WHO predicts slightly higher cancer risk after Fukushima disaster

PanARMENIAN.Net - People exposed to the highest doses of radiation during Japan's Fukushima nuclear plant disaster in 2011 may have a slightly higher risk of cancer but one so small it probably won't be detectable, the World Health Organization said in a report released Thursday, February 28, according to AP.

A group of experts convened by the agency assessed the risk of various cancers based on estimates of how much radiation people at the epicenter of the nuclear disaster received, namely those directly under the plumes of radiation in the most affected communities in Fukushima, a rural agricultural area about 150 miles (240 kilometers) north of Tokyo.

Some 110,000 people living around the Fukushima Dai-ichi nuclear plant were evacuated after the massive March 11, 2011, earthquake and tsunami knocked out the plant's power and cooling systems, causing meltdowns in three reactors and spewing radiation into the surrounding air, soil and water.

Experts calculated that people in the most affected regions had an additional 4 to 7 percent overall risk of developing cancers, including leukemia and breast cancer. In Japan, men have about a 41 percent lifetime risk of developing cancer of an organ, while a woman's lifetime risk is about 29 percent. For those most hit by the radiation after Fukushima, their chances of cancer would rise by about 1 percent.

Experts had been particularly worried about a spike in thyroid cancer, since iodine released in nuclear accidents is absorbed by the thyroid, especially in children. After the Chernobyl disaster, about 6,000 children exposed to radiation later developed thyroid cancer because many drank contaminated milk after the accident.

For people beyond the most directly affected areas of Fukushima, Wakeford said the projected risk from the radiation dropped dramatically. Some experts said it was surprising that any increase in cancer was even predicted and believe that the low-dose radiation people in Fukushima received hasn't been proven to raise the chances of cancer.
