Surgeon general report links more diseases, health problems to smoking tobacco
Fifty years after the U.S. surgeon general first linked cigarette smoking to deadly diseases such as lung cancer and heart disease, his successors continue to add to the list of health problems associated with tobacco use.
Smoking is a cause of liver cancer and colorectal cancer, the fourth-most-diagnosed form of the disease in the United States, Acting Surgeon General Boris D. Lushniak found in a report released Friday. In addition, he said, smoking is a cause of Type 2 diabetes mellitus, age-related macular degeneration, erectile dysfunction and rheumatoid arthritis. It can impair the immune system, worsen asthma and cause cleft lips and palates in fetuses. And exposure to secondhand smoke can cause strokes.
