\nCancer refers to diseases in which abnormal cells divide out of control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems, which help the body get rid of toxins.1,2
\nThere are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start\u2014for example, lung cancer begins in the lung and laryngeal cancer begins in the larynx (voice box).1
\nSymptoms can include:3
\nSmoking can cause cancer and then block your body from fighting it:4
\nDoctors have known for years that smoking causes most lung cancers. It\u2019s still true today, when nearly 9 out of 10 lung cancers deaths are caused by smoking cigarettes or secondhand smoke exposure.5 In fact, people who smoke have a greater risk for lung cancer today than they did in 1964, even though they smoke fewer cigarettes. One reason may be changes in how cigarettes are made and what chemicals they contain.5
\nTreatments are getting better, but lung cancer still kills more men and women than any other type of cancer. In the United States, more than 7,300 nonsmokers die each year from lung cancer caused by secondhand smoke.6 Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by someone smoking.6
\nSmoking can cause cancer almost anywhere in your body, including the:5
\nMen with prostate cancer who smoke may be more likely to die from prostate cancer than nonsmokers.5
\nSmokeless tobacco, such as chewing tobacco, also causes cancer, including cancers of the:7
\nThe most important thing you can do to prevent smoking-related cancer is not to smoke cigarettes, or to quit if you do. It is also important to avoid secondhand smoke.
\nQuitting smoking lowers the risk for 12 types of cancer: cancers of the lung, larynx, oral cavity and pharynx, esophagus, pancreas, bladder, stomach, colon and rectum, liver, cervix, kidney, and acute myeloid leukemia (AML).8

\nReal stories about cancer:
\nResearch shows that screening for cervical and colorectal cancers, as recommended, helps prevent these diseases. Screening for cervical and colorectal cancers also helps find these diseases at an early stage when treatment is likely to work best. CDC offers free or low-cost cervical cancer screening nationwide.2 In addition, CDC\u2019s Screen for Life: National Colorectal Cancer Action Campaign informs men and women aged 50 years and older about the importance of having regular colorectal cancer screening tests.9
\nPeople who have smoked for many years may consider screening for lung cancer. The only recommended screening test for lung cancer is low-dose computed tomography (also called a low-dose CT scan, or LDCT). In this test, an X-ray machine scans the body using low doses of radiation to make detailed pictures of the lungs.
\nThe U.S. Preventive Services Task Force recommends yearly lung cancer screening with LDCT for people who:10
\nA pack-year is smoking an average of one pack of cigarettes per day for one year. For example, a person could have a 20 pack-year history by smoking one pack a day for 20 years or two packs a day for 10 years.10
\nThe task force recommends that yearly screening stop once a person has not smoked for 15 years, or develops a health problem that makes him or her unwilling or unable to have surgery if lung cancer is found.10
\nTalk to your doctor about lung cancer screening and the possible benefits and risks. Lung cancer screening is not a substitute for quitting smoking. If lung cancer screening is right for you, your doctor can refer you to a high-quality screening facility.11
\nThe treatment for cancer depends on the type of cancer and the stage of the disease (how severe the cancer is and whether it has spread). Doctors may also consider the patient\u2019s age and general health. Often, the goal of treatment is to cure the cancer. In other cases, the goal is to control the disease or to reduce symptoms for as long as possible. The treatment plan for a person may change over time.12
\nMost treatment plans include surgery, radiation therapy, or chemotherapy. Other plans involve biological therapy (a treatment that helps your immune system fight cancer).12
\nSome cancers respond best to a single type of treatment. Other cancers may respond best to a combination of treatments.12
\nFor patients who get very high doses of chemotherapy or radiation therapy, a stem cell transplant, also known as a bone marrow transplant, may be recommended by their doctor. This is because high-dose therapies destroy both cancer cells and normal blood cells. A stem cell transplant can help the body to make healthy blood cells to replace the ones lost due to the cancer treatment. It\u2019s a complicated procedure with many side effects and risks.12
\nQuitting smoking improves the outlook (the prognosis) for people with cancer. People who continue to smoke after diagnosis raise their risk for future cancers and death. They are more likely to die from cancer than nonsmokers and are more likely to develop a second (new) tobacco-related cancer.5
\nAn ostomy (or stoma) is a surgical opening made to the body that allows waste to be eliminated from the body.13 Ostomies are used in treatment or management of cancer or other diseases.14 Ostomies are needed when the body\u2019s normal opening is closed or altered as part of cancer treatment. An ostomy pouch is located around the opening to collect waste for removal. Ostomies are usually done during the first stages of surgical treatment to remove cancer.13 For patients with colorectal cancer, a colostomy (surgical openings from the bowel or colon to the abdomen) can be a lifesaving surgery.13,14 An ostomy can be temporary or permanent.13,14 Temporary ostomies are used while the affected area of the body heals. Permanent ostomies are used when cancer has resulted in the removal of the entire colon or the end of it.13,14
