Yes, cigars can cause cancer. The smoke from cigars contains numerous carcinogenic substances, including tar, benzene, cadmium, and formaldehyde. These substances can lead to multiple types of cancer, including cancers of the mouth, throat, esophagus, larynx, lung, and pancreas. Even if the smoke is not inhaled, the exposure to carcinogens through the lining of the mouth and throat is significant.
