Generally no: While sputum cytology can assist in diagnosis under select circumstances, sputum color and/or consistency are not demonstrated to be indicators of malignancy.

Hard to answer: Yellow mucus can mean a lot of things: inflammation, smoking, etc. Sometimes, lung cancer can cause blood in the phlegm, but not always. Lung cancer can be hard to detect, as well. If you suspect you have lung cancer, would go see your doctor.
