We May One Day Be Able To Detect Cancer With A Simple Blood Test

For the study, the team screened blood samples from patients with breast, lung, ovarian and colorectal cancers, looking for 58 genes typically linked with these cancers. Overall, they were able to detect 86 out of 138 stage I and stage II cancers. They also sequenced mutations in tumors from 100 of the patients studied, and found that in 82 patients, the same mutations found in the blood corresponded with those found in the tumor tissue.
