Older age and smoking are the biggest risk factors for developing any type of cancer over the next five years, according to a new study published in the journal Cancer. Researchers from the American Cancer Society collected data on almost 430,000 adults who were cancer-free and followed them for five years. Just over 15,000 of them developed cancer during that time. Current smoking turned out to be the biggest risk factor for developing cancer. Specifically for men, other cancer risk factors included alcohol intake, red meat consumption, physical inactivity, and family history of cancer. For women, body mass index, type 2 diabetes, hysterectomy, tubal ligation, and high blood pressure increased the risk of cancer.
