2. Eat healthy foods

Eating healthy foods isn't a sure way to prevent cancer. But it might lower the risk. Try to:

• Eat a lot of fruits and vegetables. Focus on fruits, vegetables and other foods from plant sources, such as whole grains and beans. Limit foods high in calories, fats and added sugars. Limit red meat, processed meats, refined grains, and saturated and trans fats.
• Drink alcohol only in moderation, if at all. Alcohol raises the risk of various types of cancer, including cancer of the breast, colon, lung, kidney and liver. The risk goes up the more you drink.

People who eat a Mediterranean diet have a lower risk of breast cancer. The Mediterranean diet focuses mostly on plant-based foods, such as fruits and vegetables, whole grains, legumes and nuts. People who follow the Mediterranean diet choose healthy fats, such as olive oil, rather than butter. And they eat fish instead of red meat.
