mammograms and sigmoidoscopy are methods for

c) early detection of breast and colon cancer, respectively.
d) removing cancerous cells from the breast and colon, respectively.

Explanation:

🆕 New Concept Discovered: Cancer Screening and Detection
Methods used to find cancer before symptoms appear.

Step 1: Define the purpose of mammograms

A mammogram is a specialized X-ray imaging technique used to visualize the internal structure of the breast. Its primary clinical purpose is the early detection of breast cancer, allowing for treatment before the disease progresses or spreads. It is a diagnostic and screening tool, not a treatment method for removing cells.

Step 2: Define the purpose of a sigmoidoscopy

A sigmoidoscopy is a minimally invasive medical procedure used to examine the inner lining of the large intestine, specifically the rectum and the sigmoid colon (the lower part of the colon). Its primary purpose is to screen for and enable the early detection of colorectal (colon) cancer and precancerous polyps. Like mammograms, it is primarily a screening and diagnostic tool rather than a primary treatment for removing cancer.

Step 3: Match with the given options

• Option a: Incorrect because sigmoidoscopy is used for colon cancer, not prostate cancer.
• Option b: Incorrect because both procedures are diagnostic screening methods, not surgical treatments for removing cancerous cells.
• Option c: Correct because mammograms screen for breast cancer and sigmoidoscopies screen for colon cancer.
• Option d: Incorrect because these procedures are used for detection, not for the removal of cancerous cells.

Answer:

c) early detection of breast and colon cancer, respectively.
