Final answer:
The incorrect word in the sentence is 'everyday' which should be corrected to 'every day'. Aspirin, an anticoagulant, is used to prevent heart attacks and strokes in patients at risk for cardiovascular diseases, but it must be taken under medical advice due to possible side effects.
Step-by-step explanation:
The word that is used incorrectly in the sentence "Researchers at Queen Mary University of London have found that taking one low dose of aspirin everyday could lower the risk of certain cancers" is 'everyday'. The correct word should be 'every day', which means 'each day'; 'everyday' (when written as one word) is an adjective meaning 'common' or 'normal'.
Aspirin as a Preventive Measure
Aspirin (acetylsalicylic acid) is known for its role as an anticoagulant and is effective at inhibiting the aggregation of platelets. It is often prescribed to patients at risk for cardiovascular disease to take a low dose on a daily basis as a preventive measure against heart attacks and strokes. However, it is important to consult a physician before starting any aspirin regimen due to potential serious side effects such as an increased risk of ulcers.
