How does nuclear medicine contribute to the treatment of cancer?

Nuclear medicine uses radioactive substances to diagnose and treat cancer.

Nuclear medicine is a branch of medicine that uses radioactive substances to diagnose and treat diseases, including cancer. In cancer treatment, nuclear medicine is used to deliver radiation directly to cancer cells, while minimizing damage to healthy cells. This is done through a process called radiation therapy, which involves the use of high-energy radiation to kill cancer cells and shrink tumors.

One type of nuclear medicine used in cancer treatment is called brachytherapy. This involves placing radioactive sources directly into or near the tumor, allowing for a more targeted delivery of radiation. Another type of nuclear medicine used in cancer treatment is called systemic radiation therapy, which involves injecting a radioactive substance into the bloodstream, allowing it to travel throughout the body and target cancer cells.

Nuclear medicine also plays a role in cancer diagnosis. One common nuclear medicine test used to diagnose cancer is called a PET scan. This involves injecting a small amount of radioactive substance into the body, which is then detected by a special camera that creates images of the body's cells and tissues. These images can help doctors identify cancerous cells and determine the best course of treatment.

In summary, nuclear medicine plays an important role in the diagnosis and treatment of cancer. By using radioactive substances to target cancer cells, nuclear medicine offers a more precise and effective way of treating cancer while minimizing damage to healthy cells.
