C. Tobacco
D. Increase of cancer with years living in the US"

Answer 1

The risk factor seen in 90% of all cancers is tobacco.

Step-by-step explanation:

A risk factor that is seen in 90% of all cancers is:

Environmental risk factors are the major risk factors for at least 90 per cent of human cancers. These include certain pathogens such as hepatitis viruses, nonpathogenic factors like radon and air pollution, and UV light from the sun. Other significant risk factors include smoking tobacco and poor diet/physical inactivity.

Answer: C. Tobacco

Answer 2

The risk factor that is seen in 90% of all cancers is C. Tobacco. Thus the correct option is C.

Step-by-step explanation:

Tobacco use is a significant and well-established risk factor for cancer. The statement that it is seen in 90% of all cancers reflects the strong association between tobacco consumption and the development of various types of cancers. The carcinogenic substances present in tobacco, such as nicotine and tar, are known to cause cellular damage and mutations, increasing the likelihood of cancer initiation and progression.

The link between tobacco and cancer has been extensively studied, and numerous research studies and epidemiological evidence support the assertion that tobacco use contributes significantly to the development of various cancers, including lung, throat, mouth, esophagus, and many others. The World Health Organization (WHO) and other health agencies recognize tobacco as a major preventable cause of cancer. Efforts to reduce tobacco use, such as anti-smoking campaigns, smoking cessation programs, and policy interventions, are aimed at mitigating this widespread risk factor and preventing a substantial proportion of cancer cases.

Understanding the prevalence and impact of risk factors like tobacco use is essential for public health initiatives and individual lifestyle choices. Promoting awareness and implementing measures to reduce tobacco consumption can play a crucial role in cancer prevention and overall public health improvement.
