34/m - clear chest X-ray but still coughing up tiny amounts of blood 3-4x's a week. Slight loss in weight. Is this lung cancer related? Xsmoker

Coughing blood. This is unlikely to be cancer but nonetheless needs to be followed up with your physician and possibly a lung specialist.
Non cancer. Your cough is not due to cancer. You mayhave a postnasal drip which is responsible for your cough. Use salt water nose drops four times daily and congratulations on becoming an ex smoker.
