Q: Cancer survivors who do not have active cancer have a higher risk for severe COVID-19?
Although data is not very robust, it suggests that cancer survivors are prone to severe COVID-19 disease. The odd ratio can be up to 1.8. Unfortunately, patients with hematologic malignancy may have an even higher risk, up to fourfold. The risk decreases depending on the time difference between previous cancer and COVID infection.
