What Causes Cancer in Cats?

Cancer in cats is caused by exposure to carcinogens and unhealthy lifestyles.

Common carcinogens include tobacco smoke (second and third-hand), asbestos, x-rays, prolonged sunlight, benzene, and food additives. 

An unhealthy lifestyle, particularly a lack of physical exercise and low-quality nutrition, are important risk factors in the development of cancer in cats. 

Cancer is more common in senior cats, suggesting a link between cancer risk and old age. 

The exact trigger of cancer in cats is rarely found. Cancer is multifactorial and typically caused by a combination of the above-mentioned risk factors.  

What are the Symptoms of Cat Cancer?

The symptoms of cat cancer include lumps and bumps that change size, foul odors, slow-healing wounds and sores, appetite changes, body weight fluctuations, reduced energy, seizures, digestive distress, respiratory problems, and urinary issues. 

The symptoms of cat cancer are listed and reviewed below.

  • Lumps, Bumps, and Growths: The most striking symptoms of cancer in cats are lumps, bumps, or growths on the body that change size and appearance.
  • Foul Odors: Cats emitting foul odors are a common symptom of cancer in cats. The most common trigger is cancer affecting the oral cavity, in which case the cat develops bad breath or halitosis. 
  • Slow-Healing Wounds and Sores: Reduced or lack of healing ability is another typical cancer sign. Wounds form when the lump or bumps ulcerate, and the impaired healing is due to the cancer’s debilitating effect on the cat’s immune system. 
  • Increased or Decreased Appetite: Cats with cancer eat more or less than usual. Eating more and eating less are both dangerous for the cat’s overall well-being.  
  • Body Weight Fluctuations: Appetite changes directly affect the cat’s body weight, causing weight loss or gain. 
  • Reduced Energy Levels: Cancer cats have reduced energy levels, sleep more, and show disinterest in everyday activities. Sudden depression in cats is concerning and requires immediate veterinary attention. 
  • Seizures: Seizures develop in cats with brain tumors and present with sudden and uncontrolled movements, loss of consciousness, jerking limbs, foaming at the mouth, sudden rage, and excessive biting. 
  • Digestive Distress: Digestive upset symptoms in cats with cancer include nausea, vomiting, diarrhea, abdominal swelling, and blood in the feces. 
  • Respiratory Problems: Coughing, high-pitched wheezing, chronic nasal discharge, and difficulty breathing are respiratory symptoms observed when cancer spreads to the cat’s lungs. 
  • Urinary Issues: Cats with bladder cancer urinate in unusual places around the house. Other urinary cancer symptoms include frequent or painful urination and blood in the urine. 

How often does a Cat have Cancer?

Cancer affects one in five cats, according to the American Cancer Foundation (ACF). Over 6 million cats are diagnosed with cancer annually, and approximately 26% of the cat population dies due to feline cancer.

The four most common types of cancer in cats are mast cell tumors, lymphoma, squamous cell carcinoma, and bone cancer. Other frequently diagnosed types are injection-site sarcoma (ISS), mammary cancer, feline leukemia virus (FeLV), and brain tumors. 

How does CBD Oil help treat Cats with Cancer?

CBD oil helps treat cats with cancer because it is a phytocannabinoid with antitumor and anticancer properties that support cats with cancer through the endocannabinoid system (ECS). 

CBD, or cannabidiol, is a plant extract sourced from hemp. ECS is a regulatory system that manages various bodily functions and consists of endocannabinoids, cannabinoid receptors, and enzymes. 

Cannabidiol binds with the cannabinoid receptors, thus promoting homeostasis or a state of balance. Studies on CBD oil and cancer describe CBD as a “promising anti-cancer drug” that  help cats with cancer on various levels.

CBD for cats with cancer acts against the cancer itself. Cannabidiol induces apoptosis (programmed cell death) of cancerous cells, shrinks tumors, and prevents metastasis. 

Pet CBD has strong antioxidant properties and boosts the immune system while reducing pain and inflammation, which is helpful in cats with cancer. Cannabidiol relieves pain and anxiety, often linked with cancer or cancer treatment. 

CBD for cats is safe to use in combination with traditional cancer treatments, such as chemotherapy and radiation. CBD oil and CBD treats boost the efficacy of mainstream treatments and help manage the side effects of vomiting and nausea. 

The recommended CBD dose for cats with cancer is between 4 and 6 mg of CBD per 10 pounds of body weight. Cancer requires higher CBD amounts than the usual recommendation of between 1 and 5 mg of CBD per 10 pounds of body weight. 

Start with a lower CBD dose and increase gradually as the cat gets used to the CBD supplement. Do not fret if the cat consumes more CBD than necessary, as hemp cannabis does not cause overdoses in pets. 

Consult with a licensed veterinarian regarding the ideal starting CBD dose or use an online available CBD dosage calculator. 

How often should CBD Oils be given to Cats with Cancer?

CBD oils should be given to cats with cancer every day. Cannabidiol needs time to build up in the cat’s body and exert positive long-term effects. 

It is recommended to give CBD oils to cats with cancer every day for at least three weeks before expecting to see an improvement. 

Hemp-sourced CBD products for cats with cancer are natural and safe to administer daily and up to several times a day.

Does CBD Oil shrink tumors?

Yes, CBD shrinks tumors. Studies have shown CBD shrinks certain types of tumors in some animals.

A similar effect was shown in another glioma cell research in 2020 titled “Cannabidiol (CBD) as a Promising Anti-Cancer Drug.” The study evaluates the CBD’s different anti-cancer properties and says that cannabidiol can “reduce the size of tumors.”

Does CBD Oil help treat lymphoma?

Yes, CBD Oil helps treat lymphoma. Feline leukemia is often mistaken for lymphoma in cats. 

The American Association for Cancer Research (AACR) published a study titled “Anti-proliferative effect of cannabidiol (CBD) against B and T-cell lymphoma” in 2020. The study says that “cannabinoids have an anti-proliferative and apoptotic effect on canine lymphoma cells.”

The study is not specific to cats, but CBD has similar effects in all mammals with an endocannabinoid system. The positive effects of CBD on lymphoma and cats with cancer are likely to be possible in cats, too. 

Is CBD Oil Safe for Cats?

Yes, CBD oils are perfectly safe for cats. 

CBD is “very safe for cats,” according to an article on PetMD. The World Health Organization (WHO), in its critical review of cannabis, says that “CBD is generally well-tolerated, with a good safety profile.”

CBD helps fight cancer in cats by assisting traditional anti-cancer treatment to shrink the tumor. Cannabinoids have several anti-cancer features that help reduce the size of tumors and prevent the spread of tumor cells throughout the body.
