Targeted therapy is an advanced treatment option for certain types of cancer. Before initiating the treatment, the cancer cells are evaluated to determine if they will respond to the treatment. Targeted therapy is generally used in patients with advanced cancer when other treatment options are ineffective. Targeted therapy targets the cellular processes essential for the division, growth, and spread of cancer cells.
Targeted therapy has been approved for treating several types of cancers. These include cancers of the brain, bladder, esophagus, endometrium, kidney, head and neck, skin, lung, prostate, and thyroid.
The side effects of targeted therapy are liver problems, diarrhea, fatigue, oral sores, high blood pressure, altered nails, delayed wound healing, and blood clotting disorders.
