Excess iron in men also elevates cancer incidence, so I don't think one should take an iron supplement if there's no need. A blood test is necessary. If you look closely at the men and women's multivitamins that are sold in stores, you'll see that there is no iron on the men's multivits.

Excess iron can be reduced by donating blood.
