Cold Laser for Cancer in Dogs: What To Know

Updated: August 16th, 2021

Summary

Does cold laser therapy used on cancer tumors cause them to grow, or to shrink? Dr. Dressler explains when — and when not — to use this type of tool.

So, should you use cold laser therapy to TREAT dog cancer? On today’s Dog Cancer Answers episode, Dr. Demian Dressler explains why … or why not.

The short answer is that it depends upon the tumor itself. There is no one right answer.

If your veterinarian can penetrate to the tumor itself using their equipment — maybe. (Not all tumors are within range of the cold laser!)

If the tumor doesn’t have a lot of blood vessels attached, cold laser could be useful. It would stimulate blood flow and help kill the tumor.

But if there are lots of blood vessels in the area … cold laser therapy could help the tumor to grow by sending TOO MUCH circulation!

So this is something you have to really go over with your veterinarian. Dr. Dressler recommends asking your veterinarian the following BEFORE approving cold laser therapy for your dog’s cancer treatment:

  1. Is this a highly vascular tumor? [Many vets can’t/won’t be able to do a CT scan to check out the area for blood vessels.]
  2. Will your equipment be able to reach the tumor?

If your vet hems and has about the answer to either of these questions, it’s probably not worth pursuing. If you don’t know where the tumor is, how vascular it is, or if it’s within range of the cold laser therapy equipment … why do it at all?
