Cigarette smoking is a well-established cause of colorectal cancer and drinking large amounts of alcohol may also increase a woman's risk of developing the disease.
Smoking increases a person’s risk of developing colorectal cancer.
Smoking
Smoking increases a person's risk of colorectal cancer. One study of Finnish women and men showed a significant increase in the risk of colorectal cancer when comparing those who smoked one pack a day to those who never smoked. Smokers who stop can reduce their risk.
Alcohol Consumption
People who drink large amounts of alcohol may have increased rates of colorectal cancer, although this has been most clearly demonstrated in men. One study of American women showed an increased risk in women who had more than 11 drinks a week. Limiting the amount of alcohol you consume may reduce your risk of developing colorectal cancer.
