Nuclear Medicine & Radiation Therapy

Cancer is a disease that is characterized by the uncontrolled growth and spread of abnormal cells in the body. There are various treatments available to combat this disease, including chemotherapy, surgery and radiation therapy. Radiation therapy is a form of cancer treatment that uses high-energy radiation to kill cancer cells or prevent them from growing and dividing further. Radiation therapy works by damaging the DNA inside the cancer cells, which causes the cells to die or stop growing. Radiation therapy can be delivered externally or internally, depending on the type and location of the cancer. In external beam radiation therapy, a machine called a linear accelerator is used to deliver the radiation from outside the body. In internal radiation therapy, also known as brachytherapy, radioactive sources are placed inside the body near the cancer.

Anticancer therapy refers to the various treatments used to treat cancer. The goal of anticancer therapy is to eliminate cancer cells while minimizing damage to healthy cells. Cancer treatment may involve a combination of different therapies, including surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy, hormonal therapy and stem cell transplant. Each of these treatments has its own benefits and drawbacks and the choice of treatment depends on the type and stage of cancer, as well as the overall health of the patient. Surgery is a common treatment for many types of cancer. The goal of surgery is to remove the cancerous tumor from the body. The surgery may be performed using a traditional open incision or minimally invasive techniques such as laparoscopic or robotic surgery. Surgery is often combined with other treatments such as radiation therapy or chemotherapy to ensure that all cancer cells are eliminated.
