Which of the following is a type of cancer that can be caused by tobacco exposure?

• A. Melanoma
• B. Leukemia
• C. Squamous cell carcinoma
• D. Neuroblastoma

Answer: (C)

Squamous cell carcinoma is indeed a type of cancer associated with tobacco exposure. This form of skin cancer typically arises in the outer layer of skin (epidermis) and can be significantly influenced by environmental factors, including UV radiation and exposure to carcinogens found in tobacco smoke. The harmful chemicals in tobacco can damage the DNA in skin cells, leading to mutations that contribute to cancer development. On the other hand, while melanoma is primarily associated with UV radiation exposure from the sun or tanning devices, leukemia is a type of blood cancer that is primarily affected by genetic and environmental factors but is not directly linked to tobacco. Neuroblastoma is a cancer that mostly occurs in children and originates from neural tissue, and it is not known to be caused by tobacco exposure. Thus, squamous cell carcinoma stands out as the type of cancer influenced by tobacco, making it the correct choice.
