CANCER

The reason why many cancers develop is often unknown, but certain cancers do have
preventable causes. You may be thinking of skin cancer, which can be prevented by avoiding
too much sun; and lung cancer, which in the majority of cases is caused by smoking. But, did
you know that esophageal cancer (cancer of the esophagus) and larynx cancer, as well as other
head and neck cancers, are also caused by smoking? In addition, these cancers can develop from
excessive alcohol use, and when combined with smoking, the risk goes up even further.
Although it isn’t known exactly how alcohol leads to cancer, one theory suggests that it’s an
irritant that may cause cell changes (and make it easier for toxic substances from smoking to get
into cells). The best way to prevent these cancers is to never start smoking or, if you already
smoke, to quit. In addition, restrict your alcohol intake to the recommended limit of one drink
per day for women and two for men. Most people with alcohol use disorder can benefit from
treatment, which will help reduce their risk of these cancers.
