Risk of Cancer after Japan Tsunami, Not Going to be Noticeable According to WHO

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 north of Tokyo.

Some 110,000 people living around the Fukushima Dai-ichi nuclear plant were evacuated after the big 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.

Japanese Scientists manipulate T-cells to fight cancer, HIV using Stem Cells

Stem cell technology may one day give new life to tired immune cells so they can battle diseases such as HIV and cancer more effectively, two new studies suggest.

Scientists in Japan used old immune T-cells and regenerated them into T-cells that multiplied in greater numbers, had longer lifespans and showed a greater ability to target diseased cells. The finding could lead to more effective immune therapies, the researchers said.

Both reports were published in the Jan. 4 issue of the journal Cell Stem Cell.

“The system we established provides ‘young and active’ T-cells for adoptive immunotherapy against viral infection or cancers,” study senior author Dr. Hiromitsu Nakauchi, of the University of Tokyo, said in a journal news release.
