What are the symptoms of stereotactic radiation therapy in dogs?
Stereotactic Radiation Therapy Procedure in Dogs. The intense accuracy the CyberKnife achieves gives SRT its edge: the expected symptoms of typical radiation therapy (vomiting, fatigue, weakness) are not present because only cancerous tissue is exposed to the radiation.
How quickly does radiation work on cancer in dogs?
How quickly radiation therapy works depends on the tumor. Some, especially those growing rapidly, may regress very quickly. Other may shrink some during treatment and continue to shrink over following weeks or months. Many pet owners have concerns about the side effects of radiation treatment.
What can I expect after my dog gets radiation?
What Are the Benefits and Side Effects of Radiation? The most common side effects of radiation therapy in dogs are similar to those in people. The patients may experience skin redness or moisture for a short period of time. In cats the side effects are milder and may just be limited to short-term dry, flaky skin.

Early effects are seen during or shortly after radiation treatment, usually 2 weeks after starting radiation and continuing for about 2 weeks after radiation therapy is completed.
How long do radiation side effects last in dogs?
Pets usually experience acute side effects for 3-4 weeks. Chronic side effects, when they occur, develop gradually over months to years. This includes fibrosis (scar tissue formation) and decreased ability to heal a wound or bone fracture.
How well do dogs tolerate radiation therapy?
“Overall, dogs, cats, and other animals tolerate radiation therapy better than people,” says Dr. Lee. Side effects occur only in the area that is treated with radiation, which includes the tumor and a small margin of healthy tissue surrounding it.
How long does it take for a tumor to shrink after radiation?
At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).
Is radiation therapy for dogs painful?
Radiation therapy is not painful. The overall radiation dose prescribed is divided into small, daily or weekly treatments. Because there is no pain associated with the treatments, we use sedation or light anesthesia only to ensure that there is limited movement during treatment.
Does radiation shrink tumors in dogs?
Radiation therapy works by damaging the cells' DNA to interfere with cell replication and kill them. In this way, radiation can either shrink a tumor or completely destroy it.

What is the tumor on my micro tea cup poodle?
My very tiny, micro tea cup poodle was recently diagnosed with a nasal tumor in his sinuses directly behind his left eye, that his encroaching on his upper jaw bone. Surgery is not an option because of his size and tumors location. To say this diagnosis came as a shock is an understatement. We thought he had a cold for a few weeks that we were treating with his vet, until it became absolutely necessary for him to have a CT scan. (since he is so tiny, 3.0lbs) we never have him out under any anesthetic, even his teeth cleaning are done with the waterpik technique) after the shock and searching for any possible options, we met with Dr. Arkans, an oncologist at the MedVet Hospital in Chicago and came up with a plan for 5 treatments of SRT radiation therapy. By God's grace, the Dr's talents and the technicians care, my tiny little man came through the treatments (every day for 5 consecutive days with full anesthesia). He's currently healing. I wish I could say he's cured but radiation will only halt the growth not remove the tumor. He's a strong little thing and if love alone could cure him, I would have no reason to write this because he'd be healthy already. I can say, so far the SRT radiation seems to be making a difference. For how long, I have no idea. His quality of life is still very good. Eating is difficult as his mouth seems to be sensitive so I feed him beef baby food through a 1ml syringe. time will tell. If surgery isn't an option for your pet and radiation is the only choice (or chance) check into SRT radiation.
How much does SRT cost?
SRT costs typically range from $2,000 to $9,000. Due to the fact that the final cost of the procedure relies on individual circumstances (i.e. the size of your dog, the number or size of tumors, etc.), this cost can be more. While you may save money on less office visits, no required overnight healing, and lack of administered anesthesia, the process of SRT relies on computer imaging formed through CT scans ($500 upwards), x-rays ($150 upwards), MRIs (upwards of $1,400), or ultrasounds ($260 upwards).

How does radiation therapy work?
Radiation makes cells unable to replicate. The idea is to eliminate the cancer cells so that they can no longer divide and spread. Because both normal and cancer cells are affected, the radiation machine can be positioned in the specific area of the tumor.
What are the benefits of radiation therapy?
Radiation therapy can offer, in some instances, a cure for the cancer. Even when a cure is not possible, radiation therapy can still bring some relief. Shrinking a large tumor with radiation therapy may improve a pet's quality of life by reducing pressure, bleeding, or pain. This is called palliative treatment.
Are there risks involved?
There are some risks involved with any type of cancer treatment. In addition to cancer cells, some normal cells will also be killed by the radiation. Some side effects may be apparent because of normal cells being killed (e.g. "radiation dermatitis"). Usually, these side effects are outweighed by the benefits of killing cancer cells.
How is the therapy given?
A linear accelerator directs a radiation beam toward the cancer and some normal tissues around it. The equipment is in many ways similar to equipment used for standard X-rays, except that the energy of the radiation beam is much higher and the exposure times are much longer. The treatment takes approximately 5-20 minutes.
Is radiation therapy ever used in combination with chemotherapy or surgery?
Yes. In situations where it is unlikely that any one method of cancer treatment will be effective, such as with large or aggressive tumors, radiation therapy can be combined with surgery or chemotherapy. In some situations, a combination of all three types of treatment may be recommended.
How long does the entire treatment last, and what is the treatment schedule?
Radiation therapy is given in a series of treatments over many weeks. Depending on the type of cancer and the intent of treatment, it can range anywhere from 1 week to 2 months. This schedule helps to protect normal tissue by spreading out the total dose of radiation.

What is radiation therapy for pets?
For most of us in the veterinary field, radiation therapy is a mysterious treatment that occurs elsewhere or it is a modality that a family member or friend underwent. However, because it is so effective in treating people with cancer (and with the guidance of Dr. Google), more and more clients are asking about the use of this treatment in their pets. For many of us, we really haven’t been trained on how to discuss this treatment option with clients. So, I wanted to go over some of the nuts and bolts of what clients can expect when choosing radiation therapy for their pet. A number of parameters are evaluated to determine if radiation therapy can benefit a patient and what course of radiation therapy is most appropriate. These variables can include: expected outcome, tumor responsiveness, tumor location, presence of microscopic versus macroscopic disease, machine and software capability, and if concurrent or follow-up treatments are planned.
How does radiation work?
Radiation works by damaging the DNA of affected cells, leading to cell death. Because radiation is not selective about healthy or neoplastic cells, the goal is to target as many tumor cells as possible with this high energy radiation while avoiding damage to the normal surrounding tissue.

What Is Radiation?
Radiation can be broadly divided into two groups: electromagnetic and particulate radiation. Whether you know it or not, you interact with electromagnetic radiation every day. It consists of packets of energy, called photons, with no mass or charge. Common examples include microwaves, visible light, and radio waves.
How Does Radiation Therapy Work?
Radiation fights cancer by interacting with strands of DNA in cells, causing breakages that make the cell unable to replicate, meaning a cancer cell can no longer divide to make two daughter cells. When the damaged cell tries to divide, it collapses and is cleared away by the body.
How Much Radiation Is Given?
