Correct answer
Explanation
Oncology is the branch of medicine that deals with tumors (neoplasms), both cancerous and non-cancerous. Serology studies blood serum and immune reactions, Chromatology studies colors, and Urology deals with the urinary system. The suffix '-ology' combined with 'onco-' (from Greek 'onkos' meaning mass or tumor) clearly identifies this field.
