Dr. Jerome Coffey:

There are a couple of facts like that which are very blunt and hard to avoid. When one thinks about alcohol, one thinks about various things, but one does not think about head and neck cancer, oesophageal cancer and other gastrointestinal cancers. With smoking, one thinks about lung cancer, but one does not think about head and neck cancer, which is as morbid and as fatal. One does not think about bladder cancer. These common risk factors can cause a multiplicity of problems, both cancerous and otherwise.
