Session 1 (tutorial session): Radiation and Thyroid CancerSummary
Many patients with thyroid cancer were found in the Fukushima Health Management survey and people are worried about the effects of radiation from the accident.
The global incidence of thyroid cancer has been increasing sine approximately 30 years.
In the Chernobyl accident young children, zero to 9 years are at higher risk of thyroid cancer, with the incidence of thyroid cancer appearing in increase beginning at 0.1
Gy
at ages zero to 17 years.
94.9% of people in Fukushima Prefecture at the time of the accident (except site workers) received a dose of <2.0 mSv and 66% received a dose of <1 mSv. (as of December 2013)
Slide2Session 1 (tutorial session): Radiation and Thyroid CancerSummary - Continued
Even
advanced
stages of thyroid cancer after radiation exposure can be treated effectively with surgery,
radioidine
therapy and thyroid hormone
supplements
.
The
current
high prevalence of
in thyroid
cancer
recently found in Fukushima Prefecture is
highly likely
attributable to screening.
Thyroid cancer
occurance
is influenced by:
Change in risk factors
Change in diagnosis and detection
Methodology considerations
Slide3Session 1 (tutorial session): Radiation and Thyroid CancerSummary - Continued
Perception by stakeholders is everything.
Risk communications and dialogue is
better
locally oriented than centrally managed.
Recommendations
–
Continue and strengthen the Fukushima Health Management Survey.
Develop a population based Cancer Registry.
Enable linkage of
data over time and end-points.
Implement a Primary Prevention Program
.
Use of observation, for low risk papillary patients was found to be an effective treatment therapy
.
Establish an effective, locally based Risk Communications Program.
