Almost everybody knows that smoking can cause lung cancer. Are there other diseases caused by this habit? We asked cardiovascular specialist Christian Heesch, a physician who frequently deals with smoking related illnesses. “Smoking worsens and/or causes literally hundreds of illnesses, affecting the lungs, the heart, the vascular system, and pretty much every other part of the human body”, Christian Heesch told us. Many malignancies aside from lung cancer are more likely to occur in smokers. He added: “if you want to quit, and find it difficult to do on your own, talk to your doctor about ways to help you achieve your goal.”
