The more government money is thrown at "health care", the higher the costs go -- much like government student loan "help" raises the cost of tuition. More money being thrown at the same amount of goods raises the price of the goods.

The price of chemotherapy drugs varies widely, depending on the drug. For example, according to research[3] from the American Society of Clinical Oncology, one course of a drug for chemotherapy for breast cancer can cost about $900-$15,000, depending on the drug(s); and, if growth factor support is added to lessen side effects, that increases costs from more than $4,000 to more than $30,000. According to an article[4] in the Journal of the National Cancer Institute, combination chemotherapy regimens typically used for advanced colorectal cancer can range from almost $12,000 to over $30,000 for an eight-week course, depending on the drugs. But new drugs usually cost more: for example, Adcetris[5] , a recently approved drug that treats recurrences of some types of lymphoma, can cost more than $120,000 for a course of treatment, and so does Yervoy[6] , a new skin cancer drug.

Note that many of the "not new" drugs are off-patent, some are actually from the 1950s, and likely cost pennies per dose to produce.
