Tobacco and Cancer
Tobacco use is a major risk factor for developing cancer. Smoking introduces harmful chemicals into the body, some of which have the ability to cause cancer. These toxic chemicals can damage the cells in various parts of the body, including the lungs, throat, and brain. With repeated exposure to tobacco, genetic changes may occur in these areas, increasing the risk of developing cancer.
The evidence from studies confirms that cigarette smoke not only increases the overall risk of cancer but also specifically raises the risk of cancer in multiple areas such as the lungs, bronchi, trachea, larynx, colon, pancreas, cervix, mouth, esophagus, bladder, kidney, liver, stomach, and acute myeloid leukemia.
Symptoms of cancer can vary depending on the type and stage of cancer. Common symptoms may include:
- Unexplained weight loss
- Fatigue or weakness
- Pain or discomfort in certain areas of the body
- Changes in skin appearance or texture
- Persistent cough or hoarseness
- Difficulty swallowing
- Persistent indigestion
- Changes in bowel or bladder habits
- Unusual bleeding or discharge
Reducing the risk of cancer from tobacco involves quitting tobacco use altogether. There is no safe level of tobacco use. Quitting smoking at any age can lead to substantial gains in life expectancy compared to those who continue to smoke. It is never too late to quit smoking. Even after years of heavy tobacco use, quitting can still significantly reduce the risk of developing cancer.
