What is the main treatment of a desmoid tumour, surgery or radiation?
Updated On: Jun 24, 2026
- Often seen below the umbilicus
- Unencapsulated
- More common in women
- Highly radiosensitive
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Picture the typical desmoid: a firm, locally invasive fibrous mass that favours the rectus sheath of the lower anterior abdominal wall, classically in a woman who has recently been pregnant. Some cases tie in with Gardner syndrome and FAP, and sporadic ones carry beta-catenin mutations.
Step 2: Test each option against this picture. Below the umbilicus, female predominance and an unencapsulated infiltrating edge are all true descriptions of the lesion.
Step 3: The remaining claim is that it is highly radiosensitive. In reality these fibromatoses respond poorly and the definitive treatment is wide excision, with radiation only an adjunct. So calling it highly radiosensitive is the incorrect statement.
\[\boxed{\text{Highly radiosensitive is not correct}}\]
