Solution
Diagnostics of cancer:
There are many techniques whiich are used in the diagnosis of cancer and their application depends upon the type of cancer. Biopsy, histopathological studies of bone and blood, radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are used in diagnosis of cancer. Radiography, CT and MRI are the modern techniques used in cancer diagnosis.
Computed tomography uses X-rays to generate a three-dimensional image of the internals of an object. MRI uses strong magnetic fields and non-ionising radiations to accurately detect pathological and physiological changes in the living tissue.
Treatment of cancer:
Cancer is treated using 3 major approaches depending on the type of cancer. These 3 approaches are- surgery, radiotherapy and chemotherapy. In surgery, the tumor is removed surgically from its site and can be used in specific cases only. Radiotherapy is a technique in which the cancer cells are irradiated with radiations taking care of the normal tissues which surround the cancer cells.
Chemotherapy uses different kinds of drugs for the treatment of cancer. These chemotherapeutic drugs are specific for particular tumors and have side effects such as hair loss, anemia, etc.
Most of the cancers are treated by the combination of these 3 approaches.
