Which organ cancers are associated with tobacco use that include the stomach or pancreas?

• A. Brain cancer
• B. Lymphoma
• C. Cancers of the stomach or pancreas
• D. Skin cancer

Answer: (C)

Tobacco exposure brings carcinogens into the body that can damage DNA in many tissues, so tobacco use is linked to several cancers, including those of the stomach and pancreas. The link to pancreatic cancer is well established: the risk rises with how much and how long someone smokes, and while quitting lowers the risk over time, it remains higher than in never-smokers for many years. For the stomach, smoking also increases cancer risk, particularly for certain subtypes, again with higher risk tied to longer and heavier smoking.

That’s why the option pointing to cancers of the stomach or pancreas is the best fit for this question. The other choices—brain cancer, lymphoma, and skin cancer—do not have as clear or strong a connection to tobacco in terms of organ-specific cancers, especially in the context of including the stomach or pancreas.
