Select the correct statement :

(a) Cancer detection is based on biopsy and histopathological examination of the suspected tissue.

(b) Certain chemotherapeutic drugs may have side effects like hair loss and anemia.

(c) MRI employs strong magnetic fields and ionizing radiation to accurately detect changes in living tissues.

(d) Techniques such as radiography, CT scans, and MRI are useful for detecting cancers of internal organs.

a,b and d

The correct answer is Option (3) - a,b and d

a. The statement is true. Cancer detection commonly involves performing a biopsy, which is the removal of a small piece of suspected tissue. This tissue sample is then examined under a microscope through histopathological study to determine the presence of cancerous cells.

b. This statement is true. Chemotherapy drugs are often used to kill cancer cells. However, these drugs can have side effects such as hair loss (alopecia), anemia (reduced red blood cell count), and other adverse effects. The side effects vary depending on the specific drugs used and the individual's response to treatment.

c. This statement is false. MRI (Magnetic Resonance Imaging) utilizes strong magnetic fields and non-ionizing radiation, such as radio waves, to create detailed images of the body's internal structures. It does not involve the use of ionizing radiation.

d. This statement is true. Radiography (X-rays), CT (Computed Tomography) scans, and MRI are valuable diagnostic techniques for detecting cancers in internal organs. Radiography uses X-rays to produce images, CT scans provide cross-sectional images, and MRI utilizes magnetic fields to generate detailed images. These imaging techniques help identify abnormal growths or tumors in organs and aid in the diagnosis of cancer.

In summary, statements a, b, d, are true, while statement c is false.
