Can Benadryl prevent mast cell tumors?

If your veterinarian is suspicious of a mast cell tumor and wants to sample it, they may recommend pre-medicating with Benadryl, an antihistamine. As we discussed above, one of the substances found in mast cells is histamine. Giving Benadryl may help prevent the tumor from degranulating during sampling.

Tumors can be irritating and dogs will scratch, lick, or bite the mass and surrounding skin. This trauma causes the tumor cells to release the chemicals in their granules leading to a localized reaction.
