What is cancer staging?
Cancer staging is a system used to describe the extent and spread of cancer within the body. It helps doctors determine the appropriate treatment options and predict the prognosis. Staging typically involves assessing the tumor size, involvement of nearby lymph nodes, and whether the cancer has metastasized (spread) to other organs or tissues.
How do doctors diagnose cancer?
Doctors use various methods to diagnose cancer. These may include physical examinations, imaging tests (such as X-rays, CT scans, or MRI scans), laboratory tests (such as blood tests or biopsies), and genetic testing. These diagnostic tools help doctors identify the presence, location, and stage of cancer.
What are the different types of oncologists?
There are three main types of oncologists: medical oncologists, surgical oncologists, and radiation oncologists. Medical oncologists use medications, such as chemotherapy, targeted therapy, and immunotherapy, to treat cancer. Surgical oncologists perform surgical procedures to remove tumors or affected tissues. Radiation oncologists utilize radiation therapy to target and destroy cancer cells.
