Breast cancer, if it metastasizes, typically goes where first?

A. The antibiotics didn't treat the infection

The antibiotics may have treated the original infection, but the new infection is a side effect of treatment.

B. She was allergic to the antibiotics

Allergy would present with rash, hives, or anaphylaxis, not a yeast infection.

C. She got a sexually transmitted infection from her partner

There's no indication of sexual transmission; the cause is linked to antibiotic use.

D. The antibiotics wiped out the normal flora of the vaginal area

Broad-spectrum antibiotics can disrupt the balance of normal flora, allowing opportunistic organisms like Candida (yeast) to overgrow, leading to a vaginal yeast infection.

A. Spleen

The spleen filters blood, but it's not the first common site of breast cancer metastasis.

B. Cervical lymph nodes

These are located in the neck and are not primary drainage sites for the breast.

C. Inguinal lymph nodes

These are in the groin and relate to drainage from the lower body, not the breast.

D. Axillary lymph nodes

These are located in the armpits and are the primary drainage nodes for breast tissue, making them the first site of metastasis.
