Which types of cancer are associated with exposure to ionizing radiation? 1. Leukaemia 2. Lung cancer 3. Breast cancer 4. Lymphoma Select the correct answer using the code given below.
Ionizing Radiation and Cancer Associations
Ionizing radiation is a known carcinogen, meaning it can cause cancer. Exposure increases the risk of developing certain types of malignancies.
Cancer Types Linked to Ionizing Radiation
Scientific evidence strongly associates exposure to ionizing radiation with several types of cancer. Based on established research:
- Leukaemia: A significant risk factor is identified between radiation exposure and the development of leukaemia.
- Breast cancer: Ionizing radiation, particularly at certain doses and ages, is a known risk factor for breast cancer.
- Lymphoma: Studies indicate a link between ionizing radiation exposure and an increased risk of lymphoma.
While lung cancer can be influenced by various factors, including environmental exposures like radon (which emits ionizing radiation), the primary associations highlighted in medical literature for direct ionizing radiation exposure often focus on leukaemia, breast cancer, and lymphoma.
Selecting the Correct Answer
The question asks to identify the cancer types associated with ionizing radiation exposure from the given list. Based on the established links:
- Leukaemia (1) is associated.
- Breast cancer (3) is associated.
- Lymphoma (4) is associated.
Therefore, the correct combination includes options 1, 3, and 4.
The correct option is 1, 3 and 4.
