Cancer: Local Spread vs. Metastasis

One of the most insidious things about cancer is the way it can spread. I’m not especially a fan of the way it can keep coming back after treatment, either, but that’s a story for another day. The American Cancer Society talks about two different types of spread: local or regional spread and metastasis. Local or regional spread is when a cancer extends beyond the organ in which it started. For example, a very large breast cancer could spread into the lymph nodes in the armpit or the lungs. Metastasis means that the cancer has moved to an entirely new … Continue reading

Dogs Helping to Refine Human Cancer Treatments

Approximately six million dogs are diagnosed with cancer each year. Companion animals with cancer can be used by researchers as models for human cancer, to help develop new treatments for man and animal alike. Comparative oncology isn’t a new idea. Dogs were used for testing bone marrow transplant techniques in the 1960s and 1970s. In the 1980s and 1990s, dogs were used to test limb-saving treatments for bone cancer. In 2003, the National Cancer Institute formally founded the Comparative Oncology Program, which aims to use pets to learn more about cancer — and to test and refine new therapies that … Continue reading

FDA Approves Cancer Drug for Canines

When our four-legged friends battle cancer, they often do it using the same medications used to fight cancer in humans. Until this week, human cancer drugs were the only type of cancer drug available to veterinarians. But now the U.S. Food and Drug Administration has approved Palladia — a drug made specifically for treating cancer in dogs. Palladia was made to treat cutaneous mast cell tumors — a type of cancer that is to blame for approximately one out of every five cases of skin cancer in dogs. Some of these tumors are small and easily removed; in some dogs, … Continue reading

FDA Takes Action against Fake Cancer Cures

I find it hard to believe that people out there are trying to get rich by selling fake cancer cures… but they’re out there. The U.S. Food and Drug Administration recently sent letters warning more than two dozen companies to stop selling fake cancer preventatives and cures. The companies are all over the world — most of the warning recipients are in the United States, but others in Canada and Australia have been targeted by the FDA. Those warning letters cover more than a hundred different tablets, tonics, creams, teas, and “black salves” that claim to cure or prevent cancer. … Continue reading
