Write the information on modern diagnostics and treatment of cancer
Answers
Answer:Some people with cancer will have only one treatment. But most people have a combination of treatments, such as surgery with chemotherapy and/or radiation therapy. You may also have immunotherapy, targeted therapy, or hormone therapy.immunotherapy is a new form of cancer treatment that uses the immune system to attack cancer cells. Interventional radiology involves minimally invasive techniques using needles and catheters, and provides an alternative to surgery for some patients.
Explanation:
Answer:
Diagnostics of cancer: There are various techniques that are used in the diagnosis of cancer. The application completely depends upon the type of cancer. Radiography (use of X-rays), biopsy, CT Scan (Computed Tomography), histopathological studies of bone and blood, and MRI (Magnetic Resonance Imaging) is mostly used in the diagnosis of cancer. Some of the modern techniques such as Radiography, CT Scan, and MRI are used in cancer diagnosis.
1. MRI uses strong magnetic rays and non-ionizing radiations to accurately detect and identify pathological and physiological changes in the living tissue or body.
2. CT Scan uses X-rays to generate a three-dimensional image of the internal parts of a particular object or human body.
Treatment of cancer: Cancer can be treated by using three major approaches based upon the type of cancer. These approaches include surgery, radiotherapy, and chemotherapy.
1. In surgery, the tumor is removed from its site through operation and is applicable in specific body regions and cases only.
2. Radiotherapy is a technique in which the cancer cells are damaged with radiation and take care of the normal tissues surrounding the cancer cells.
3. Chemotherapy uses various types of drugs for treating cancer. These chemotherapeutic drugs can be used specifically for particular tumors only and they have a lot of side effects such as hair loss, paling of skin, anaemia, etc.
Most of the cancers can be treated by using a combination of all these three approaches.
