Question

Which of the following is curable in the next two decades?
A. Cancer
B. Poliomyelitis
C. Tuberculosis
D. None of the above

Answer 1

Hint: Cancer is one of the world's most feared diseases. The cell division mechanism in humans is quite good at controlling and regularising cell differentiation and proliferation. When a process called contact inhibition fails, uncontrolled cell division begins. Cell replication stops in healthy species when cells come into touch with other cells throughout this process.
As a result, contact inhibition becomes a potent anti-cancer mechanism, but in cancer cells it is lost. As a result, most cancers have tumours (except for cancers of the blood)

Complete answer:
Option A: The completion of the human genome is creating fundamental changes in thinking and direction in scientific research. Cancer may be curable in the next two decades. Cancer is produced by gene malfunction, which can be triggered by the activation of cancer-causing oncogene or the inactivation of tumour suppressor genes. The genes that cause cancer can be identified by comparing the activated genes in the tumour to those in normal cells. Parallel advances are being made in the fields of genetic engineering and biotechnology. All of these factors suggest that cancer may be cured within the next two decades.
So, option A is correct.
Option B: If the pulse polio programme succeeds, TB can be cured by using anti tubercular medications, and polio could be eradicated.
So, option B is not correct.
Option C: Vaccines against polio and tuberculosis are currently available in the form of polio vaccine and BCG, respectively.
In the next two decades, some tumours may be cured.
So, option C is incorrect.
Option D: The completion of the human genome is causing major shifts in scientific thought and research direction. In the next two decades, cancer may be curable. Gene malfunction causes cancer, which can be caused by the activation of cancer-causing oncogenes or the inactivation of tumour suppressor genes. All of these variables point to the possibility of curing cancer within the next two decades.
So, option D is not correct.

So, option A is the correct answer.

Note:
For cancer, there are three common therapy options.
Surgical removal of a localised malignant tumour (Effective for benign tumours)
Radiation therapy - Radiation is utilised to eliminate cancer cells in this therapy.
Chemotherapy is the process of using drugs to kill cancer cells.
