• 腫瘍しゅようCommon

• 腫しゅCommon
  noun (suffix)Seldom the word you want for 'tumor' on its own: 腫 is essentially a medical element meaning tumor, seen within compound terms rather than used independently — for that, 腫瘍 is the choice.

Use 腫瘍 when you need the word 'tumor' itself — an abnormal growth or neoplasm; 腫 is really a medical element meaning tumor that appears inside other terms, not a standalone word.
