What to Expect After a Pet Cancer Diagnosis

Pet Cancer Treatment

The available pet cancer treatment options are much the same as cancer treatments for humans. The main difference is that pets tend to have fewer negative side effects with chemotherapy; they rarely experience nausea or lose their hair. Your pet is likely to have a better chance of survival if you follow the treatment plan laid out by your vet, which can include one or more of the following therapies.

Surgery

Surgery is used to remove cancerous growths and may be curative with some cancers, such as in complete removal of a low-grade mast cell tumour. Surgery can also be used in conjunction with other treatments to completely remove cancer from your pet's body.

Chemotherapy

This method uses medication to kill cancer cells and is part of most cancer treatment plans. Chemotherapy drugs can be taken orally in pill form or administered intravenously (into a vein) by a veterinary professional.

Radiation

Radiation is used to shrink tumours before surgery, kill cancer cells that are left behind after surgery, and slow down cancer growth in parts of the body where surgery isn't possible — in the nose, for example. Pets usually require several doses of radiation. Keep in mind that radiation centres are typically only available in highly specialised veterinary hospitals, and may involve high costs.

Immunotherapy

Immunotherapy uses a vaccine to stimulate a pet's immune system to fight off cancer cells. This therapy is used in canine melanoma and is being explored as an option to treat osteosarcoma.

Palliative Care

Pet cancer can't always be cured. Palliative care focuses on maximising your pet's quality of life during the time they have. This may involve controlling pain, minimising nausea and helping you understand when it's time to say goodbye. Palliative surgery may be used to stop pain, especially in dogs diagnosed with bone cancer. Also, good nutrition is essential during palliative care, so it’s important to have a conversation with your veterinarian to discuss diet and nutritional needs for your pet. The silver lining is that palliative care can often provide weeks to months of quality, pain-free time with your pet that you might not have otherwise had — and that's truly precious.

What to Expect When Your Pet Has Cancer

Depending on the type of cancer your pet has, their overall health and age, and the treatments they're receiving, there may be some changes at home. For example:

• If your pet has had surgery, they'll need time and at-home care to recover.
• Your pet may sleep more and eat less if they have a type of cancer that causes loss of appetite or energy. Don't push them to exercise, and let them self-regulate their activity. If you have a dog, continue to take them outside daily for fresh air and sunshine. If your pet isn't eating, your vet may prescribe an appetite stimulant or change their food.
• If your pet has brain cancer, you might notice changes in cognition such as loss of learned behaviours. They may also develop seizures, which will need to be managed with medication.
• Cancer or cancer treatments can sometimes cause urine or bowel control issues. Your pet may need to relieve themselves more often as a result, and may be more prone to accidents in the home.
• Expect frequent veterinary visits. If your pet is receiving treatment, your vet will need to do additional testing during and after treatment to assess how well it's working. Treatment can be costly, so if you have pet insurance, be sure to have a discussion with your provider at the earliest opportunity to understand what your policy covers.

When your pet is under palliative care, it can be hard to know when they need veterinary intervention and when it's time to say goodbye. The PDSA has a quality-of-life assessment checklist that may help. 

The concept of caregiver burden in humans caring for other sick humans is well documented, but according to research discussed in the British Medical Journal, it's also a very real problem faced by people who are caring for chronically or terminally ill pets. If you're the caregiver, take care of yourself and enlist support where you can. Organisations such as Blue Cross offer resources such as free and confidential counselling, along with opportunities to connect with other pet parents who understand what you’re going through. Contact the Blue Cross Pet Bereavement Support Service by phone on 0800 096 6606, by email at pbssmail@bluecross.org.uk, or online via live chat.

A pet cancer diagnosis can be overwhelming, but your vet is here to help you navigate the process. Grieving is also a normal part of dealing with pet cancer. If you're struggling, consider reaching out for support so you can make the most of the time you have left with your precious pet.
