Which cancers may increase with radiation exposure?

• A. Only lung cancer
• B. Testicular cancer and Non-Hodgkin's lymphoma
• C. Only blood cancer
• D. Only skin cancer

Answer: (B)

Radiation exposure is a well-documented risk factor for several types of cancer, and the selection of testicular cancer and Non-Hodgkin's lymphoma as the correct answer reflects this association.

Testicular cancer has been linked to radiation, particularly in individuals exposed during medical treatments or in occupational settings. The cells in the testes can be particularly sensitive to radiation, which may lead to mutations and the development of cancer.

Non-Hodgkin's lymphoma is also associated with radiation exposure. The lymphatic system is vulnerable to radiation's effects, which can lead to the proliferation of abnormal lymphocytes, the white blood cells involved in immune response, resulting in lymphoma.

Other types of cancer, such as lung cancer, blood cancer, and skin cancer, are associated with different carcinogenic factors and have their own unique risk profiles. While radiation can contribute to the risk of these cancers, the specified cancers in this context are particularly well-documented risks directly related to radiation exposure. Thus, the focus on testicular cancer and Non-Hodgkin's lymphoma captures the most relevant concerns in regard to radiation-related cancer risks.
