UW–Madison researchers use AI to identify sex-specific risks associated with brain tumors
For years, cancer researchers have noticed that more men than women get a lethal form of brain cancer called glioblastoma. They’ve also found that these tumors are often more aggressive in men. But pinpointing the characteristics that might help doctors forecast which tumors are likely to grow more quickly has proven elusive.
