Question

Which of these methods help in the confirmation of cancer detection?

• A. Biopsy, genome profiling, blood test
• B. ELISA, Biopsy, ultrasound
• C. Molecular biology, Biopsy, Radiography, ELISA
• D. A CAT scan with endoscopy

Answer 1

The correct option is C Molecular biology, Biopsy, Radiography, ELISA

Biopsy, Radiography, ELISA and Molecular biology are the methods that are followed for cancer detection. A biopsy involves taking out a sample of tissue from the area where abnormality is detected like for example, a lesion, tumour or simply a mass of cells and then analysed in a laboratory to locate cancer cells. Radiography includes tests like X-ray radiographs, roentgenogram contrast studies etc., which help doctors to look for cancer in different parts of the body like bones, stomach, liver, kidneys and other organs. ELISA stands for Enzyme-Linked Immunosorbent Assay, which helps to complement the cancer detection procedure by hunting for cancer-specific antibodies in the blood. Molecular biology can help in identifying tumour suppressor genes at the DNA and the mRNA level. Mutated or damaged tumour suppressor genes lead to cells multiplying uncontrollably.

The other options are partly true and by themselves, are not a stand-alone option.
