Cancer is a broad term used for diseases in which abnormal cells divide uncontrollably and spread to other parts of the body. Pets, just like humans, can develop cancer as they age. While pet cancers can vary in type and severity, some of the most common include bone cancer, skin cancer, lymphoma, melanoma, and mast cell tumors. The good news is that much progress has been made in recent years regarding pet cancer treatment.
Standard Treatment Options
Surgery remains a mainstay of Pet Cancer Therapeutics when possible. Depending on the size, location and type of tumor, surgical removal aims to get clear margins of healthy tissue around the mass. For localized cancers, surgery may be curative if no cancer cells remain. Radiation therapy uses high-energy beams such as x-rays or protons to kill cancer cells and shrink tumors. It can be administered alone or in combination with other therapies. Chemotherapy involves the use of anti-cancer drugs that travel through the bloodstream, destroying cancerous cells that have broken off from the primary tumor site and spread throughout the body.
New Drugs and Personalized Medicine
Significant advancements have been made in pet cancer drug development, including targeted therapies and immunotherapies. Some newer chemotherapy drugs are proving effective against certain cancers while exhibiting lower toxicity. Some drugs originally developed and approved for human cancers are now being used to treat pets. One example is masitinib, an oral drug designed to target mast cell tumors in dogs. As researchers gain a deeper understanding of cancer at the molecular level, more personalized treatment approaches are emerging. Oncologists can analyze biopsied tumor cells to select drugs tailored to the genetic mutations driving an individual pet's cancer. This leads to more effective response rates and better quality of life during treatment.
Complementary and Integrative Therapies
While standard therapies remain the mainstay, integrative therapies are gaining acceptance and use among holistic veterinarians. These aim to boost the immune system and reduce side effects from conventional treatment. Some integrative options include acupuncture, herbal supplements, nutrition and lifestyle changes. For instance, certain herbs like curcumin from turmeric or vitamins like A and C may have anti-cancer properties and synergize well with drugs. Diet can also play a role, with some evidence restricted calorie diets may stunt tumor growth. While complementary therapies cannot replace surgery, chemotherapy or radiation, they provide value by enhancing wellbeing and comfort during cancer care.
Managing Side Effects of Treatment
While lifesaving, conventional therapies like chemotherapy and radiation do come with potential adverse effects. Common issues include nausea, loss of appetite, fatigue, diarrhea and mouth sores. Fortunately, better medications and supportive care allow veterinarians to effectively minimize side effects for pets undergoing treatment. Antinausea drugs, nutritional supplements, and palliative care can keep pets more comfortable and improve their quality of life. Laser therapy and massage may additionally help manage pain or inflammation. With diligent monitoring and management, pets are able to tolerate therapies well and experience less disruption to their daily activities.
Latest Advances and Outlook for the Future
Areas of active research aim to further improve pet cancer treatment outcomes. Immuno-oncology hopes to harness a pet's own immune system to fight tumors, with promising early results for vaccines, chemokines and checkpoint inhibitors. Gene therapy may one day deliver cancer-fighting genes directly to tumors. Stem cell transplants offer potential to enhance conventional therapies. Nanoparticles are under study to allow drugs to specifically target cancer sites. Hyperthermia uses heat to destroy tumor cells alongside chemo or radiation. With continued progress, cancer may become increasingly manageable as a chronic yet controlled disease for many pets, allowing them longer, high-quality lives alongside their loved human families.
While still devastating for some, pet cancer is no longer an automatic death sentence due to the new tools, knowledge and standards of care that veterinary oncology can bring to the table. With early detection, personalized treatment selection and vigilant monitoring throughout, many pets achieve remission and long-term survival outcomes now akin to the human experience. Cutting-edge therapies will likely continue refining quality of life during care for both pet and owner. With an improved understanding of cancer at its most fundamental levels, future therapies will continue delivering ever-greater benefits against this widespread disease.
