Dear Dr. Smith,

Mr. Martin was seen in the office for continued management of his breast cancer. He's having some increasing pain in his breast which is due to the cancer. He is also complaining of neck pain. It does not seem to be worse at night; it seems to be worse with activity. He has no other symptoms. Otherwise, his review of systems is unremarkable. He's had no constitutional symptoms.

On physical exam, he is alert and oriented. Eyes: EOMI, PERLA, no icterus. The heart had a regular rate and rhythm; S1, S2 within normal limits. The lungs are clear to auscultation and percussion. The abdomen was soft, without masses or organomegaly. He was tender to palpation over the left anterior iliac crest. Otherwise, he had no point tenderness over his musculoskeletal system. Neck: Supple. No tenderness, no enlarged lymph nodes in the neck.

ASSESSMENT: Adenocarcinoma of the left breast, positive estrogen receptor status. Neck pain.

PLAN: The plan is to continue the Tamoxifen at this time. His laboratory studies were reviewed and were essentially unremarkable; however, we'll obtain a bone scan to ascertain the extent of his disease.

Sincerely, John Smith, M.D.
