How is dog cancer treated?

Depends in great measure of the type, size and location of the tumor. It could be operated and extirpated, but there is also the risk that it can reappear (particularly a malign one) in the same or another part of the body. A surgical refinement is the cryosurgery, by which a liquid gas like nitrogen, at a very low temperature, is applied to the affected tissue. The intense cold kills the cells, avoiding the need of an incision. The region close to the tumor is covered for protection while using the probe. Cryosurgery has many advantages in relation to surgery, particularly in case of skin tumors. As there's no bleeding, there are less probabilities, in case of a malign tumor, that cells can spread all over the body creating secondary tumors in other zones.Using cryosurgery in some delicate zones can also be treated, for example, around the anus, that will bleed in abundance if the tumor is cut. Likewise, there is less danger of infections after operation. The major inconvenience with cryosurgery is that the frozen tissue does not give up at the beginning, and it bothers to wait for it. Treatment can also be repeated if one of the altered tissues doesn't reacts accordingly. Cryosurgery is also applied for skin diseases, like the wart, where there are small fluids. Frozen crystals formed will break the living tissue cellular structure after freezing. There is now a common practice to inject water to warts for better results. Cryosurgery does not always succeeds, specially in the case of tumors in the internal parts of the body. In this case, a radiation therapy could be more effective, alongside a chemotherapy including the use of drugs. Secondary effects of these drugs, normally, are not so distasteful for dogs, as they are for human beings. If radiation therapy is not available in your city, you'll, have to find some other veterinary clinic with these facilities.
