Cancerous cells grow uncontrollably and can invade nearby tissues, while normal cells grow and divide in a regulated manner. Cancer cells can also spread to other parts of the body, a process called metastasis, which normal cells do not do. Additionally, cancer cells can evade the body's immune system and resist cell death signals, unlike normal cells.
Non-cancerous cells that do not affect health are referred to as normal cells. These cells function properly within the body and perform their intended roles without causing harm or disrupting the normal functioning of tissues and organs.

Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
metastasis
The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.
When cells reproduce out of control, it can lead to the formation of a mass of cells called a tumor. If the tumor is benign, it is not cancerous and typically does not spread to other parts of the body. However, if the tumor is malignant, it is cancerous and can invade nearby tissues or spread to other parts of the body, a process known as metastasis.
A non-cancerous abnormal cell is called a benign cell. Benign cells can form growths or tumors that do not invade surrounding tissues or spread to other parts of the body, unlike malignant (cancerous) cells. While benign tumors can still cause health issues depending on their size and location, they are generally considered less harmful than cancerous tumors.
