Indications for Fluorouracil
Fluorouracil 5 topical cream is an antimetabolite used for chemotherapy. Antimetabolites, like the name suggests, are a toxic compound that prevent cells from metabolizing, thereby halting cell growth. It is this damage to the metabolism of cells that prevents mutated cells (i.e., carcinoma or sarcoma) from spreading. The medication has no way of specifically targeting only the mutated cells, meaning that it prevents all cell growth within a wide area, which can be quite painful. However, as far as dog skin cancer treatments are concerned, the benefits often greatly outweigh the risks.
