risk factor

A risk factor is a characteristic or condition that increases the likelihood of developing a health problem or disease. For example, smoking is a risk factor for lung cancer, meaning that smokers are more likely to develop lung cancer than non-smokers. Risk factors can be related to lifestyle, genetics, environment, or other health conditions. Recognizing risk factors can help individuals and healthcare providers make informed decisions to reduce or manage potential health issues. However, having a risk factor does not guarantee disease, it just increases the probability of its occurrence.
