Bread with mold on it
Cancer is caused by a number of things. The more you limit risk factors the better. Certain foods people put into their bodies increase their risk of cancer. The fresher the food the better. I've seen people cut around or remove green moldy spots from foods such as bread and eat the rest. This is not a healthy practice.

Free radicals via the mold have permeated the food. Cutting around it does not remove all traces of the mold and make it good and healthy. If you maintain this negative practice, it will have a negative impact on your health. Do not eat foods that have traces of mold on them. Throw it away.
