Vumon is a chemotherapy drug used to treat certain types of cancer. The spelling of "Vumon" comes from a combination of the words "VM26" and "mitomycin." The IPA phonetic transcription for "Vumon" would be /vuːmɒn/. The "V" is pronounced like the "v" in "very," the "u" like the "oo" in "soon," the "m" is pronounced normally, and the "n" like the "n" in "noon." The stress is on the first syllable, hence the long "u" sound.
