I would not get hopes for humans up too much. From the dog cancers I’ve seen they are slow growing and must not metastisize quickly. We’ve had growths the size of chiceken eggs removed surgically from our Golden Retreiver, no recurrance and she’s now almost 14.
On the the other hand, a spot the size of a pencil eraser in my sister’s lung killed her in less than a year.
Something smells about this....though I would like to be wrong...and this is comimg from an RN with 24 years in the business!
