What is Fibrosarcoma?

Your pet bird is living longer that his wild country cousins, and over the lifetime, cancer may occur due to the longevity of your bird and the accumulation over time of disrupted cells turning to cancer. This may be caused through diet, extremes in climatic changes, and stresses that they encounter over their lifetime. Fibrosarcoma, described as tumors arising from the connective tissue, are the most common cancer found in birds, with the leg or wing being the most likely location. They feel firm to touch, with a mass forming around a long bone.

Cancer in your bird is the result of an accumulation of cells which for many reasons, grow and replicate gradually getting out of control.

Symptoms of Fibrosarcoma in Birds

  • Over time this common type of cancer can move to the lung, liver or bone
  • A large mass forming around the bone often in the leg or wing area
  • Locally invasive
  • The cancer can reoccur even after surgical removal 
  • It may be ulcerated from your bird picking and worrying the growth 
  • Cutaneous forms can inhibit the beak area 
  • Nodular raised red surface on the skin 


  • Fibrosarcoma is a cancer that affects the connective tissues and grows over a long bone such as a wing
  • As the cancer starts to grow and expands stretching the skin, your bird may start pecking at it causing it to ulcerate
  • The bird species most affected are usually cockatiels, macaws, budgerigars, and other types of parrots
  • It can develop deep in the oral cavity or abdomen cavity or even in the bone
  • It can spread (metastasize) to other organs in your bird’s body


Causes of Fibrosarcoma in Birds

  • While no one really knows what causes cancer, there are certain things that may contribute to its development
  • Diet can certainly be part of the cause, an inappropriate diet causing lack of vital nutrients could lead to cancer forming
  • Exposure to toxic chemicals may do long term harm in causing a reaction such as cancer in your bird’s body
  • Stress is often cited as a cause, if your bird has endured a lot of stress then that may trigger
  • Your bird’s immune system may have be compromised


Diagnosis of Fibrosarcoma in Birds

The first symptom you may notice is a large mass forming on your bird’s wing or leg. As soon as you notice this, consult your veterinarian to schedule an examination. During the physical exam, he will probably take a sample of tissue using a fine needle aspiration, wedge, punch or surgical biopsy. This tissue sample will be examined under a microscope to diagnose what the condition is. If the condition is confirmed as a fibrosarcoma then you can discuss treatment options with your specialist.

These cancers can grow to a large mass, and can also spread to the organs of your bird. Although this is distressing news for you as an owner, there are options available. A lot will depend on the extent of the growth and we must consider the quality of life before and after treatment. Your veterinarian will be able to explain the treatment options available, and advise on recovery and care



Treatment of Fibrosarcoma in Birds

If the mass is on the wing, amputation of the wing is a very real option. Birds that have had this done have gone on to lead full rich lives, even if they only have one wing. Of course, if your bird flies a lot that may be quite a decision to make as your bird may be distressed over losing a wing. Amputation removes all the mass, and if the cancer hasn’t spread to other areas, your pet may live on to a ripe old age.

Other options are surgery to remove the mass. This option prognosis is guarded as total recovery depends on removing the total mass, and sometimes it is hard to see if it has affected other tissue. The chance of the cancer reoccurring is a lot higher than the amputation option. Radiation and chemotherapy are alternatives to be considered although the results from such treatments are guarded. Another element to consider is the age of your bird. If it is in his last years, maybe it is kinder to allow him a quality of life in his remaining years. With cancer, there is no guaranteed cure yet.

Recovery of Fibrosarcoma in Birds

If your bird has had an amputation, gentle care while he recovers will be necessary. There will be a time of adjustment to life with one wing, but birds are amazing creatures and adapt readily. Attention to the wound and keeping the bandages clean are necessary to ensure infection doesn’t set in. This applies also to surgical removal of the mass; the dressings must be kept clean and sterile. Chemotherapy and radiation reactions are always unknown and cannot be guaranteed but a quiet clean cage, plenty of fresh water and a variety of quality food will be essential to help them to heal. Keep the cat away from the cage so as not to stress your bird, and allow a quiet dark room for plenty of sleep at night.
