Final answer:
The claim that liver and throat cancer are associated with long-term alcohol abuse is true. Alcohol increases the risk for various cancers, including those of the liver and throat, by its carcinogenic byproducts. Cancer treatments may damage normal cells as they target rapidly dividing cells characteristic of cancer.
Step-by-step explanation:
The initial question regarding the association of liver and throat cancer with long-term alcohol abuse is true.
Long-term alcohol abuse is a well-known risk factor for several types of cancer, particularly those of the liver and throat. This association is due to the carcinogenic effects of alcohol and the byproducts of its metabolism. In the liver, excessive alcohol consumption can lead to cirrhosis, which can progress to liver cancer. Similarly, alcohol can also increase the risk of cancer in the pharynx, commonly known as the throat, as well as the mouth, larynx (voice box), esophagus, and other areas. It is recommended that individuals limit their alcohol intake to reduce their risk of developing these cancers.
With respect to the treatment of cancer, certain therapies like chemotherapy and radiation can damage normal tissue because they target rapidly dividing cells, which characterizes both cancerous and certain types of healthy cells. The collateral damage to normal tissues can result in a range of side effects and complications during cancer treatment.
