Diagnosis of Cancer and Treatment

Q. Cancer cells are more easily damaged by radiation than normal cells because they are

1. Different in structure
2. Non-dividing
3. Starved of nutrients
4. Undergoing rapid division.

Q. Tumor cells have been shown to avoid detection and destruction by the immune system. Therefore, the patients are given certain substances called biological response modifiers (BRM) which activates their immune system and helps in destroying the tumor. Identify the BRM:

1. Alpha lactalbumin
2. Gamma globulin
3. Alpha interferon
4. Alpha-1 antitrypsin

Q. Cancerous cells can easily be destroyed by radiations due to :

1. Lack of nutirtion
2. Rapid cell division
3. Fast mutation
4. Lack of oxygen

Q. The diagnostic test that confirms typhoid in humans is [1 mark]
(A) ELISA
(B) Widal
(C) MRI

Q. Regarding assertion and reason, choose the correct option.
Assertion [A]: Interferon alpha helps in treatment of cancer indirectly.
Reason [R]: Interferons alpha is a biological response modifier.

1. Both A and R are true R does not explain A
2. Both A and R are false
3. Both A and R are true and R explains A
4. A is true and R is false

Q. What is auto immune disease? Give an example.

Q. Tumor cells have been shown to avoid detection and destruction by the immune system. Therefore, the patients are given certain substances called biological response modifiers (BRM) which activates their immune system and helps in destroying the tumor. Identify the BRM:
