Which is a safe technique to detect cancer ?A Radiography B CT (Computed tomography) Scanning C MRI (Magnetic Resonance Imaging) D Biopsy

To detect cancer, there are several techniques available. One safe technique is a biopsy. Here are the steps to perform a biopsy:

1. Consultation: The first step is to consult with a healthcare professional, such as an oncologist or a surgeon, who specializes in cancer diagnosis and treatment.

2. Medical history and examination: The healthcare professional will review your medical history and perform a physical examination to assess any signs or symptoms of cancer.

3. Imaging tests: Before a biopsy, imaging tests like radiography, CT scanning, or MRI may be conducted to locate the suspected cancerous area and determine its size and extent.

4. Biopsy procedure: A biopsy involves the removal of a small sample of tissue or cells from the suspected cancerous area. There are different types of biopsies, including:

   a. Needle biopsy: A thin needle is inserted into the suspected area to extract a sample of cells or tissue.

   b. Surgical biopsy: A surgical procedure is performed to remove a larger sample of tissue or the entire tumor.

5. Laboratory analysis: The collected tissue or cells are sent to a laboratory for analysis by a pathologist. They will examine the sample under a microscope and perform various tests to determine if cancer cells are present.

6. Diagnosis and treatment planning: Once the biopsy results are available, the healthcare professional will discuss the findings with you and provide a diagnosis. If cancer is detected, further tests may be required to determine the stage and extent of the disease. Based on the diagnosis, a treatment plan will be developed.

It is important to note that while radiography, CT scanning, and MRI can help in the initial detection and evaluation of cancer, a biopsy is the most definitive and accurate method to confirm the presence of cancer.
