A "family tree" has been compiled for prostate cancer

Peculiar genealogical trees compiled by scientists show that most of the oncogenic mutations are common to all secondary tumors in each patient. These shared genetic roots could potentially be the Achilles heel of metastases.

Why are medicines getting more expensive?

Over the past 10 years, the cost of clinical trials of one drug has increased by 2 times. If in the early 2000s it did not exceed an average of $1.2 billion, then in 2014 it reached $2.6 billion. According to experts, the cost of clinical trials can account for up to 50% of all investments in the development of a new drug.
