Can you give the proper definition of cancer in simple words?

Answer 1

Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread).
malignant growth, malignant tumor; disease caused by these growths; invasive and evil influence

Answer 2

It is a disease where the cells in the body divide in a chaotic fashion. This uncontrolled division causes the cells to invade healthy tissues causing these tissues to stop performing their function correctly. This impairment can lead to death if not treated medically.

That's about as simple as I can put it :)

Answer 3

Cancer is a disease where abnormal cells in the body grow and divide uncontrollably, often forming tumors. These cells can invade nearby tissues and spread to other parts of the body, disrupting normal bodily functions.

Answer 4

Cancer is best described as a mutation. Cancer is more specifically a mutated genome in the DNA which causes abnormal cell manifestation and growth. It is a flaw in the human race.
