Researchers at Johns Hopkins University have discovered that cancer can be detected in the bloodstream a full three years before it’s spotted by doctors for an official diagnosis.
As detailed in a partially government-funded study published in the journal Cancer Discovery last month, the team found that genetic material being shed by cancer tumors can show up in the bloodstream far earlier than previously thought, paving the way for promising new cancer screening methods that could potentially head off the disease long before it gets more serious.
In some cases, the advanced detection could make the difference between being able to beat the cancer or not, according to the researchers.
