Final answer:
The synthetic hormones the patient started taking can affect the glandular and fatty tissue in her breasts, leading to changes in the mammography results.
Step-by-step explanation:
The synthetic hormones that the patient started taking 6 months prior to her current mammography can affect the glandular and fatty tissue in her breasts. The type of hormone therapy will determine the specific changes in the mammography results.
If the synthetic hormones contain estrogen, they can increase the glandular tissue in the breasts, leading to a mammography result showing increased glandular tissue compared with the previous result.
On the other hand, if the synthetic hormones contain progestin, they can decrease the glandular tissue and increase the fatty tissue, resulting in a mammography result showing decreased glandular tissue and increased fatty tissue compared with the previous result.
