Urine in healthy people has a mild smell. However, for some reason, urine becomes dark and has a foul smell, especially in women. It can be due to the smell of food, or it can be a sign of illness.

The smell of urine can be influenced by food and medical conditions. Some types of cancer can cause urine to have a bad smell, but the normal human nose cannot detect it. So what if you notice a bad odor from your urine and are concerned that this could be a sign of cancer? You can rest assured that cancer is not the cause of this change.
