cancer - causes, signs and diagnosis human health and diseases zoology

  1. Interferon gamma

  2. Interferon alpha

  3. Inrerferon beta

  4. Reo-pro

Show answer
Correct Option: B
Explanation:
  • Interferon alpha is a biological therapy drug.
  •  It may be used to treat kidney cancer, melanoma, carcinoid tumours and some types of lymphoma and leukaemia. Interferon alpha is often called interferon.
  •  It is usually is used in the treatment of cancer given as an injection under the skin (subcutaneously). 
  • Hence, Interferon alpha is used in the treatment of cancer.
  • So, the correct answer is 'Interferon alpha'.

Which of the following is used for treatment of thyroid cancer?

cancer - causes, signs and diagnosis human health and diseases zoology

  1. U-238

  2. Ra-224

  3. C-14

  4. I-131

Show answer
Correct Option: D
Explanation:

Iodine-131 (I-131) is an important radioisotope of iodine. Iodine-131, in higher doses, is used for ablation (surgical removal) of remnant thyroid tissue following a complete thyroidectomy (removal of the thyroid gland) to treat thyroid cancer. I-131 is also used in nuclear energy, medical diagnostic and treatment procedures, and natural gas production.

So, the correct answer is 'I-131'.

Show answer
Correct Option: A

A recently discovered anti-cancer drug is obtained from ____________.

  1. Taxus

  2. Tagetes

  3. Tamaric

  4. Thea

Show answer
Correct Option: A

Treatment of cancer can be done by 

cancer - causes, signs and diagnosis human health and diseases zoology

  1. Radiation therapy

  2. Surgery

  3. Immunotherapy

  4. All the above

Show answer
Correct Option: D
Explanation:

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Treatment of cancer includes - 

  • Radiation therapy - It involves the use of ionizing radiation in an attempt to either cure or improve symptoms. It works by damaging the DNA of cancerous tissue.
  • Surgery - It is the primary method of treatment for most isolated, solid cancers and may play a role in prolongation of survival. In localized cancer, surgery typically attempts to remove the entire mass of tissue.
  • Immunotherapy - It plays a role in stimulating or helping the immune system to fight cancer.
So, the correct answer is 'All the above'.

Which of the following will be curable in next two decades?

cancer - causes, signs and diagnosis human health and diseases zoology

  1. Cancer

  2. Poliomyelitis

  3. Tuberculosis

  4. None of the above

Show answer
Correct Option: A
Explanation:

There are already vaccines available for Polio and tuberculosis.
In next two decades, cancer will be curable.
Thus, the correct answer is option (A), 'Cancer'.

Cancer treatment is a difficult process. Which of the following is a reason for it?

cancer - causes, signs and diagnosis human health and diseases zoology

  1. Cancer call can undergo uncontrolled division.

  2. Cancer cells adapt and evolve in response to treatment.

  3. Cancer cells become unresponsive to growth signals.

  4. All of these

Show answer
Correct Option: A
Explanation:
Cancer cells divide uncontrollably and exhibit properties such as loss of contact inhibition and loss of anchorage dependence which can also make them break away from the original site and travel to distant places in the body where they can begin forming a new cancer. This property is called as metastasis. Hence, treatment of cancer is a difficult process. Cancer cells become unresponsive to anti-growth signals which makes them grow uncontrollably.
So, the correct answer is, 'Cancer cell can undergo uncontroled division'.

Name of the drug used in cancer treatment produced using biotechnology.

cancer - causes, signs and diagnosis human health and diseases zoology

  1. Terramycin

  2. Streptomycin

  3. Humulin

  4. Interferon

Show answer
Correct Option: D
Explanation:

Interferon is the name given to a group of proteins known primarily for their role in inhibiting viral infections and in stimulating the entire immune system to fight disease. Interferons can inhibit cell division, which is one reason why they hold promise for stopping cancer growth. Interferons are members of a larger class of proteins called cytokines (proteins that carry signals between cells). Most interferons are classified as $\alpha$, $\beta$, or $\gamma$ interferons, depending on their molecular structure. Biotechnological advances making genetic engineering easier and faster are making protein drugs like interferons more available for study and use. Using recombinant DNA technology, or gene splicing, genes that code for interferons are identified, cloned and used for experimental studies and in making therapeutic quantities of protein. These modern DNA manipulation techniques have made possible the use of cell-signalling molecules like interferons as medicines.

Thus, the correct answer is option D.

A young person is suffering from cancer in tounge.His tounge is completely removed ,then which of the following situation will describe the person that he will be able to-

cancer - causes, signs and diagnosis human health and diseases zoology

  1. Taste sweet & salty.

  2. Not able to taste sweet,but able to taste salty.

  3. Perceive the odour of rose but not able to taste sweet and salt.

  4. Taste sweet and salty , but not perceive to the odour of rose.

Show answer
Correct Option: C
Explanation:

There are around 10,000 taste buds present in the tongue. The taste cells or gustatory cells are present in the taste buds. These are majorly present on the tip of your tongue. The taste buds for sweet are present on the tip of the tongue whereas the taste buds for salt are present on the sides of the tongue.

Hence, if the tongue is completely removed, these taste buds are also destroyed. This will result in loss of sweet and salty tastes along with other tastes.
Thus, the correct answer is option C.

The theory behind the use of lymphokines in cancer therapy is that

cancer - causes, signs and diagnosis human health and diseases zoology

  1. cancer cells bear antigens that should be recognizable by cytotoxic T-cells

  2. lymphokines stimulate the immune system

  3. if cancer develops, the immune system has become ineffective

  4. all of the above

Show answer
Correct Option: D
Explanation:

In the last fifteen years the role of cytokines in the modulation of anti-tumor responses has been extensively studied at the Institute of Microbiology of the University of Turin. In retrospect many observations appear to have been quite innovative and original. Altogether they form the steps of a consequential intellectual endeavour leading progressively towards a precise definition of the role of the lymphokines in modulating the immune response to neoplasia. Starting from the characterization of the tumor signals required for lymphokine induction, this research progressed towards the definition of the cellular, molecular and genetic mechanisms involved, and provisionally ends with the direct manipulation of lymphokine genes transfected to tumor cells.


So, the correct option is 'Option D'.
