I do not have debilitating, world-shattering migraines. I just get headaches. More days than not. I have one right now. My mom once had a headache for an entire year. (This remains a medical mystery.) I have on occasion had headaches that lasted so long that I expected to imitate her, although so far I don't think I've actually broken a full week (with breaks provided by ibuprofen).

I actually don't usually medicate them. I do that when they are so bad that they wake me up in the middle of the night, or when they occur early in the day; otherwise I let sleep take care of them.

The one time I tried aspirin for pain relief, I don't remember what it was for, although a headache was likely. I do remember that it gave me a stomachache which was worse than whatever it was supposed to get rid of for me. I wouldn't expect a tiny dose to have this effect, especially if I took it with food or something, but if I were forced to rely on it as my only analgesic, I would be in something of a quandary.

The question is not, "Which do you dislike more: headaches, or cancer?" It's, "Which do you prefer: effective pain relief for your extended, commonplace pain, or a risk-reducing drug which has not actually been extensively tested in your gender or age group?"
