Many things with anti-inflammatory properties are useful in treating cancers, since cancer typically coopts the inflammatory response in order to spread. The majority of mass in tumors are inflammation, surrounding cancerous cells.
Metacam is the veterinary name for a prescription anti-inflammatory that is prescribed for dogs and other animals to treat arthritis. It’s also prescribed off label for cancer in dogs. I know this because my chocolate lab, and best buddy, had cancer and I pulled out all the stops to try and help him. Metacam did wonders for him, and helped keep him comfortable, happy and alive for six months beyond the most optimistic prognosis for his advanced cancer. He lived to what is a grand old age for a lab, 14 1/2. I still miss him greatly.
This same drug is also used in humans, but the name escapes me right now.
Good. Good story.
