Most people who have a smoking-related cancer stop smoking or make serious efforts to quit when cancer is diagnosed. Patients who do not immediately stop smoking may be motivated to quit in the future. Some studies have shown that patients who have less intensive treatment are more likely to continue smoking, and if they quit, are more likely to start smoking again.

Glossary Terms

There are several main types of cancer. Carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.
