Which of the following cancers is not associated with alcohol use?

Primary brain cancer is not typically associated with alcohol use. The link between alcohol consumption and various cancers is well-established, particularly for cancers such as breast, mouth, and stomach. Research indicates that alcohol can act as a carcinogen, with its effects varying by type of cancer. For instance, heavy drinking is known to increase the risk of oral and pharyngeal cancers, as well as being a risk factor for breast cancer, particularly in women. Stomach cancer has also been linked to alcohol consumption, especially with the presence of other risk factors like smoking and diet.

In contrast, primary brain cancer has not shown a consistent relationship with alcohol use. While some studies have explored the potential links between various substances and brain tumors, there is insufficient evidence to establish alcohol as a contributing factor in the development of primary brain cancers. This distinction highlights the specific nature of risk factors associated with different cancer types.
