Targeted therapy is a more specific type of cancer treatment that focuses on specific molecules and genes involved in the proliferation of cancer. It differs from chemotherapy, as this form of therapy affects both normal and abnormal cells. Targeted therapy zeroes in on cancer cells, hoping to destroy their capacity to multiply and grow. The targeted approach of this treatment restricts the damage to the normal cells, thus minimizing the side effects on patients. The doctors can determine which targeted therapy is more likely to work based on the genetic profile of a patient’s cancer. This treatment can block signals that tell cancer cells to grow, cut off their blood supply, or directly attack cancer cells. As research advances, targeted therapies continue to evolve, offering new hope for patients with difficult-to-treat cancers. With discoveries, targeted therapies are developed, and a glimmer of hope is once again seen in patients whose cancer is resistant to conventional treatments. Target therapy reduces unnecessary damage to the healthy issue, hence speedy recovery times. It is a vision of tomorrow that changed the way cancer is treated. Patients can now be given treatments well-tailored to their unique genetic makeup.
