Sofia just had a biopsy of several lymph nodes to determine if her cells are dividing too quickly. If her test comes back positive, which type of doctor should she see next?

a cardiologist

an oncologist

a neurosurgeon

an orthopedist

The answer would be "an oncologist". Oncologists are medical practitioners qualified to diagnose and treat tumours.

Oncologist.

Oncologist may be defined as the doctor who has specialization in cancer and treats the disease by medication. Cancer may be defined as the uncontrolled growth of the cell division.

Sofia has the biopsy of lymph nodes and finds that her cells of lymph nodes are dividing quickly. This is the sign of cancer. To treat and confirm whether she is suffering from cancer, she should see the oncologist to treat her disease.
