptiles, more cases are being identified.
Can a snake survive cancer?
Yes, many snakes survive cancer, especially if it is caught early and treated surgically. Benign tumors have an excellent prognosis after removal. Malignant cancers have a more variable outcome depending on the type and how advanced it is at diagnosis.
What does a tumor look like on a snake?
Tumors typically appear as firm lumps or swellings under the skin. They can occur anywhere on the body and may be small or large. Some tumors cause visible changes to the scales or skin color in the affected area.
