Correct Answer is A

Explanation

A) Correct. Regular screening tests like colonoscopy, endoscopy, and other imaging studies are crucial for early detection and diagnosis of gastrointestinal cancers.

B) Incorrect. There are effective screening methods available, and relying solely on symptoms may lead to delayed diagnosis.

C) Incorrect. While genetic testing and family history may be relevant for some individuals, they are not the primary methods for early detection of gastrointestinal cancers.

D) Incorrect. Biopsy is an important diagnostic tool, but it is not a primary screening method for gastrointestinal cancers.

Correct Answer is B

Explanation

A) Incorrect. While environmental factors can contribute to the development of cancer, they are not the primary cause. Genetic mutations play a significant role.

B) Correct. Gastrointestinal cancer, like other types of cancer, develops when normal cells in the gastrointestinal tract acquire genetic mutations. These mutations lead to uncontrolled cell growth and the formation of tumors.

C) Incorrect. While there can be a genetic component to some cases of gastrointestinal cancer, it is not exclusively inherited from one's parents.

D) Incorrect. While the exact cause of gastrointestinal cancer may not always be known, significant research has identified genetic mutations and other factors that contribute to its development.
