Question

The most common cause(s) of cancer deaths in the United States is/are: a. viruses b. radiation c. smoking d. poor diet and lack of exercise

Short answer

c. smoking

Step-by-step solution

Understanding Cancer Causes

Cancer can be caused by various factors such as viruses, radiation, smoking, and poor diet/lack of exercise. It's important to identify which of these is the most common cause of cancer deaths in the United States.

Evaluate Each Option

Evaluate each cause individually: Viruses can cause some cancers (like HPV leading to cervical cancer), radiation is a risk factor for cancer, smoking is a well-known and significant cause of cancer, and poor diet/lack of exercise are also risk factors.

Determine the Most Common Cause

According to health statistics and research, the leading cause of cancer deaths in the United States is overwhelmingly linked to smoking. It contributes substantially to lung cancer, which is the deadliest form of cancer.

Key concepts

cancer risk factors

Cancer is a complex disease with various risk factors. Knowing these factors can significantly aid in prevention.
Common cancer risk factors include:

• Genetics: Family history can increase your risk.
• Environmental exposures: Radiation and harmful chemicals can cause cancer.
• Lifestyle choices: Smoking, drinking alcohol, poor diet, and lack of exercise.
• Viruses and infections: Certain viruses like HPV can lead to cancers.

Understanding these risk factors can empower individuals to make better health choices and potentially reduce their cancer risk.

cancer statistics

Tracking cancer statistics helps us understand the impact of the disease.
Key points to consider:

• Cancer is the second leading cause of death globally.
• According to the American Cancer Society, lung cancer is the deadliest cancer in the United States.
• More than 1.8 million new cancer cases are diagnosed annually in the U.S.

By studying these statistics, researchers and policymakers can develop better prevention and treatment strategies.

smoking and cancer

Smoking is one of the most significant causes of cancer. It is linked to many types of cancer, but most notably lung cancer.
Key facts about smoking and cancer:

• Cigarette smoke contains toxic chemicals that can damage DNA and lead to cancer.
• Smoking is responsible for about 85% of lung cancer cases.
• It also increases the risk for cancers of the mouth, throat, esophagus, and bladder.

Quitting smoking can greatly reduce your cancer risk. Resources like nicotine replacement therapy and counseling can help people quit.

diet and exercise impact on health

A healthy diet and regular exercise can play a major role in cancer prevention.
Important considerations:

• Diets rich in fruits, vegetables, and whole grains are beneficial.
• Avoiding excessive red and processed meats can reduce cancer risk.
• Regular physical activity helps maintain a healthy weight, which lowers the risk of several cancers.

Incorporating healthy eating habits and staying active can not only reduce cancer risk but also improve overall well-being.
