Question

Metastasis is connected with
A) Benign tumour
B) Malignant tumour
C) Both benign and malignant tumour
D) Crown gall tumour

Answer 1

Hint: Tumours are masses or malformations formed by clusters of aberrant cells. Tumour is also known as neoplasm. It is a mass of defective tissue that develops from post bodily cells for no apparent reason. Tumour may also refer to cancerous cells. Cancer cells differ from normal cells in proliferated cell division.

Complete answer:
Option B Malignant tumour: Malignant tumours have uncontrollable cell growth that spreads regionally and/or to different locations. Tumors that are malignant are cancerous. They migrate through the bloodstream or lymphatic system to different sites. Metastasis is the medical term for this type of spread.
So, option B is correct.
Option A Benign tumour: A benign tumour is a group of cells that lacks the potential to penetrate or spread to adjoining tissue. It is not connected with metastasis.
Option A is incorrect.
Option C Both benign and malignant tumours: Benign tumours do not have the capability to migrate to different sites. Only malignant tumours can move around to different parts of the body.
Option C is not correct.
Option D Crown gall tumour: Crown gall tumour is the tumour of plants. It affects different parts of the plant like roots, trunks etc. Metastasis is not associated with crown gall tumour.
Option D is not correct.

Hence, option B is the correct answer.

Note:
Cells with aberrant chromosomes and DNA have big, black nuclei and may be shaped abnormally. Our bodies are continually producing new cells to replace the ones that have died. In some cases, DNA is damaged throughout the process, resulting in aberrant cell development. Instead of dying, they keep multiplying faster than the immune system can handle, eventually becoming a tumour.
