Men who have been treated for breast cancer face a significantly high risk of getting cancer once again, University of California, Irvine researchers said in a news release.

Their study found that 11.5 percent of these men ultimately developed second primary cancers within two months, particularly those of the breast, stomach and skin.

The researchers recommended that men who have suffered from breast cancer need to be more closely monitored for this second onset of cancer.

And in further comparisons to the general population of men, the researchers observed higher rates of breast, colorectal, bladder and stomach cancers and of melanoma in men who have had breast cancer.

"Even more disturbing, we found that men with breast cancer are diagnosed with later-stage disease and that patients with onset of the disease at a young age are even more likely to develop a second cancer," said Hoda Anton-Culver, who is chief of epidemiology in the UCI School of Medicine.

Study results appear in the open-access journal Breast Cancer Research.

Male breast cancer is rare, afflicting about 1,700 men in the United States a year.
