Is it ok to take aspirin everyday?

Consult your doctor. Aspirin taken daily, in low doses, may reduce the risk of heart disease and cancer, but it has deleterious effects as well. You should consult your doctor before self medicating with Aspirin or any other drug/medication.
Depends. Aspirin offers benefits and dangerous side effects. For a thorough discussion of the topic see http://mdprevent.Blogspot.Com/2013/02/dr-oz-and-asprin-is-he-being.Html. Aspirin isn't for everyone and high cholesterol alone may not be an indication to take it. Other factors such as family history of heart attacks and strokes, high blood pressure, obesity, etc. Must weigh in so speak with your doctor.
