Now count words. Let's write content. Paragraph about PHESGO: "PHESGO is a prescription medicine that combines two monoclonal antibodies, trastuzumab and pertuzumab, designed for the treatment of HER2‑positive breast cancer." That's about 24 words. Add more: "It is indicated for patients with metastatic disease who have not previously received anti‑HER2 therapy, and it may be used in combination with chemotherapy to improve outcomes." That's about 30 words. Now total so far ~54 words. Now benefits list items: each bullet should be a short phrase, but count words. Bullet 1: "Targeted inhibition of HER2 signaling to slow tumor growth" (7 words) Bullet 2: "Enhanced immune system attack on cancer cells" (5 words) Bullet 3: "Used in combination with chemotherapy for improved efficacy" (7 words) Now list items count words: 7+5+7 = 19 words. Now active ingredient & action paragraph: maybe 50 words. "Trastuzumab and pertuzumab bind to distinct epitopes on the HER2 receptor, blocking its signaling pathways and promoting antibody‑dependent cellular cytotoxicity. Together they provide a dual‑blockade that reduces tumor proliferation and increases immune‑mediated tumor cell death." That's about 45 words. Now important notes paragraph: maybe 40 words. "Patients should be monitored for cardiac function, infusion reactions, and infections. The medication is administered intravenously under medical supervision, and dosage may be adjusted based on tolerance and response." That's about 38 words. Now total words: intro paragraph ~54 + benefits list items 19 = 73, plus active ingredient paragraph 45 = 118, plus important notes 38 = 156. Need 200-250 words total of visible text (including headings? Probably not counted). We need to add more content to reach 200-250 words. Let's expand intro paragraph and maybe add more sentences. Add more to intro: "PHESGO is supplied as a ready‑to‑use solution for intravenous infusion and is prescribed by oncologists familiar with HER2‑targeted therapies. The dosing schedule typically involves an initial loading dose followed by maintenance doses at regular intervals." That's about 35 words. Now total
