Should I focus my common app essays on what I want to be?

<p>I'm a little apprehensive as to what I should write about on my short answer/personal statement...</p>

<p>My passion is cancer advocacy and I'm aspiring to be a doctor.</p>

<p>For the short answer, would it be better to write about being in a youth service club dedicated to fighting cancer or volunteering at the local food pantry?</p>

<p>Would it be too redundant to write about cancer in both short answer AND personal essay?</p>

<p>Thanks</p>
