常見錯誤

❌The tumor on my wrist turned out to be a harmless cyst.
✅The lump on my wrist turned out to be a harmless cyst.
💡A cyst is a type of lump, not a type of tumor; using 'tumor' can wrongly imply cancer.
❌I have a cyst cancer.
✅I have a cyst, but it is not cancerous.
💡Cysts are usually not cancerous and should not be described as a type of cancer.
