Oncology

Oncology is a type of medicine that takes care of people who have cancer. Cancer is a sickness in the body where cells keep growing and multiplying when they should not. Oncologists are doctors who specialize in treating cancer and helping people who have it. They use different ways to fight the cancer, like surgery to take out tumors, chemotherapy to help stop cancer cells, and radiation to target cancer cells directly. Oncologists also help people with cancer by talking to them about their options and making sure they get the best treatments for their situation.
