わが国は世界でも有数の長寿国です。しかし、食生活や運動習慣に起因する生活習慣病患者および死亡者の増加、増大する医療費は深刻な問題となっています。なかでもがんは日本人の死亡原因の第一位となっています。がんを克服するためには早期発見が欠かせません。このがんの発見に有効な手段として注目されているのが、PETと呼ばれる画像診断法です。
現在、がんは日本人の死亡原因の第一位であり、死亡者数も一貫して増加しつづけ、平成28年にはついに年間35万人を超えました。がんになる人は年間約50万人で、一生のうちにおよそ2人に1人の割合で、がんにかかるといわれています。しかも働き盛りの50代では、亡くなる方の約半数が、がんによるものなのです。
がんは必ずしも不治の病ではありません。早期に発見し、治療することができれば、生存率は大幅にアップします。胃がん、大腸がん、子宮がん、乳がんなどの早期がんは、その多くが治癒しています。また、今までは治りにくかった、肺がんや、肝臓がん、すい臓がんなども、早期に発見されれば治す事も可能です。

一般人集団の生存確率(A)に対する、がん治療5年後の患者集団の生存確率(B)の比(B/A)。
がんの早期発見・早期治療は、身体への負担を少なくするだけでなく、経済的な負担も軽くします。がんで死亡された方の平均医療費は約420万円*ですが、がんを治癒された方の平均医療費は約200万円*であるとのデータがあります。早期がんの治療では、入院期間も短く、医療費も少なくおさえることができます。
