Final answer:
The pharmacist would refer Ms. Supat to the side effects section of the package insert, which includes information on any increased cancer risk associated with her medication.
Step-by-step explanation:
If Ms. Supat is concerned about her cancer risk while taking her medication, the pharmacist should refer to the section of the package insert that discusses side effects and adverse reactions. Specifically, sections related to side effects often include information about increases in cancer risk associated with the medication.
The package insert contains various sections that detail the potential side effects, contraindications, and warnings for the users. For information on cancer risk, the pharmacist would likely point Ms. Supat to the section that outlines the negative side effects of the medication. Commonly this section may be labeled as 'Warnings' or 'Adverse Reactions', where there could be mentions of increased risk of various types of cancers such as breast cancer, ovarian cancer, endometrial cancer, colon cancer, etc., specific to the medication in question.
