We cover the meaning of cancer targeting, and how to target cancer. Nowadays, there are many not only drugs but also treatments for cancer treatment, but they have some problems.
1. Chemical-based Anticancer drugs
These chemical-based drugs are systemic drug. Therefore, normal cells are also regarded as cancer cells and become treated. Normal cells are attacked by chemical-drug, a

Less than half of infected persons are eligible fortreatment based on current guidelines(only eligible at advanced stages of diseases)
Treatment must be administered for lifetime and does not cure infection
Treatment regimens are complex, toxic, and expensive.
For every new person started on treatment in 2006, approximately 6 new infe
