PORTLAND, Ore. (KOIN) — The Oregon Health Authority released data of cancer rates over a 15-year period in parts of North and Southeast Portland.

The data is from neighborhoods close to Uroboros and Bullseye Glass.

The analyses were done in 5-year increments between 1999 and 2013.

OHA says the cancers most associated with arsenic and cadmium exposure, lung and bladder, were consistent with expected rates with one exception. Between 1999 and 2003, the observed number of bladder cases was 7, which was higher than the expected number of 3.

The OHA calls this statistically significant, even though it is a small increase. The report also stresses it can’t determine the exact cause of the cancer.
