Pheochromocytomas are most commonly:
A. Benign tumors
B. Malignant tumors
C. Found in both adrenal glands (bilateral) D. Located outside the adrenal glands (extra-adrenal)
The answer is A. Benign tumors.
While Pheochromocytomas can be malignant, around 10-15% of the cases, the majority, approximately 85%, are benign. This means they are not cancerous and are less likely to spread to other parts of the body.
Here's a breakdown of the other options:
B. Malignant tumors: As mentioned earlier, while some Pheochromocytomas are malignant, it's not the most common occurrence.
C. Found in both adrenal glands (bilateral): While it's possible to have Pheochromocytoma in both adrenal glands (around 10%), it's not the most common location.
D. Located outside the adrenal glands (extra-adrenal): While Pheochromocytomas can develop outside the adrenal glands, those occurring within the adrenal glands are more prevalent (around 85%).
