Divergent Boundaries. Divergent boundaries occur where plates are spreading apart. This spreading is caused by convective forces in the molten magma below them. As they slowly spread apart, this fluid basalt lava fills the gap and quickly solidifies, forming new oceanic crust.
Xtandi costs $7,450 per month. The average treatment course is eight months, so the cost of Xtandi is usually about $60,000 for a full course of treatment. Additional costs for doctor visits, co-pays, deductibles, parking fees, and travel expenses are not included in this amount.
Advantage: Good safety profile and proven clinical benefits. The price of Xtandi at $ 7,500 per month is prohibitively expensive for all but the richest men with prostate cancer. The annual cost is $ 89,000 so this is aimed at the Provenge end of the market which costs $ 93,000 per treatment.
