Which of the following does not play a role in determining whether individuals get cancer from a carcinogen?

1. their genetic makeup

2. how much of the carcinogen they are exposed to

3. their sex chromomes, or gender

4. how long they are exposed to a carcinogen

The correct answer is 3.

The sex hormones, or gender, would not be able to discriminate the occurrence of cancer, due to exposure to a carcinogen.

Gender may affect in the cases when the cancer is hereditary, and it sex-linked.

Otherwise, in non-hereditary cancers, the gender and sex hormones will not affect the chances of getting cancer.
