で満足すべき治療効果を挙げていない。
Surgical therapy, radiotherapy, and chemotherapy have been mainly attempted for the treatment of cancer, but none of these treatments have shown satisfactory therapeutic effects in terms of cancer recurrence and survival prolongation.

One of the reasons for this is that even though these treatments can reduce or remove the primary cancer tumor, the cancer can spread to other parts of the body, especially major organs such as the brain, lungs, or liver. This is because it will lead to fatal consequences.

Therefore, in addition to treatments that reduce the size of the primary cancer tumor or surgically remove the cancer, it is extremely important to prevent cancer metastasis in order to completely cure cancer.
