Question

The treatment of cancer with the use of gamma rays is called:
A. Hormone therapy
B. Chemotherapy
C. Radiation therapy
D. All of the above

Answer 1

Hint:- We know that radiation is somehow related to the optics/rays. So before going to the answer to this question, think about the types of rays that you have studied in the light spectrum.

Complete step-by-step solution:- Cancer nowadays has become the deadliest non contagious disease.
Cancer is recognized by the presence of tumors. Tumor is uncontrolled, abnormal and excessive growth of cells.
Tumor can be of two types:
a. Benign tumor: Benign tumor is encapsulated with unlimited growth within the capsule made up of connective tissue. It is non-invasive and non-metastatic.
b. Malignant tumor: Malignant tumor is non capsulated and delocalized. It possesses the property of metastasis which makes malignant tumor more lethal than benign tumor. Due to metastasis, malignant tumor travels along with blood streams and spreads its malignancy to the other target organs.
The tumor cells lack the property of contact inhibition due to which they undergo abnormal cell division creating a large mass of cells.
Treatment of cancer:
a. Radiation therapy: If X-rays, Gamma Rays and other ionizing rays are used for the treatment then it is known as Radiation therapy.
b. Immunotherapy: There are several methods that are involved in immunotherapy. The first one is the use of monoclonal antibodies. Example of this is alpha-interferons. The cells of the tumor suppress the immunological response of the body to mask their identity. Alpha interferons are biological response modifiers which help in boosting immunological response.
c. Chemotherapy: In chemotherapy there are certain chemicals that are being utilized for treatment. Example: Vincristine, Vinblastine and Taxol.
So the correct option is (c)Radiation therapy.

Note:-
Diagnosis is different from treatment.
Methods for the diagnosis of cancer:
a. Blood test: If the blood test for increasing the number of WBC’s i.e. more than 80000 per standard unit, then it shows that the person has leukemia or blood cancer.
B. Biopsy: It comes under histopathological test in which karyoplasmic index is tested.
Pap smear is used in the diagnosis of cervical cancer.
