Oncology

From WikiMD's Food, Medicine & Wellnesspedia

Oncology is a specialized field within medicine focusing on the study, diagnosis, treatment, and prevention of tumors and cancers. At its core, oncology seeks to understand the aberrant cellular activities that result in cancer, a group of related diseases characterized by uncontrolled cellular division and the invasion of neighboring tissues.

Common Types of Cancer[edit | edit source]
