Cancer is the uncontrolled division of body cells. It may spread to surrounding tissues and may also spread to different parts of the body. Just like humans, cancer in pets is also on the rise. It is more prevalent in dogs above the age of 8 years of age. Some of the breeds who are more susceptible to cancer as compared to others, and those are – Rottweiler, Great Dane, Labrador, Beagle, Poodle, Doberman, Cocker Spaniel, Boxer, German Shepherd, Golden Retriever, Burmese Mountain dog, Scottish Terrier, and Bull Mastiff.

There are 4 stages of cancer –

  • Stage I – only a small size growth is seen
  • Stage II – fast increase in size of the growth
  • Stage III – it involves the lymph nodes
  • Stage IV – metastasis in other organs such as lungs, liver, etc.

There are two types of cancers – benign cancer and malignant cancer.

Benign cancer is a slow-growing tumour and is safe. Malignant cancer, on the other hand, is fast-growing and dangerous type of cancer.

Different types of cancer in pets

Some of the most common types of cancers in pets are as follows –

  • Lymphoma – a type of cancer that originates from the lymphatic system.
  • Melanoma – a type of cancer that originates in melanocytes, the cells that produce pigment in the skin.
  • Mastocytoma – a type of cancer that originates in the mast cells, which are a part of the immune system.
  • Osteosarcoma – a type of bone cancer that primarily affects the long bones, such as those in the legs.
  • Hemangiosarcoma – a type of cancer that originates in the cells lining blood vessels.
  • Fibrosarcoma – a type of soft tissue sarcoma that can occur in various connective tissues, such as muscle, fat, and fibrous tissues. In pets, it can result in tumours in different parts of the body.
  • Tumours – mammary tumour or breast cancer, nasal tumour, oral tumour, skin tumour.
  • Liver cancer
  • Blood cancer
  • Stomach cancer
  • Perianal adenoma – a benign tumour that occurs in the perianal area of male dogs, particularly those that are not neutered.
  • Histiocytoma – a benign skin tumour that commonly affects young dogs.
  • Papilloma – is a benign growth caused by certain types of viruses.

Mast cell tumour is the most common type of cancer seen in dogs. Hemangiosarcoma of the spleen is a fast-growing cancer of dogs and there are chances that it also spreads to the heart, liver, and kidneys.

Unmasking the menace with the right diagnosis

Your vet may use different diagnosis methods to determine the severity of cancer in your pet. These include – a rectal examination, endoscopy, X-ray of the abdomen area, USG of the abdomen area, CECT scan/ MRI/ PET scan, urine examination, fine needle aspiration cytology of cancerous growth.

Your vet can also recommend a CBC – if the white blood cell count is quite high and red blood cells are extremely low, it is suspected to be cancer in pets. A biochemical profile – hypercalcemia in dogs, hyperglobulinemia (in case of myeloma)indicate cancer in 70% of cases.
