Question

Which of the following is NOT a feature of cancer cells?
A) They divide in an uncontrolled manner.
B) They do not remain confined to one localized area.
C) They compete with normal cells for vital nutrients.
D) They show contact inhibition.

Answer 1

Hint: Cancer may be defined as a sickness during which tumour formation occurs. Also, the cancerous cells divide in an uninhibited manner and spread with time. They are different from normal cells and normal cells convert themself into cancerous cells after mutation.

Complete step by step answer: Cancer is concerned with abnormal cell growth with the potential to invade alternative components of the body. The tumour formation is of two types: malignant and benign. They will unfold to alternative components (not essentially like benign tumours). In malignant tumours, cells grow out of management and invade neighbor cells. They even unfold to the opposite part of the body. This is called metastasis. In such a style of a tumour, cells have lost the power to differentiate.
Let us look at the option in detail to get the correct answer,
-Option A is a feature of the cancer cells because cancer is the result of cells that grow unrestrainedly and don't die.
-Option B is also a feature of the cancer cells as it slowly escalates. With time, the onco-cells proliferate leading towards advanced stages.
-Option C is a feature of the cancer cells because these cancer cells contend with the normal body cells for varied very important nutrients.
-Option D is incorrect as the cancer cells don't show contact inhibition. Contact inhibition means the restriction of cell growth once they come in contact with one another. Contact inhibition could be a growth mechanism that functions to stay cells growing into a layer of one cell thick (monolayer). The cancer cells don't show this property as they divide and divide and compile and grow over one another and form tumours.
Hence, the correct answer is option D.

Note: There are various types of cancer depending upon the epicenter of the tumor. Today, various treatments are available to cure cancer. The treatments have shown higher effectiveness in the initial stages of the infection. Some of the treatments are chemotherapy, radiotherapy, hormone therapy, and immunological therapy. Several drugs are also being used to rehabilitate the patient.
