How to become an Oncologist

There are many different paths that one can take to become an oncologist. The most common route is to first complete an undergraduate degree, followed by a four-year medical degree, and then complete a three-year residency in oncology. Some oncologists may also choose to complete a fellowship, which can add an additional one to two years of training.

The first step in becoming an oncologist is to obtain an undergraduate degree from an accredited college or university. Many oncologists choose to major in a science-related field, such as biology or chemistry, as this can help prepare them for the rigors of medical school. After completing a bachelor’s degree, students must then take the Medical College Admission Test (MCAT) before being accepted into medical school.

Once accepted into medical school, students will complete four years of training, during which they will learn about the various aspects of medicine. During the final year of medical school, students will rotate through different specialties, including oncology, to gain experience in each area. After graduation from medical school, students must then complete a three-year residency in oncology before they can be certified by the American Board of Oncology.

Some oncologists may also choose to complete a fellowship after their residency, which can add an additional one to two years of training. Fellowships are typically completed at cancer centers and allow oncologists to receive specialized training in a particular area of interest, such as breast cancer or pediatric oncology.
