As the song says, "Liar!". The market price for the uninsured with no special program, is a bit under $9,300,
https://www.drugs.com/price-guide/lynparza . Far from trivial, but well under the DUmmie-Liar-claimed $15,000. Below the clickbait-grade thread title, DUmmie-Liar
herding cats admits paying $500 a month (again, not trivial, but ~1/30 of the claimed price for
"My Lynparza". DUmmie-Liar
herding cats also admitted,
below the clickbait-grade thread title that there is a program through which Lynparza can be obtained "free"
(= paid for by those who pay open-market or very slightly reduced prices).
So DUmmie-Liar
herding cats lied in the thread title about what (s)he pays
(Lynparza may be used for pancreatic or prostate cancer), buried relevant facts that complicate his/her narrative, and gives no clue to understanding the costs of insurance-reduced and "free" prices.
Clue: When developing, testing, and clinical trials cost 10s or 100s of millions of dollars, the drug company will recoup its investment while its patent applies. Or they will go out of business.
