Cancerous cells are cells that have undergone genetic mutations that cause them to grow and divide uncontrollably. These cells can form a mass of tissue called a tumor. Tumors can be either benign or malignant.
Benign tumors: These tumors are non-cancerous and typically do not invade nearby tissues or spread to other parts of the body. They may grow slowly and often have well-defined borders.
Malignant tumors: These tumors are cancerous and can invade nearby tissues and spread to other parts of the body through a process called metastasis. Malignant tumors can be further categorized based on their tissue of origin (e.g., carcinoma, sarcoma, lymphoma, leukemia).
So, cancerous cells are the cells that make up malignant tumors, whereas benign tumors are made up of non-cancerous cells. The distinction between benign and malignant tumors is crucial for determining treatment strategies and assessing prognosis.

How do you tell when cells are cancerous?
Cancerous cells exhibit uncontrolled and inappropriate mitosis. Cancerous cells will often exhibit changed morphology and gene expression profiles, often assuming the shape and gene expression of more immature or more stem-like cells (a process termed de-differentiation). Cancerous cells often exhibit unusual karyotypes. Clinically, the precise identification of a cancerous cell can be difficult and will vary tissue to tissue. Another consideration is that for at least some cancers it is theorized that only a small proportion of cells within a tumor are actively cancerous. These cells are referred to as cancer stem cells. It is theorized that in some cases only a comparatively few cells are genuinely tumor-forming (i.e. uncontrollably dividing) and generating large growths of non-tumor forming cells of the visible tumor. Identifiying these actively tumor-forming cells remains a challenge in oncology.
What are cells that are not cancerous and have no affect on health called?
When a doctor does a biopsy on a suspicious lump, sometimes she discovers it is a "benign tumor" -- the cells are benign, that is, they are not cancerous and have no effect on health.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
Cancer or tumor .
What is A lump of cancerous tissue called?
A lump of cancerous tissue is typically referred to as a tumor. Tumors can be either benign or malignant. Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. Malignant tumors, on the other hand, are cancerous growths that have the potential to invade surrounding tissues and metastasize, or spread, to other parts of the body.
What two types of defects does a cancerous cell possess?
Cancerous cells possess defects that make proteins required for cell growth active and tumor suppressor genes inactive.
What is the relationship between cancerous and a tumor?
well one relationship that i know of is that the cancerous cell is what mainly causes the tumor to happen depending on what type of cancer you have
What is a uncontrolled division of cells?
A cancerous tumor.
What is the medical term meaning lump of cancerous cells?
A carcinoma is a cancerous tumor.
What is the technical term for a lump of cancerous cells?
It is called as malignant tumor.
What is a common term or cancerous cells that have spread in the body?
Malignant tumor
What is common term for cancerous cells that have spread in the body?
malignant tumor
Cancerous tumor cells are localized in a small area?
carcinoma in situ
What common term for cancerous cells that have spread in the body?
malignant tumor
What is a dense mass of abnormal cells called?
A mass of abnormal cells is a tumor. Sometimes this is cancer and sometimes not.
