Occasional alcohol consumption can still cause damage to the body. Alcohol is a toxic substance that can harm many organs, including the liver, heart, brain, and immune system [2]. Even a small amount of alcohol can have a negative impact on the body, especially in older adults [2].

Alcohol can also increase the risk of cancer, particularly breast, liver, and colorectal cancers [3]. The more alcohol a person drinks, the higher their risk of developing cancer [3].

Furthermore, alcohol can interact with medications and cause harmful side effects [1]. It is important to consult with a healthcare provider before consuming alcohol while taking medication.

In conclusion, occasional alcohol consumption can still cause damage to the body, including an increased risk of cancer and harmful interactions with medication. It is important to drink in moderation and to be aware of the potential risks associated with alcohol consumption [2][3].
