Today, cancer detection happens mainly when symptoms appear. That is, at stage 3 or 4, and I believe that is too late. It is too expensive for our families. It is too expensive for humanity. We cannot lose the war against cancer. It not only costs us billions of dollars,but it also costs us the people we love.
